For the last a few years global warming became one of the biggest problem in the world. Development of industry, rising number of cars, uncontrolled usage of natural sources are main reason of this situation. During last decades a very fast growing of human populations also happened. All above caused that temperature on earth started rising. Ice on many areas such as: Antarctica, Arctica and glaciers in mountains started to melt. Some countries and especially islands have now problems with rising level of seas and oceans. Every one can start to protect environment by: saving energy, sorting rubbish, using pro ecological equipment, etc. It’s still not too late.
