Question

Ecological imbalance in the biosphere is created by
A. Cutting of forests
B. Conservation of forest
C. Production of more plastics
D. Both A and C

Answer 1

Hint:- Biosphere, a comparatively thin, life-supporting stratum of the surface of the Earth that ranges from a few kilometres into the atmosphere to the ocean's deep-sea vents. The biosphere is a global ecosystem made up of living organisms as well as non-living things from which they derive the resources and nutrients.

Complete Answer:-
To accommodate rural, commercial or municipal use, deforestation is done which involves the felling and clearing of forest cover or tree plantations. To make the land available for domestic, business or industrial uses, it requires a permanent end of the forest cover. Deforestation can also be seen as the destruction of trees, resulting in many environmental and biological imbalances. Synthetic products are created by chemical methods that are artificially produced by chemical synthesis, such as plastic bags, tables, toys, etc. Such synthetic materials can survive for years and decomposers can not decompose them. Like numerous consumer products, these synthetic products are made of plastic; man's existence hinders the flow of materials in the biosphere. Improper disposal of synthetic products is one of the reasons as well as the cause of ecological imbalance. It destroys the ecosystem which causes the death of many species, at the same time, creates different issues such as pollution in the living world.

Therefore the correct answer to this question is option D.

Note:-
Four main factors responsible for an ecological imbalance in India are:
1. Degradation of Land and Soil Erosion
2. Environmental Problems from Faulty Mining Practices
3. Faulty Utilisation of Water Resources
4. Deforestation.
