There are new technologies now that allow us to reduce CO2 and other pollutants while continuing our everyday routines to work or school. This new technology is fuel cells and cars that run on hydrogen.
These cars emit no greenhouse gases, just water vapor, and do not use a combustible engine. Instead they run on fuel cells. These fuel cells convert the hydrogen into electricity.
The advantages of hydrogen are huge: no more smog-forming exhaust gases, no more carbon dioxide emissions that contribute to global warming, no more worries about diminishing oil supplies and rising prices. The same amount of hydrogen will take a fuel cell car at least twice as far as one with a converted internal combustion engine. http://www.science.org.au/nova/063/063key.htm
The hydrogen-powered Mini concept was unveiled at the 2001 Frankfurt Motor Show. It runs solely on hydrogen and shows the potential for a virtually zero emissions vehicle which still offers an outstanding performance. The BMW Clean Energy system involves liquid hydrogen produced from water using solar power. Hydrogen as a motor fuel is the answer to many environmental problems since there are no harmful emissions, no depleting of resources, and no danger to the atmosphere. The result of their research is the new BMW 750hL hydrogen powered vehicle.
The heart of the 750hL is a hybrid, 12-cylinder combustion engine with two independent electronically controlled fuel induction systems. These systems allow the 750hL to run on either gasoline (petrol) or hydrogen. Electricity generated from solar power is used to split water into hydrogen and oxygen. Oxygen is released into the atmosphere, while hydrogen is liquefied and stored at a very low temperature (-253 °C). During internal combustion, the hydrogen combines with oxygen. The resulting energy powers the vehicle, while the hydrogen is returned to the environment as water. Harmful emissions are virtually eliminated.
By cooling hydrogen to -253 degrees Celsius, hydrogen is shrunk to a thousandth of its original volume. 70 layers of aluminum and fiberglass sheets between the exterior and interior vehicle walls insure that the liquid hydrogen remains at extremely low temperatures. The car gets electricity from a newly developed fuel cell battery that converts hydrogen into electric current, and because it has several cells in series, it supplies enough power to keep the climate control running even when stationary. Working with Shell Oil Company, BMW has developed a technology for dispensing hydrogen from a filling station's pumps into a car's fuel tanks. The world's first fully automatic hydrogen filling station was opened in May 1999 at the Munich Airport. In the market for a new car? Here are a few you can to add to your search...

With all this talk about pollution, it can get overwhelming and we lose sight of what it is we can do, as an average person, to make a difference.
