Ans: Various global environmental issues include:
- Climate Change: Rising temperatures, sea levels, and extreme weather due to greenhouse gas emissions.
- Deforestation: Large-scale removal of forests, leading to habitat loss and reduced carbon storage.
- Loss of Biodiversity: Species extinction and ecosystem degradation due to habitat destruction and pollution.
- Pollution: Air, water, and soil pollution from industrial, agricultural, and urban activities.
- Water Scarcity: Insufficient access to clean freshwater for drinking and agriculture.
- Ocean Acidification: Increased CO2 in the atmosphere is absorbed by oceans, causing harm to marine life.
