Question

Which is not dangerous for life?

• A. Nuclear blast
• B. Deforestation
• C. Biopollutants
• D. Ozone layer

Answer 1

The correct option is D Ozone layer

A nuclear blast can cause the release of radiations which can cause cancer and the radioactive materials can lead to soil pollution.

Deforestation results in soil erosion and the quality of soil is degraded in which the plants cannot grow.

Biological pollution (impacts or bio pollution) is the impact of humanity's actions on the quality of the aquatic and terrestrial environment. Specifically, biological pollution is the introduction of non-indigenous and invasive species.

Ozone layer is present in the stratosphere over the Earths surface. This is a protective layer which prevents the entry of the harmful UV rays from the sun into the atmosphere.

Thus, the correct answer is option D.
