You probably heard about the greatest environmental threat of our time: the global warming. Maybe you think that your personal attitude and household consumption don't have such a big effect on our beautiful blue planet. You're right. But more people would change this situation. Now you think that you've heard it for thousands of times, and you know that other people think the same way and won't do anything to protect our planet. It's not your business, there are the green peace activists to solve this problem. But what makes you think that others don't try to change? Nowadays more and more articles and films deal with this topic. So, let's imagine that you are interested in the global warming problem, and you tend to take some steps. Like using carpool services.

A thick layer of atmosphere, which grows thinner further out into space, surrounds the Earth. The atmosphere is consists mainly of Nitrogen. 21% of the atmosphere is Oxygen while just around 1% of the atmosphere consists of other gases like Carbon Dioxide. When sunlight strikes the Earth, some of it escapes back into the atmosphere, but the presence of 'greenhouse gases' like carbon dioxide, nitrous oxide, methane, prevents all the radiation from escaping out into space. These gases trap the sun's radiation, heat and energy, and therefore, the Earth's temperature remains warm. So, more and more of the Earth's radiation gets trapped by the atmosphere and the Earth gradually gets warmer and warmer. It is believed that over the past century the Earth has grown warmer by around 1 degree F. This is called global warming, which occurs due to the greenhouse effect.
