Sustainable energies


SUSTAINABLE DEVELOPMENT
A few days ago it was published that in the world we are already 7,000 millions of people and as most of our planet resources are limited we have to take responsibility of our natural environment for the future.

Because of this it's essential that we all work to make sustainable development a reality, because if now we use the resources without wasting them we could use them for longer.

Things we can do to improve the future of the Earth:
- Plant trees.
- Promote the use of renewable energies.
- Save water 
- Prevent air pollution.
