Soil

Soil can become contamined as a result of industrial waste. Much domestic rubbish is disposed of in landfills. Waste disposal should should be controlled and maintained properly. Waste can be reduced in a few ways:
• before the waste is landfilled, it can be shredded or compressed in order to reduce its volume
• landfill can be avoided by
• re-using
• recycling
• energy recovery
A great deal of industrial waste has been reclaimed. Not only bottle bins or containers, but also can,
plastic and paper containers should be installed where the public can deposit used glass, cans, plastic
and waste paper for recycling.
• domestic rubbish should be sorted out, too. Kitchen garbage and garden waste of organic origin should be composted and turned into fertilizer
• Organic waste in landfills can be re-used in the form of biogas which comes from natural decay
• People shouldn't litter and the law should be stricter to those who break the rule.

Land can be also contaminated by radioactive substances. More than 80% of radiation the public is exposed to comes from natural sources. Only about a thousandthcomes from the disposal or discharge of radioactive waste.
• Strict controlls should be placed over the storage, use and disposal of radioactive substances
• Spent nuclear fuel should be stored in concrete blocks for at least 50 years to allow the heat and radioactivity to decay.
• People should be aware of naturally occurng radon gas.
