About Forest Destruction

Resently, I had an oppotunity to think about the groval warming and I studied about which is my best concern.
Forest accounts for 1/4 of the land all over the world but it is said that the forest will be districted completely after 100 years.
As one of the cause of the forest destruction there is commercial tree felling. Above all, Mangrove forest is given grate damage by it. Also the forest of mangrove in Kenya is reduced 2% of all every year.There is a big crisis for all lives so we have to protect the forest which produce us clear air, fresh water, fertile soil and so on. In some source, the causes of the forest destruction are these; mass deforestation for mass-use of woods, disappearance of virgin forests, deforestation for a pastureland or a large scale farm, development skiing ground or some leisure facilities, devastation of forests by the acid rain and drying up forests by the global warming.
To solve these problem, there is 4R; a movement put forward by Ms. Wangri, who is the vice-minister of Ministry of the Environment of Kenya and a prize winner of Novel Price Prize. 4R is a word included Refuse, Reduce, Reuse, Recycle. We can try this movement for our little intention to solve our forest, at once.
