Promotion Not a Fundamental Right

Source: TOI

Why in News?

The Supreme Court in its recent judgement has reiterated that promotion is not a fundamental right for government servants in India, as the Constitution does not prescribe any criteria for filling promotional posts.

• This has been left to the discretion of the legislature and executive.

What are the Constitutional Provisions Related to Reservation?

• Article15 (6): It enables the State to make special provisions for the advancement of any economically weaker section of citizens, including reservations in educational institutions.
  • It states that such reservations can be made in any educational institution, including both aided and unaided private institutions, except minority educational institutions covered under Article 30 (1).
• Article 16 (4): Provides that the State can make any provision for the reservation of appointments or posts in favour of any backward class of citizens who, in the opinion of the state, are not adequately represented in the services under the State.
• Article 16 (4A): Provides that the State can make any provision for reservation in matters of promotion in favour of the Scheduled Castes and the Scheduled Tribes if they are not adequately represented in the services under the State.
• Article 16(4B): It enabled the unfilled SC/ST quota of a particular year to be carried forward to the next year.
  • Both Articles 16(4A) and 16(4B) were inserted by the 77^th Constitutional Amendment Act, 1995.
• Article 16 (6): It enables the State to make provisions for reservation in appointments. These provisions will be subject to a 10% ceiling, in addition to the existing reservations.
• Article 335: It recognises that special measures need to be adopted for considering the claims of SCs and STs to services and posts, in order to bring them at par.
• 82^nd Constitutional Amendment Act, 2000: It inserted a condition at the end of Article 335 that enabled the state to make any provision in favour of the members of the SC/STs for relaxation in qualifying marks in any examination.

What are the Pros and Cons of Reservation in Promotion?

Pros of Reservation	Cons of Reservation
Social Justice & Inclusion: Promotes representation of historically disadvantaged groups (SC, ST, OBC) in higher positions of services.	Merit vs Reservation: Raises concerns about overlooking the most qualified candidate for the promotion.
Breaks Caste & Social Barriers: Creates a more diverse and inclusive leadership structure, fostering better understanding of societal issues.	Demotivation & Frustration: Can lead to demotivation and frustration among general category candidates who feel passed over.
Empowerment & Upliftment: Offers marginalised communities opportunities to advance and compete at higher levels.	Creamy Layer Issue: The "creamy layer" within reserved categories might still benefit, negating the upliftment purpose.
Positive Discrimination: Addresses past discrimination by offering a helping hand to overcome ingrained social and economic barriers.	Seniority & Efficiency: Reservation in promotions can disrupt seniority-based promotion systems, impacting overall efficiency.

What are the Reservation Related Developments in India?

• Indra Sawhney Judgment, 1992:
  • In this nine-judge bench judgement held that Article 16(4) of the Constitution, which allows reservation in appointments, does not extend to promotions.
  • Court upheld the constitutionality of the 27% reservation but put a ceiling of 50% unless exceptional circumstances warranting the breach, so that the constitutionally guaranteed right to equality under Article 14 would remain secured.
  • Carry forward rule is valid but it is subject to 50%. There should be no reservation in the promotions.
  • The court clarified that Article 16(4) is not a separate rule that overrides Article 16(1). The article 16(1) is a fundamental right, article 16(4) is an enabling provision.
    • Article 16(1): It states that there shall be equality of opportunity for all citizens in matters relating to employment or appointment to any office under the State.
  • Further, the Court directed to exclude Creamy Layer (economically well-off) from Other Backward Classes (OBCs) from getting reservation benefits.
    • However, it specifically excluded SCs and STs from this concept.

• M. Nagaraj Judgment, 2006:
  • This judgement partially overturned Indra Sawhney judgement.
  • It introduced a conditional extension of the "creamy layer" concept to SC/ST communities seeking promotions in government jobs.
    • This concept was previously applied only to Other Backward Classes (OBCs).
  • Judgement laid down 3 conditions to allow states to provide reservations in promotions for SCs/STs, as:
    • Inadequacy of Representation: The state must demonstrate SCs/STs are inadequately represented in promotions.
    • Creamy Layer Exclusion: Reservation benefits should not extend to the "creamy layer" within SCs/STs.
    • Maintain Efficiency: Reservation should not affect overall administrative efficiency.
• Jarnail Singh vs Union of India, 2018:
  • In this case, the Supreme Court (SC) reversed its stance on data collection.
  • States No Longer Need Quantifiable Data: The SC ruled that states no longer needed to collect quantifiable data to prove the backwardness of the SC/ST community when implementing reservation quotas for promotions.
  • It allowed the government to implement "accelerated promotion with consequential seniority" for SC/ST members more easily.

• Janhit Abhiyan v. Union of India, 2022
  • It challenged the 103rd Constitutional Amendment that introduced a 10% reservation for Economically Weaker Sections (EWS) in educational institutions and government jobs.
    • In a 3-2 verdict, the Court upheld the amendment.
  • It allowed the government to provide reservation benefits based on economic standing, alongside existing reservations for disadvantaged social groups.

Way Forward

• Data-Driven Approach: It is needed to assess the current representation of SC/ST/OBCs across different levels and departments. This data can be used to establish concrete targets for filling reservation quotas.
• Focus on Merit with Relaxation: Promoting a system that emphasises merit while allowing for some relaxation in qualifying marks for SC/ST/OBC candidates in promotions, ensuring that qualified candidates from these communities have a better chance while maintaining an acceptable competency level.
• Addressing Concerns: Acknowledge concerns about unqualified candidates getting promoted due to reservations.
  • Propose solutions like rigorous training and mentorship programs for promoted SC/ST/OBC employees to bridge any skill gaps and ensure they excel in their new roles.
• Long-Term Vision: Emphasise that reservations are a temporary measure to achieve long-term social justice and equal opportunity in promotions.
  • Advocate for parallel initiatives that improve education and access to resources for these communities, ultimately leading to a situation where reservations may not be necessary.

Conclusion

The Supreme Court's approach on reservation in promotions has evolved over time, balancing the competing principles of equality and affirmative action. While the Court has allowed states to provide such reservation, it has also imposed certain conditions to ensure that it does not compromise administrative efficiency and the overall public interest.

Drishti Mains Question: Reservation in promotions for SCs, STs, and OBCs presents a challenge in balancing inclusivity with bureaucratic efficiency. Critically examine strategies to ensure both objectives are met effectively in the Indian administrative system.

Increased Recovery Under IBC

Source: ET

Why in News?

Recent data from the Insolvency and Bankruptcy Board of India (IBBI) shows, creditors in India have retrieved almost half of their claims under the Insolvency and Bankruptcy Code (IBC), 2016 when resolutions are concluded within the 330-day deadline, although delays have diminished the proportion of money recovered.

What are the Key Highlights of the Latest Data?

• Recovery Rates and Timeliness:
  • Data shows that 947 financially stressed companies' resolutions resulted in creditors receiving ₹3.36 lakh crore, equivalent to 32.1% of their claims since the inception of the IBC (2016).
  • Stress resolution under the Insolvency and Bankruptcy Code (IBC), 2016 has improved in recent years, but recoveries have not kept pace.
    • Recoveries by creditors were at 54% in FY18 and FY19 but dropped to 22% in FY21 due to the pandemic.
    • Recoveries inched up to 23% in FY22 and 36% in FY23 before declining again to 27% in FY24.
  • The number of resolutions reached a record 269 in the last fiscal year (FY 24), up from 189 in FY23 and 144 in FY22, mainly due to government filling National Company Law Tribunal (NCLT) vacancies in the past two years.
  • Creditors have experienced stronger cumulative recoveries compared to the fair value of stressed companies upon insolvency admission, at 85%.
    • In terms of liquidation value, the recovery rate has reached 161.8% of the assets.
  • Experts stress the importance of timely initiation of the Insolvency and Bankruptcy Code (IBC) for stress resolution, as delays (averaging 679 days) have lowered recovery rates to 26%, impacting asset value and debt recovery.

What are the Proposed Measures to Strengthen IBC?

• Reduce Delays: Efficiently resolving insolvency cases within the IBC's 330-day deadline is imperative, with the current average duration of 679 days underscoring the need for streamlining processes and reducing litigation.
• Improve Recovery Rates: While the IBC has led to resolutions, the percentage of claims recovered by creditors needs improvement. It dropped from 49% for on-time resolutions to 26% for delayed ones. It can be achieved by:
  • Ensure sufficient judges and staff at the NCLT to handle cases efficiently to expedite processing and reduce delays caused by backlogs.
  • Review and simplify the IBC procedures to eliminate unnecessary steps and expedite approvals involving standardising processes.
• Sector-Specific Regimes: Consider specialised insolvency regimes for sectors like real estate, which may have unique challenges compared to other industries.
• Cross-Border Insolvency Framework: Establish an effective legal framework based on the UNCITRAL (United Nations Commission on International Trade Law) to handle insolvency cases involving companies with assets in multiple countries.
• Review Timelines: Re-evaluate the timelines mandated by the IBC to ensure they are efficient and minimise unnecessary delays.
• Formal Prepack for All Companies: Allow a formal pre-packaged insolvency process for all companies, not just Micro, Small and Medium Enterprises (MSME). This involves agreeing on a resolution plan before initiating formal bankruptcy proceedings.

What are the Key Highlights of the Insolvency and Bankruptcy Code, 2016?

• About:
  • The Insolvency and Bankruptcy Code (IBC), 2016 provides a framework for resolving the bankruptcy and insolvency of companies, individuals, and partnerships in a time-bound manner.
    • Insolvency is a state where the liabilities of an individual or an organisation exceed its assets and that entity is unable to raise enough cash to meet its obligations or debts as they become due for payment.
    • Bankruptcy is when a person or company is legally declared incapable of paying their due and payable bills.
  • The Insolvency and Bankruptcy Code (Amendment) Act, 2021 modified the 2016 Code to offer a more efficient insolvency resolution framework for MSMEs, ensuring quicker, cost-effective, and value-maximising outcomes for all stakeholders.
• Insolvency and Bankruptcy Board of India (IBBI):
  • IBBI serves as the regulatory authority overseeing insolvency proceedings in India.
  • The IBBI's Chairperson and three full-time members are appointed by the government and are experts in the fields of finance, law, and insolvency.
  • It also has ex-officio members.
• Adjudication of Proceedings:
  • National Companies Law Tribunal (NCLT) adjudicates proceedings for companies.
  • Debt Recovery Tribunal (DRT) handles proceedings for individuals.
    • They play a pivotal role in approving the initiation of the resolution process, appointing professionals, and endorsing the final decisions of creditors.
• Procedure for Insolvency Resolution under the Code: Initiated by either debtor or creditor upon default, insolvency professionals manage financial information and debtor assets, with a 180-day legal action prohibition during resolution.
• Committee of Creditors (CoC): The CoC, formed by insolvency professionals and comprising financial creditors, determines the fate of outstanding debts through debt revival, repayment schedule changes, or asset liquidation, with a 180-day deadline before the debtor's assets are liquidated.
• Liquidation Process: Proceeds from the sale of the debtor’s assets are distributed first to insolvency resolution costs, second to secured creditors, third to dues for workers and employees, and fourth to unsecured creditors.

Pandemic Treaty

Source: WHO

Why in News?

Recently, the World Health Assembly (WHA) in the annual meeting, agreed on a set of critical amendments to the International Health Regulations (2005) (IHR), and made concrete commitments to completing negotiations on a global pandemic agreement by 2025.

• These amendments will strengthen global preparedness, surveillance and responses to public health emergencies, including pandemics.

What are the Key Amendments Agreed to IHR?

• Definition:
  • Introduction of a definition of pandemic emergency to enhance international collaboration in response to potential pandemics.
  • Definition includes criteria such as wide geographical spread, exceeding health system capacity, causing social and economic disruption, and requiring rapid international action.
• Commitment to Solidarity and Equity:
  • It includes establishing a Coordinating Financial Mechanism to support the identification and access to financing needed to address the needs and priorities of developing countries.

  • The overuse and misuse of antibiotics in one country can create resistant bacteria that spread globally. Global cooperation helps in
    • Standardised Practices: Establishing common guidelines for antibiotic use in humans and animals helps slow resistance.
      • According to the WHO, antimicrobial resistance is a global health threat that could lead to millions of deaths each year if not addressed collaboratively.
• Chronic Disease Management:
  • Non-communicable diseases like heart disease and diabetes are a growing global concern. Cooperation helps in knowledge sharing.
    • Sharing best practices in prevention, treatment, and lifestyle interventions allows countries to learn from each other. For example, the Global Alliance for Chronic Diseases (GACD).
• Health Equity and Access:
  • Many countries lack the resources to tackle health challenges effectively. Global cooperation promotes technology transfer.
    • Sharing knowledge and technology allows developing countries to improve their healthcare systems. Initiatives like the Medicines Patent Pool facilitate access to affordable generic drugs.

What is the Existing Framework for Global Health Cooperation?

• Multilateral Agencies:
  • Various multilateral organisations like WHO, UNICEF, UNFPA, and UNAIDS play crucial roles in specific health areas like child health, reproductive health, and HIV/AIDS.
  • The WHO acts as the central coordinating authority on global health within the United Nations system.
    • It sets international health standards, provides technical assistance to countries, and monitors and coordinates the global response to health emergencies.
• International Health Regulations (IHR):
  • This is a legally binding agreement between 196 countries. It outlines the rights and obligations of countries regarding public health events with international implications.
• Global Health Initiatives:
  • These are targeted programs tackling specific health challenges. Examples include the Global Fund to Fight AIDS, Tuberculosis and Malaria, and Gavi, the Vaccine Alliance.
• Public-Private Partnerships:
  • Collaboration between governments, NGOs, and the private sector allows for leveraging resources and expertise.
    • Example, Bill & Melinda Gates Foundation.
• Regional Organizations:
  • Regional bodies like the Pan American Health Organization (PAHO) for the Americas and the African Union play a role in coordinating health efforts within their regions.

Conclusion

The World Health Assembly's (WHA) recent amendments to the International Health Regulations (IHR) and commitment to a global pandemic agreement by 2025 signify a significant step towards improved global health security.

Rising Global Temperatures

Source: IE

Why in News?

The world is witnessing a concerning trend of record-breaking temperatures across the globe, exacerbated by global warming. From the scorching 56.7°C recorded in Death Valley, California over a century ago to the recent 52.9°C reading in Delhi, temperature extremes are becoming more prevalent as the planet continues to heat up.

• If the 52.9°C recorded at a station in Delhi is verified, it would be an all-time high for India.

What is the Historical Context of Global Temperature Records?

• Historical High: The highest temperature ever recorded on Earth was 56.7°C in Death Valley, California, in 1913.
  • United Kingdom: Surpassed 40°C for the first time in July 2022.
  • China: Recorded its highest temperature of 52°C in a northwestern town last year.
  • Europe: Sicily, Italy, reached 48.8°C in 2021, a record for the continent.
  • India: Rajasthan's Phalodi recorded the highest temperature of 51°C in 2016.
• Global Trends: An analysis shows nearly 40% of the Earth experienced its highest-ever daily temperature between 2013 and 2023.
  • This includes diverse regions, from Antarctica to various parts of Asia, Europe, and the Americas.
  • Global average temperatures are currently about 1.61°C higher than pre-industrial levels.

How Global Warming is Exacerbating Global Temperatures?

• Definition: Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases (GHG) like carbon dioxide (CO₂) and methane (CH₄).
• Greenhouse Gases and Temperatures: GHGs trap heat in the Earth's atmosphere, preventing it from escaping into space.
  • Increased concentrations of these gasses enhance this effect, leading to more heat being retained and higher global temperatures.
• Global Temperature Rise: The planet's average surface temperature has risen about 1°C since the late 19^th century, a change driven largely by increased GHG emissions into the atmosphere and other human activities.
  • The past decade has seen many of the warmest years on record, with 2023 and 2024 showing unprecedented temperature increases.
  • The period from May 2023 to April 2024 was the warmest 12-month period, with global temperatures about 1.61°C above pre-industrial levels.
• India Compare to Global Warming Trends: India's warming is less than the global average.
  • Indian temperatures have increased by 0.7 degrees Celsius since 1900, while global land temperatures have risen by 1.59°C. When including oceans, global temperatures are now at least 1.1°C higher than pre-industrial levels.
• Global Warming and Heatwaves: Global warming is causing an increase in global temperatures and the frequency of heatwaves.
  • In India Heat waves typically occur from March to June, and in some rare cases, even extend till July. On an average, five-six heat wave events occur every year over the northern parts of the country.
  • Heatwaves in India are becoming more severe, with heatwave conditions even in February, a winter month for which heatwave thresholds are not defined.
    • The current high temperatures in Delhi and North India seem abnormal compared to the average temperatures from 1981-2010.
    • In the future, temperatures of 45°C and above may become the new normal, and a reading of 50°C will no longer be seen as unusual.
• Geographical Variability: Global warming is not causing a uniform rise in temperatures everywhere. Some regions experience faster warming due to factors like:
  • Polar Amplification: The Arctic and other polar areas are warming much faster due to melting sea ice and permafrost.
  • Land vs Water: Land warms faster than oceans, so continental interiors warm faster than coastal regions.
  • Elevation: Higher elevations experience slower warming as the atmosphere traps less heat.
  • Ocean Currents: Regions influenced by warm currents like the Gulf Stream warm faster.
  • Landlocked Countries: Landlocked areas have less evaporative cooling and the continental effect, leading to more extreme temperature swings.
• Urban Heat Islands (UHIs): UHIs are metropolitan areas significantly warmer than surrounding regions due to heat-absorbing surfaces and energy use.
  • As global temperatures rise, UHI intensity is expected to increase, amplifying heatwaves in cities.
  • The higher urban temperatures also drive greater fossil fuel-powered cooling, further contributing to GHG emissions and warming.
  • Populations in UHIs are especially vulnerable to the health risks posed by the compounded effects of UHIs and climate change.

What are the Consequences of Rising Global Temperatures?

• Sea Level Rise: As temperatures rise, glaciers and ice sheets melt, adding water to the oceans and causing sea levels to rise. This inundates coastal areas, displaces communities, and disrupts ecosystems.
  • Global sea level has risen by about 8 inches since 1880 and is projected to rise by at least another foot by 2100. In a high-emissions scenario, it could potentially rise as high as 6.6 feet.
• Ocean Acidification: The oceans absorb a significant amount of the CO2 released into the atmosphere. This makes the oceans more acidic, harming marine life and disrupting ocean ecosystems crucial for the health of the planet.
  • Hurricanes are expected to become stronger and more intense as the climate warms, leading to increased storm intensity and rainfall rates.
• Droughts and Heat Waves: Droughts and heat waves are expected to become more intense, while cold waves are expected to become less intense and less frequent.
• Wildfire Season: Wildfire season has been prolonged and intensified due to warming temperatures and long-term drought, increasing the risk of fires.
  • Human-caused climate change has already doubled the area of forest burned and is projected to further increase the amount of land consumed by wildfires in Western states by around 2050.
• Biodiversity Loss: Rising temperatures and changing weather patterns disrupt ecosystems and habitats, pushing many plant and animal species towards extinction.
• Climate change: Extreme weather disrupts food production, leading to shortages and price hikes that harm vulnerable populations.
  • Rising temperatures worsen air quality, increase heat-related illnesses, and facilitate disease spread.
  • The economic consequences are severe, with high costs for repairing infrastructure, declining agricultural yields, and escalating disaster relief.

Way Forward

• Six-Sector Solution: Follow the United Nations Environment Programme’s roadmap, which includes reducing emissions across sectors like energy, industry, agriculture, forests, transport, and buildings.
• Carbon Offsetting: Invest in projects that draw down carbon from the atmosphere, such as reforestation or carbon capture and storage.
• Reduction in Greenhouse Gas Emissions: Transition to renewable energy sources like Solar, wind, geothermal, and hydro power can significantly reduce our dependence on fossil fuels.
  • Implementing energy-efficient practices in homes, industries, and transportation can drastically cut down on energy consumption.
• Sustainable Agriculture: Adopt climate-smart agricultural practices, such as sustainable irrigation techniques, drought-resistant crop varieties, and agroforestry.
  • Enhance food storage and distribution systems to minimise losses and ensure access to food during extreme weather events.
  • Reducing deforestation, utilising regenerative agriculture techniques, and promoting plant-based diets can all contribute.
• Support Climate-Vulnerable Populations: Assist communities most vulnerable to climate change impacts, such as those in low-lying coastal areas and developing countries.

Drishti Mains Question: Q. Evaluate the role of global warming in exacerbating heatwaves and its impact on urban heat islands. How can urban planning mitigate these effects?

Migratory Diadromous Fishes

Source: DTE

Why in News?

A recent study has raised concerns about the effectiveness of Marine Protected Areas (MPAs) in safeguarding the habitats of rare migratory fish species.

• The study found that a significant portion of these protected areas do not align with the core habitats of the target species, raising questions about the efficacy of current conservation efforts.

What are the Findings of the Study about Diadromous Fish Species?

• About Study:
  • The study examined 11 rare and data-poor diadromous fish species. These species migrate between saltwater and freshwater environments.
• Findings:
  • The researchers found that only 55% of the modelled core habitats for these species overlapped with the designated MPAs.
    • And, of these protected areas, only 50% had measures in place for the protection of the fish.
  • Less than 30% of endangered species, such as the Mediterranean twaite shad, had their core habitats within the MPAs.
  • Species like European eel and European smelt, which had nearly 70% of their core habitats within MPAs.
• Challenges faced by these fishes:
  • Diadromous fish are highly sensitive to a range of anthropogenic pressures such as agricultural and pollutant runoffs, habitat destruction, barriers to migration, fishing, bycatch, and climate change.
  • Barriers to migration, such as dams, weirs, and locks, can have a significant impact on these fish as they move between freshwater and marine habitats throughout their life cycle.
• Impact of Climate Change:
  • Fish are Swimming Further North in the Ocean because warmer waters are pushing them towards cooler areas.
  • Southern Populations of these Fish are Declining Significantly due to factors like habitat loss or changes in food availability.
  • The Timing of their Migrations is also Changing, which can harm the survival of their young and make it harder for them to find food.

What are Diadromous fishes?

• About:
  • These are a group of fish that migrate between freshwater and saltwater environments throughout their lives.
  • This unique life cycle allows them to take advantage of the different resources available in each habitat.
• Types:
  • Anadromous Fish: These fish spend most of their lives in the ocean but return to freshwater rivers and streams to spawn (release or deposit eggs).
    • Examples: salmon, trout, and shad.

• Catadromous Fish: These fish spend most of their lives in freshwater but migrate to the ocean to spawn.
  • Example: Eel

Why in News?

Recently, a study discovered an ancient Nile river branch that helped transport workers and materials to Egypt's pyramids, now buried under modern landscapes.

• Researchers employed technologies including satellite imagery, high-resolution digital elevation data, and historical maps to trace the path of the now-vanished Ahramat Branch of Nile River.

What are the Key Highlights of the Study?

• The revelation of the Ahramat Branch, a previously unknown Nile channel from Lisht (village) to Giza (city), illuminates its crucial role in transporting workers and materials for pyramid construction, offering insight into their geographic and logistical considerations.
• The study shows that natural events such as climate change, tectonic shifts, and human activities, along with environmental factors like desertification and changes in rainfall, have altered the Nile's landscape, and branches over time, impacting the region's ecology and water systems.t.

What are Key Facts About Egyptian Pyramids?

• The pyramids of Egypt are massive, ancient stone structures built as tombs for pharaohs (ancient Egyptian rulers) and important figures during the Old Kingdom (roughly 2700–2200 BCE) and Middle Kingdom periods (2050–1650 BCE).
• There are over 118 identified pyramids in Egypt, but the most famous are the three pyramids at Giza:
  • Great Pyramid of Giza: The oldest of the Seven Wonders of the Ancient World and the largest pyramid ever built. It was constructed for Pharaoh Khufu (Cheops).
  • Pyramid of Khafre (Chephren): This pyramid appears larger than the Great Pyramid due to its steeper angle and the presence of the Sphinx, a massive statue with a human head and a lion's body, located nearby.
  • Pyramid of Menkaure (Mycerinus): The smallest of the three main pyramids at Giza, built for Pharaoh Menkaure.

World's First Wooden Satellite

Carnian Pluvial Episode

Source:TH

The Carnian Pluvial Episode (CPE) was a period of extended and intense rainfall that occurred in the late Triassic Period (approx. 230 million years ago).

• It had a significant impact on the evolution of both terrestrial and marine life.
• Researchers believe that this prolonged rainfall was the result of global climate change caused by extensive volcanic activity in the Wrangellia Province (located in western coast of North America).
• During the late Triassic period, all of the Earth's landmasses were joined together to form one large supercontinent known as Pangaea.
• Impact of CPE:
  • It caused mass extinction of marine life and terrestrial species, wiping out about one-third of all species and leading to a decrease in biodiversity.
    • However, it also created an opportunity for new and different marine and terrestrial species to evolve, including the rise of dinosaurs .
• The CPE is believed to have set the stage for the Mesozoic Era, known as the age of the dinosaurs, in which dinosaurs emerged and flourished, dominating terrestrial ecosystems for the next 150 million years.
