Regular landfills don't look any prettier than heaps of electronic junk. As the furnaces burn off what they can (depositing harmful chemicals into the air as they do so), the rest of the waste just clutters around them, covering vast distances and effectively creating a trash city. Very little waste of this kind biodegrades, and if it does, it takes hundreds or even thousands of years. We as a species create such a tremendous amount of waste, and yet we do so little to clean it up.
This picture was taken in Bangladesh, where the waste is particularly bad, but there are a number of other countries where identical images could have been taken. It says something about us as a species that we burden developing nations with the task of hosting and disposing with waste on this scale; such a site would be unlikely to be permitted in most of America or Europe.
