With over six billion people on our planet, resource stocks are already being depleted faster than nature can regenerate them.
As the world population increases to an expected nine billion by 2050, demands on resources will only get higher.
Saving the Earth's resources so that they are available for others to use for a long time into the future is therefore critical.
In order to do this we must change the ways in which energy is generated by using renewable energy sources, developing new technologies for cleaner and safer use and making laws so resources are used and managed better.
Renewable energy sources such as wind, solar, hydro, bio and geothermal come from supplies that should never run out.
In harnessing them to generate energy little or no damage is done to the environment.
