Our world needs a healthy environment to nutrify the life on the earth. The things that we need to be alive are air, water, plants, lands, forests, animals, etc which are the part of the environment. We can't live a second without these things. We are fully dependent on the environment. But we are the main cause of destruction of the environment. Each and every day intentionally or unintentionally we are doing damages to the environment. Not a single substance is now healthy for us. Pollution is appearing in everywhere like air pollution, water pollution etc. Forests are burning, glaciers are melting due to global warming. If the condition of the environment deteriorating day by day then we also would not stay healthy. Therefore we have to take some initiative to protect our environment from damages. We have to raise awareness among the people. We have to plant more trees and prevent cutting down of trees. Tree plantation is important to keep our environment healthy. Trees not only absorb carbon dioxide it also inhales many harmful gases like carbon monoxide, etc. Trees filter the polluted air and give us the purified air without any cost. Nowadays many products like air purifiers are selling in the market. It consumes both money and electricity. But if we take a little effort to plant trees around us, it will provide fresh healthy environment for a large number of people without any cost. Trees also provide foods for birds, animals and human beings and it provide shelter too. If we cut a big tree, many birds will lost their shelter. Trees also keep the environment cool. Nowadays global warming is appearing in a alarming rate. Temperature is rising day by day. Summer is now unbearable for all living beings. And the underground water level is also decreasing in many areas. Only trees can help us to preserve underground water and keep the environment cool. If you see anyone is cutting down a tree tell him/her to plant a new one or you can also plant there a new one. And without buying artificial trees to decorate your home please plant real trees which is less costlier and will need little effort.
