After all, if we continue the trend that we have started of polluting and damaging the world around us, it may not be able to continue to provide us with the healthy elements we require for a healthy life. But solutions to the environmental issues are few and far between. Take our transportation situation, for example. We have become a society that is increasingly dependent on the use of cars to get around, as our world and neighborhoods have become bigger and more spread out. But cars are known polluters, and the cost of gas is beginning to limit the distances that we want to drive.

While this type of vehicle is very environmentally friendly because it produces almost no pollution, the fact that is must be recharged so frequently makes it a very inconvenient choice for many car owners.
