On 22nd April is celebrated the Earth Day. But there isn't reason to party! Our planet is undergoing changes that I am afraid of, like global warming, that can bring serious consequences for the whole planet - including plants, animals and humans. The retention of heat in the land surface can strongly influence the system of rainfall and drought in several parts of the world, affecting plantations and forests.
Some forests may suffer process of desertification, while crops can be destroyed by melting of the ice. The result is the migration of animals and humans, scarcity of food, increasing the risk of extinction of many animal and plant species, and increase in the number of deaths from malnutrition.
Another big risk of global warming is the melting of the plates of ice of Antarctica. This melting have been happening for thousands of years by a slow natural process. But the action of man and the greenhouse effect accelerated the process and become unpredictable.
Global warming also brings climate change, which is responsible for 150 thousand deaths each year worldwide. A heat wave which hit Europe in the summer killed at least 20 thousand people. The tropical countries and the poor are the most vulnerable to such effects.

It is not enough just to be afraid. We must save the planet. Make your part and have reasons to celebrate this day!
