dimaraw [331]

Answer:

<em>The overuse of pesticides</em>

Explanation:

Pesticides are usually sprayed on plants so that the pest organisms can be killed. But these chemicals sprayed on plants can be toxic for humans when humans consume crops which have been sprayed with pesticides. Also, erosion causes these toxic chemicals to get eroded in the nearby lakes. The chemicals in the pesticides are harmful for every life that uses this water. Hence, the overuse of pesticides might kill pests but it is also toxic for consumption by humans.
