Multiple choice

What are the major environmental impacts of food waste?

  1. Greenhouse gas emissions

  2. Water pollution

  3. Deforestation

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Food waste contributes to greenhouse gas emissions, water pollution, and deforestation. Decomposing food in landfills releases methane, a potent greenhouse gas. Food waste also contaminates water sources and contributes to the eutrophication of water bodies. Additionally, the production of food requires significant land and water resources, which can lead to deforestation and other environmental issues.
