Question

what are the harmful effects of industries on the environment? explain these effects and suggest ways to prevent them.​

Answer 1

Explanation:

Some harmful effects of agricultural practices on the environment are:

i) Soil: Fertilizer added to soil not only changes the chemistry of the soil but also kills many useful microbes.

(ii) Ground water: A part of fertilizer always leaches down into soil and reaches ground water.It raises the salt content of ground water.

(iii) Eutrophication: Run-off from fields sprayed with fertilizer reaches water bodies.It results in their eutrophication.

(iv) Pesticides: Pesticides sprayed over crops reach water bodies killing the biota. Persistent pesticides undergo biomagnification and prove highly harmful to higher organisms.

(vi) Ground water: Continued use of ground water in agriculture has resulted in lowering of water table at most of the places.

(vii) Irrigation: It causes water -logging and salivation of soils.

(viii) Genetic Erosion:Use of only selected high yielding varieties has resulted in genetic erosion of the crop plants.

(ix) Damage to Nature. Natural ecosystems and habitats have been damaged during clearing land for agriculture.

Answer 2

Industries interrupt the natural flow of the ecological processes and disturb the environmental balance.

Explanation:

1. Industries cause pollution, resulting in deforestation, and endangerment of the habitat of many organisms who are important part of the environmental cycle.
2. All the negative effects of industries can be seen in the form of endangering of some species, and the bad condition of the forests, forest fires, reducing forest cover, etc.
3. The effects cannot be prevented but the same effects can be prevented from getting repeated in another area.
4. The industries should try to reduce the generation of toxic gases, treat the byproduct of chemical processes before dumping them, etc.
