Fossil fuels like coal and oil, when burnt, produce a substantial amount of ash in the atmosphere. The particles which contain toxic chemicals when mixed with water vapor result in acid rain.

Chemical fertilizers and pesticides are used by farmers to protect crops from insects and bacterias. However, when these chemicals are mixed up with water, they produce harmful pollutants for plants and animals.

The element that is used in the production of nuclear energy is Uranium, which is a highly toxic chemical. When it was mixed up with water that time it causes very serious hazards.

Transportation of coal and other petroleum products through underground pipes is well known. Accidental leakage may happen anytime and may cause damage to the environment and result in soil erosion.

The increased level of nutrients in water bodies is known as Eutrophication. It results in the bloom of algae in the water.

It also depletes the amount of oxygen in the water that negatively affects fish and other aquatic animal populations.

The garbage produced by households in the form of paper, plastic, food, aluminum, rubber, glass, is collected and dumped into the sea in some countries.

Mining is the process of crushing the rock and extracting coal These elements, when extracted in the raw form, contain harmful chemicals which was mixed up with water.

Industries produce a tremendous amount of waste, which contains toxic chemicals and pollutants.

Many industries, not having a proper waste management system, drain the waste in the freshwater, which goes into canals, rivers, and later into the sea.
