Today is the World Environment Day. Everyone around you including TV and Radio would talk about environment topics. You would listen same type-cast suggestions like ''Save Trees", "Save Earth" and "Save Water" etc. Anyone ever cares a little for nature or earth on other days than Environment Day?
There are many solutions for saving environment and nature. But only bit of them are practically possible. We can't go to office on bicycle alone. It should be joined by other people of the city or country. Solar energy can reduce our dependent on electricity. But the technology itself is very armature. The setup to get Solar energy is costlier than amount of energy we get. It is same in using Biofuel and Hydrogen as fuel for cars.
