Question

Which human activity would most likely have a positive impact on the environment? Using pesticides to decrease populations of birds of prey Increasing emissions into the atmosphere to decrease the pH of lakes Using parasites for biological control of pests to increase crop yields Engaging in uncontrolled hunting and trapping to reduce populations of carnivores

Answer 1

Using parasites for biological control of pests to increase crop yields is the human activity that would have the most positive impact on the environment.

Step-by-step explanation:

The human activity that would most likely have a positive impact on the environment is using parasites for biological control of pests to increase crop yields. This method of pest control involves introducing natural enemies, such as predators or parasites, that prey upon and destroy pest species. It is an effective and sustainable alternative to using synthetic chemical pesticides, which can harm non-target species and have negative effects on human health.
