Sostenibility.

The natural resources that we need for to live, water, energy, wood, petroleum, oxygen, etc. they are every time more scarce and, if it follows like this, in the future, inexistent. What we can do? If everybody contribute in anything, the things would be very different. We only have to do little things for to have got a better world, we must promote the rational use of the resources: to recycle, to reuse, not to throw the rubbish, to spend the minimum, neither to open the tap nor switch on electrical appliance much time, to use the car the minimum, etc. and if it is possible to use renewable energy, extract to the water, to the air or to the Sun. If everybody to do one’s bit, we can achieve it. Is easy to get a better world, with the collaboration of every people.
