Importance+of+Energy+to+Humans

=﻿Importance of Energy to Humans= Energy is extremely important to humans, energy is the ability to do work produce light movement and heat. It allows us to live, the sun (the main energy source) gives the plants and trees heat which helps them grow. Let's face the facts; the human and animal race could not exist if there were no trees. In one season a mature leafy tree produces as much oxygen as 10 people inhale in a year.

Energy is also important to humans as it has taken us from transportations such as horseback, where the energy is coming from the sun to transportation like aeroplanes and helicopters, where advanced technology has got energy from other sources such as oil and gas.

However the human race is using alot of non-renewable energy sources, which are slowly ruining our planet. We need to start using alternative energy.
