Question

Answer 1

It doesn't make land, water or air dirty or unsafe to use. It does not cause disease. ... They play no role in regulating the planet's atmospheric temperature. But carbon dioxide and other trace gases in the atmosphere do absorb the outgoing long-wave radiation.

Answer 2

Answer:

$CO_2$ acts as a greenhouse gas because it traps the heat in the earth’s atmosphere and maintains the temperature for living organisms to survive.

Explanation:

Greenhouse is an effect in which the sun heats the earth's surface during day time by their radiation and in the night when this radiation released from the earth surfaces the surrounding gaseous environment holds this heat and maintain the temperature.

This effect is important for the comfortable survival of the organisms. $CO_2$ gas holds this heat in the gaseous environment and made the temperature warm. This happens because $CO_2$ is the highest concentration among all greenhouse gases.
