Global warming

First of all we need to define what is global warming? Global warming is the increase in the average temperature of the earth. Of course we are the guilty of this and global warming brings inconvenient effects for us.

We have to quote the causes of global warming to understand how it started. With this it will be easier to understand it growth. The major cause for me it will be the green house effect. The green house effect starts when the sun raises rich the earth and provide us heat.

But this heat have to go away, what happens with the green house effect is that thanks to the companies, cars, and all kinds of machines that release this gases: nitrous oxide, sulfur hexafluoride, hydro fluorocarbons, per fluorocarbons for example make that this heat never leave and stays at earth. So the earth continues and continues absorbing heat without releasing it.

The worst effect of global warming for me is the constant rise in the sea level per year in consequence to the ace melt on the poles. But this is not the only effect of global warming. In the camp of agriculture the intense heat can become the loss of crops, and this crop is our food. The effects are like a chain so if a link is broking all the chain loses its purpose.

Is urgent for our safety to star to use green products, use transportation that do not contaminate. Every problem has its solution, so we have to start to think in our future, the future of our sons, and the future of the earth. We need to act now that we still have time.
