The primary environmental problem arising because of landfills is groundwater contamination from leaches. The toxic products in the landfills range from industrial solvents to household cleaners. Besides the chemicals from household and industrial products, electronic wastes contain lead, mercury and cadmium.
Answer:
Landfill sites are ugly. And it’s not just the eye sore of increasing piles of waste that’s the problem, landfills are landfill sites are bad for wildlife, nature, environment and global warminga major source of pollution, and there are many negative issues associated with them. Rubbish buried in landfill breaks down at a very slow rate and remains a problem for future generations.
The three main problems with landfill are toxins, leachate and greenhouse gases. Organic waste produces bacteria which break the rubbish down. The decaying rubbish produces weak acidic chemicals which combine with liquids in the waste to form leachate and landfill gas.
There are some secondary side effects as well: nauseous odors, unpleasant views, rat and seagull infestations, which create their own waste problems.
