Each time you throw something as garbage, think of where it will finally end up. Whether it is a plastic glass, your broken cell phone or the used up battery cells from your portable CD/MP3 player, they all contribute in some way to environmental pollution and are also hazardous to life. Not only are they biodegradable, but also disposing of them has their own risks as they release harmful toxins into the air and surrounding soil and ground water.
This website provides a good glossary of technical terms used in this field. It explains in simple terms how waste accumulation affects the environment as hazardous substances, increases toxicity and ways in which the waste recirculates in the air and water, causing serious harm to humans and other life.
Apart from solid natural waste, there are other types of man-made wastes that are more hazardous to the environment. Cell phone, for instance are made of lead, mercury and plastic and so many millions of them get thrown as garbage. This kind of electronic garbage creates environmental problems.
Electronic waste is fast becoming a big threat to our environment. Visit this website to know in what way they contribute to environmental pollution. This report has technical terms that are explained. It also has some unknown but threatening facts such as the harmful effects of the fire retardant being used to protect PCs and electronic appliances against fire.
Another problem is the fact that disposing of the junk is hazardous. For example, mercury will leach when certain electronic devices, such as circuit breakers are destroyed.
Batteries are an environmental hazard. The acid leaches not only into the soil but also goes into the ground water. Disposing of them also creates their own problems as the lead is likely to remain in the ash and be released in the air.
As the problem of waste accumulation reaches threatening proportions, a worldwide effort is on to control waste and to manage it. Many countries and individual towns are making an effort in their own way to manage waste. Visit this site to know more about such efforts.
