Question

how does the use of insecticide and chemical fertilizers cause water pollution?​

Answer 1

Environmental pollution is a significant problem. But while most of the focus is placed on polluting industries, toxins like mercury and small particle traffic pollution, a major source of environmental devastation is caused by modern food production. Far from being life sustaining, our modern chemical-dependent farming methods:

 - Strip soil of nutrients
 - Destroy critical soil microbes
 - Contribute to desertification and global climate change, and
 - Saturate farmlands with toxic pesticides

⚫Insecticides and chemical fertilizers contain salts which are water soluble.

⚫They get dissolved in water and seep underground.

⚫Here they get contaminated in ground water and thus cause pollution.
