Question

The greenhouse effect is boon or bane? Give your opinion.

Answer 1

i. Greenhouse effect is responsible for the heating of the earth’s surface and atmosphere. Without the greenhouse effect, the average temperature of Earth would have been -18°C rather than the current average of 15°C. Hence, the greenhouse effect can be considered a boon for keeping Earth warm.

ii. However, increasing concentrations of greenhouse gases result in global warming which causes unfavourable climatic changes i.e., melting of polar ice caps. Hence, the greenhouse effect is also a bane. Thus, it can be said that the greenhouse effect is a boon only until the emission of greenhouse gases is kept under control.
