The greenhouse effect helps to maintain a certain temperature level on the Earth’s surface, making it habitable for the living beings.
The greenhouse gases help block the harmful solar radiation from reaching planet’s surface. These gases work like a filter and bounce back most of the unwanted and damaging energy into space.
Ozone, which is one of the crucial greenhouse gases, absorbs the harmful ultra-violet (UV) rays of the sun. If there wasn’t any Ozone layer in our atmosphere, the UV rays could reach the surface directly and affect the life on earth on a massive scale causing cancers, sunburn, damaging immune system and eyes.
