the earth is blue like an orange

Some countries, preoccupied with the global warming caused by the excessive emissions of carbon dioxide, decided to use bio fuels instead of  diesel made with petrol. The bio diesels are less polluting that the normal ones. In Brazil, for instance, the cars run on sugar cane alcohol. But I think the bio fuels will not solve the question of global warming. The many fields that are used for sugar cane plantation could served for growing foodstuffs for people and corn for the animals.

Electric cars can’t neither be a solution. I remember of a Spanish, that was complaining because the numerous aeolian windmill disfigured the landscapes of his country. The problem with electric cars is the production of electricity.

In fact, I think all the renewable energy sources that are proposed for the transportation won’t solve anything. The real problem is our behaviour. How many businessman go to work alone in their car? We should developpe public transportation, like buses and subway, and optimize the private transportation, trying to use all the space we can in the cars. We could easaly divide by two the carbon dioxide emission caused by transportation. All we need is to act; if everybody do something, we could  limit the problem.

“World Looks to Ethanol to Ease Fossil Fuel Dependency”, on the newspaper Voice ofAmerica: an article about Bush Latin America tour. The brazilian mostly disapprove this trip, whose objective was to discuss ethanol (sugar cane alcohol) with president Lula.
