Global Warming

Nowadays as you know, there is a lot of pollution in the atmosphere. The level of carbon dioxide and other such gases (known as greenhouse gases) is rising. These gases trap the heat and do not let it escape from the atmosphere.

When the presence of these gases goes beyond a level, the temperature rises. This happened to planet Venus and today, it has deadly clouds of carbon dioxide. Its atmosphere is blazing hot.

This can happen to Earth and if it does, the heat will melt the polar ice caps, causing flooding around the world. Already the temperature is rising by 1 degree C every year. Unless we do something, the Earth is doomed.
