Everybody knows that the worst environmental problem is the Global Warming. It´s amazing how far we´ve come. We prefer all the technologycal advances in exchange of the destruction of our planet. People haven´t notice how in danger we are. Since centuries ago, we´ve been constructing a fatal future to ourselves and to the earth and if we don´t change our ways before we even know it it will be too late to fix all the damage we´ve done.
So...what can we do about it? 1)Stop using the familiar incandescent light bulbs and replace them with compact fluorescent bulbs, which last much longer and use only a quarter of the energy consumed by conventional bulbs
2)when shopping for an appliance (a refrigerator, a dishwasher, an air-conditioner)select the one with the highest energy efficiency rating
3)turn off the light when you are not using it.
