One fourth of area is covered by land is Called Land.
Land is a earth which is occupied by people for shelter,occuption etc..,

We can classify major sources that lead to land following Categories
Mining and quarryingSewage wasteHousehold Garbage Industrial Waste

Despite the Advantage of nuclear as a clean energy, the big concern is the resulted from nuclear reaction, which is a form of pollution called Radio activity.
Radiation (Laser-Rays) will from Radio Active Pollution.
