There are a lot of concerned people, about the environment that is.  That they take the global warming issue seriously.  They promote it and act on it.  They say that fossil fuel use they say is the main cause of our atmosphere depletion.  That is why other car manufacturer are making their new cars eco-friendly.  They use electric cell, biodiesel and water as their source of fuel. 

I think that biodiesel is widely used and accepted.  How To Make Biodiesel is also, I think much more easier and cheaper to produce.   There are source material on the internet on how you can make it.  Complete with guide and pictures showing the steps in making them.  I even saw a tv special about it. He collects used vegetable oils and processed them in his own house and he uses it.  So if we really believe that glabal warming is happening, which it is. We should do something about it and let’s not just wait for someone to do it for us.
