Question

observation of harmful effects of chemical fertilizers​

Answer 1

Explanation:

Chemical fertilizers have aided farmers in increasing crop production since the 1930's. ... Some of the harm chemical fertilizers may cause include waterway pollution, chemical burn to crops, increased air pollution, acidification of the soil and mineral depletion of the soil.

Though chemical fertilizers increase crop production; their overuse has hardened the soil, decreased fertility, strengthened pesticides, polluted air and water, and released greenhouse gases, thereby bringing hazards to human health and environment as well

When the excess nutrients from all the fertilizer we use runs off into our waterways, they cause algae blooms sometimes big enough to make waterways impassable. When the algae die, they sink to the bottom and decompose in a process that removes oxygen from the water

Chemical fertilizers contain phosphates, nitrates that can actually be the main reason behind water pollution. Environmental nitrogen and phosphorous contribute to the process of Eutrophication, which enriches the water surface with nutrients. ... The effect of Eutrophication is that there is an abundance of algal bloom.
