Question

currently, new regulations control the use of pesticides and chemical fertilizers to reduce what? (1 point) water contamination insect population crop sizes illness

Explanation:

Pesticides and chemical fertilizers can seep into water sources, causing water - contamination. New regulations aim to reduce this environmental hazard. Insect population is not the main target for reduction by controlling these substances in this context. Crop sizes are not reduced by regulating pesticides and fertilizers; rather, they can be managed for better and more sustainable growth. While illness can be a consequence of water contamination from these substances, the more direct reduction target is water contamination itself.

Answer:

Water contamination
