We eat fruits and vegetables. They all come from plants and animals. Plants survive with the help of water. Animals eat plants but need water too. Everything living in this world depends upon water.
Wood comes from plants so everything made from wood has used water.
This shows that water is a very important element we need to live. Nowadays, we use shortcuts to do everything. When the factory lets out smoke, part of it is chemicals. As we know, the smoke forms clouds. As a result when it rains we get acid rain which is very harmful.
