QuestionAnswer What is the primary cause of climate change? The primary cause of climate change is the increased concentration of greenhouse gases like carbon dioxide and methane due to human activities such as burning fossil fuels and deforestation. Which gas is most responsible for the greenhouse effect? Carbon dioxide (CO₂) is the most responsible greenhouse gas for the greenhouse effect. What is biodiversity loss and why is it important? Biodiversity loss refers to the decline in the variety and variability of life forms on Earth, which is important because it affects ecosystem stability, resilience, and the provision of ecological services. Which renewable energy source is considered the most sustainable? Solar energy is considered the most sustainable renewable energy source due to its abundance and minimal environmental impact. What are the main effects of deforestation on the environment? Deforestation leads to loss of habitat, reduced biodiversity, increased carbon dioxide levels, soil erosion, and disruption of water cycles. What does the term 'ecological footprint' refer to? An ecological footprint measures the amount of natural resources and ecological services required to support a person, community, or activity. 5 Which international agreement aims to reduce global greenhouse gas emissions? The Paris Agreement is an international treaty aimed at limiting global temperature rise by reducing greenhouse gas emissions. What is environmental sustainability? Environmental sustainability involves using natural resources responsibly to meet current needs without compromising the ability of future generations to meet theirs. Which pollutant is primarily responsible for acid rain? Sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) are primarily responsible for acid rain when they react with water vapor in the atmosphere. What role do wetlands play in environmental health? Wetlands act as natural filters for pollutants, provide habitat for diverse species, control floods, and help in groundwater recharge.
