C. eliminated diseases by killing mosquitoes and flies
D. caused biological hazards

Answer 1

The widespread use of insecticides has caused imbalance in the relationship between living beings and their environment.

• Although modern technology has made lives a lot easier but it is causing disruption in the natural working of the environment.
• The use of insecticides kills insects. As a result, food chain of which these insects were a part of will be disrupted. This will result in an imbalance between other species of the food chain also.
• Hence, the widespread use of insecticides might be useful for humans to save their crops but it causes an imbalance between living beings and the environment.
