Question

question 1 of 25 which of the following is a cost of recycling aluminum?
a. preserving earths remaining aluminum reserves
b. disrupting tropical rain forest plants and animals
c. using energy to transport a heavy metal
d. producing toxic waste products

Explanation:

• Option A: Preserving aluminum reserves is a benefit of recycling, not a cost.
• Option B: Recycling aluminum doesn't typically disrupt tropical rainforests (mining bauxite for new aluminum might, but not recycling).
• Option C: Transporting aluminum (even recycled) requires energy, which is a cost associated with the recycling process (e.g., moving recycled materials to processing facilities).
• Option D: Recycling aluminum generally produces less toxic waste than primary production; primary production (extracting from bauxite) is more likely to produce toxic waste, not recycling.

Answer:

C. Using energy to transport a heavy metal
