(true or false) true false 21. recycling and composting of food waste in the cafeteria reduces water pollution since these do not go to the landfill. (true or false) true false

Explanation:

Question 19

Trash on parking lots and sidewalks is part of land pollution, and water pollution involves contaminants in water bodies. So this statement is false.

Sediments can cloud water, pesticides/fertilizers runoff, sewage has pathogens, and heat (thermal pollution) all harm waterways. So the statement is true.

Recycling/composting food waste reduces landfill waste, which can prevent leachate (polluted water from landfills) from entering waterways, thus reducing water pollution. So the statement is true.

Answer:

False
