Nature is everything for living being,all the living being inhabiting this earth,trees are out best friends,mother nature,in her infinite wisdom,has gifted them to man  to live in  harmony within and to be great service to him.

Besides fruits,tree provide important raw materials for our industries,the wood for furniture,housing come from trees.

In fact,the nature giving us so many things for living on earth and it already gives comfortable life for us but now a day we are destroying them one by one for the perpuse of experiments and showoff,in case each human being planting four trees the earth again converts into green and there is no problem of oxygen.

On this covid-19 pandemic period we the people are facing a lot of oxygen problem and so many people's lost their life due insufficient supply of oxygen cylinders at hospitals and this is so crucial situation for human being and I think this curse of nature on human being.

So according to my opinion each person just planting four tree around our home can help to improve the oxygen concentration on earth and it can also help to stop the soil erosion and helps to increase the effective fertility of soil for agriculture.

Nowdays Almost 30 percent of oxygen produced in atmosphere can by industries and around 10 percent of oxygen can used by major cities of country and remaining only can good for breathing and its not info for human being and major problem for destroying the Forest is to development of cities and in the name of bridge construction,highways,etc.

And even some many trees are cutted in the name of smart city development.

Another main resources for leading the life is water we can't leave without water it is very essential for us and on this earth 70% of water and remaining 30% of land is land will acquired and in 70% of water it will again divided into 58% of ocean water and it can't to drink perpuse and remaining only for drinking water.

Natural resources are resources that exist without any actions of humankind. This includes the sources of valued characteristics such as commercial and industrial use, aesthetic value, scientific interest and cultural value.On earth, it includes sunlight,atmosphere, water, Land, all mineral's along with all vegetation, and animal life.resurces can be part of our natural heritage or protected in Nature reserve.
