Solutions
Despite the negative news, man has sought solutions to these problems. Technology has advanced in the sense of generating machinery and cleaner fuels or that do not generate pollution. Many cars are already using natural gas as fuel. In Brazil, for example, have millions of cars running on ethanol, not fossil fuels, which pollute little. Tests have shown that hydrogen in the near future, the cars can go with one type of fuel that releases in the atmosphere, only water vapor.
