What will happen if there are no tree on the earth?

Trees continuously supply a huge amount of oxygen required for our breathing. Without trees there will be no oxygen and we cannot breathe without oxygen. All living organisms will die if there is no tree on earth. No tree means no life.

The amount of carbon dioxide will increase- the tree absorbs carbon dioxide during photosynthesis and converts them into oxygen, therefore this will help the living things like us(man) and animals to get more oxygen.2. The Earth will be hotter.- during the hot weather, transpiration on the surface of the leaves will occur. during transpiration, water in the form of vapour is given out and this will eventually increase the humidity of the air and tend to be cooler.Trees are one of the sources of water vapour that is found in the air .They release water vapour through transpiration.If there are no trees,this water source will be cut off reducing the average rainfall of the earth.Secondly,they absorb CO2 and release oxygen.If no trees are there, oxygen content in the air may come down gradually leading to death for want of oxygen.Further CO2 content in the air will increase leading to global warming and producing extreme weather conditions.Tree's root protects the soil and prevents it from soil erosin and weathering.So soils are able to retain water and never become dry sands as in the desert.Life will absolutely end, because trees balance oxygen,carbon dioxide gases in atmosphere and perform the circulation of very valuable elements and minerals in the world which includes sensitive balance systems called ecological balance. And also trees protect grasses, bushes and ensure as sheltering microlife such as insects and birds..Humanity would die due to lack of oxygen, unless we found away to make our oxygen. Also we would have never existed in the first place as we would of died long back due to lack of fire, shelter and basic hunting equipment.There would be no oxygen,no paper,no eraser and the whole earth became a desert every thing will die.

our all neccessities are depandent on trees .if there are no trees we cannot live as there will be no oxygen left and no other material for building homes. there would be no rains .the weather would not be under controletc.
