Question

what is one of the primary benefits of recycling aluminum cans? it creates more greenhouse gas emissions. it increases the weight of the waste stream. it decreases energy efficiency in production. it reduces the need for raw material extraction.

Explanation:

Recycling aluminum cans reduces the need for raw material extraction. Recycling conserves natural resources. Creating new aluminum from recycled cans uses less energy than extracting from bauxite (raw material). It also lowers greenhouse gas emissions (contrary to first option). Increasing waste stream weight (second option) is incorrect as recycling reduces waste. Decreasing energy efficiency (third option) is wrong; recycling improves it.

Answer:

It reduces the need for raw material extraction.
