Question

What adverse environmental and human health effects can occur as a result of pesticide use?

Short answer

The adverse effects of pesticides can lead to a reduction in biodiversity, water pollution, soil degradation, and harm to human health including neurological problems, cancer, and hormonal disruptions.

Step-by-step solution

Understand Pesticide Function

Pesticides are substances used to control or kill pests, including insects, weeds, and diseases. They are often used in agriculture to maximize productivity by reducing pest-related damage to crops.

Exploring Environmental Effects of Pesticides

Pesticides can have numerous negative effects on the environment. These include: (1) Reduction in biodiversity: as pesticides can wipe out non-target species reducing the overall biodiversity of an ecosystem. (2) Water pollution: Pesticides frequently seep into ground and surface water systems, which can subsequently impact aquatic life. (3) Soil degradation: Many pesticides can reduce soil health by killing beneficial soil-dwelling organisms.

Exploring Human Health Effects of Pesticides

Exposure to pesticides can cause various health conditions in humans, primarily through accidental ingestion, inhalation, or direct skin contact. Some potential health issues include: (1) Neurological problems: as some pesticides may harm the nervous system. (2) Cancer: Certain pesticides have been linked to several types of cancer. (3) Hormonal disruption: Some pesticides may interfere with the human endocrine system. These harmful effects can depend on the duration, frequency, and level of exposure, in addition to the specific type of pesticide.
