• Released on February 26, 2025, by the Centre for Science and Environment (CSE) and Down To Earth (DTE), the State of India’s Environment 2025 report offers a comprehensive analysis of the country’s environmental challenges
• Focus Areas: Climate change, air and water pollution, waste management, biodiversity.
• Special Topics: Plastics, antimicrobial resistance, Thar desert, 40th anniversary of Bhopal Gas Tragedy, India’s renewable energy targets.
• 2024 Environmental Challenges:
• Extreme Weather: 255 out of 274 days had extreme weather events, impacting 3.2 million hectares of cropland.
• Impact on Future Generations and Climate Change:
  • Generation Alpha, the youngest cohort, is poised to inherit a warmer planet.
  • The year 2024 was recorded as the warmest on record, with global temperatures rising 1.5°C above pre-industrial levels.

Answer: B

• A study published in October 2024 analyzed 203 black plastic products (e.g., kitchen utensils, takeout containers, toys) sold in the U.S.
• Source: Black plastic is often made from recycled electronic waste such as computers, TVs, and household appliances.
• Toxic Substances: Electronics contain harmful substances like bromine (a flame retardant), antimony, and heavy metals (lead, cadmium, mercury). These chemicals are toxic at high exposure levels and have been banned in many countries.
• Health Risks: The study found black plastic products contained decabromodiphenyl ether (BDE-209), a flame retardant linked to health risks, which was phased out in the U.S. over a decade ago.
• Study Findings:
  • Recommendation: Researchers advise against discarding all black plastic products immediately. Instead, continue using items until they are no longer usable, rather than replacing them prematurely.
  • Recycling Challenge: Black plastic that cannot be recycled should be handled appropriately to prevent further environmental harm.
