Card 4
Question: How do greenhouse gases cause warming?
Answer: Gases like carbon dioxide, methane, and nitrous oxide trap heat in the atmosphere, acting like a blanket.
Card 5
Question: What role does burning fossil fuels play in environmental pollution?
Answer: Burning coal, oil, and gas for energy, transport, and industry releases large amounts of CO2 and N2O, contributing to greenhouse gas emissions and air
Card 6
Question: How does deforestation contribute to climate change?
Answer: Cutting down trees reduces CO2 removal by vegetation and releases stored carbon, increasing atmospheric CO2.
Card 7
Question: How does agriculture contribute to greenhouse gas emissions?
Answer: Livestock farming and certain farming practices increase methane (CH4) and nitrous oxide (N2O) emissions.
Card 8
Question: What ecosystem impacts result from climate change?
Answer: Habitat loss (sea-level rise, wetland loss, desert expansion), biodiversity loss (species extinctions, coral die-offs), and more frequent/intense extr
