Name an industry which can cause both air and thermal pollution and as well as eutrophication.

The fertilizer industry can cause both air and thermal pollution and as well as eutrophication because:

i) The exhaust from the fertilizer industry consists of gases such as Carbon monoxide, carbon dioxide, sulphur oxides and particulate matter. This causes air pollution.

ii) The effluents released into water bodies from the fertilizer industries causes the degradation of water quality by changing the temperature of water. This causes thermal pollution.

iii) These effluents contain nutrients like Nitrogen, Potassium, phosphorus, etc. enhances nutrient richness of the water body which causes excessive growth of algae. This causes Eutrophication.
