Soil
This is soil. We need soil to grow our fruits and vegetables. Soil also is important for the trees to provide us with oxygen.
Water and Trees
Water is needed for all life forms (humans, animals, plants and insects) to stay alive. Trees give us oxygen, fruit, heat (by burning the wood), shelter, cardboard and paper.
Oil
Oil is used to provide energy for transportation and heating. It is used for residential, commercial and industrial purposes.
