It should be noted that conventional plastics can be made biodegradable with the inclusion of a small amount of an additive that promotes biodegradation. It is then called oxo-biodegradable plastic. Read more at http://biogreenproducts.com . Many plastic disposable products are being introduced that can be biodegraded using oxo-biodegradable technology.
From 2 Weeks To 5 Years.
Plastic does NOT biodegrade, because it is not make of organic matter. It simple breaks into smaller and smaller pieces of plastic until, after who knows how long, it is finally broken down to it's molecular level. The molecules eventually break down into atoms, and the plastic no longer is plastic. Look in any scientific book about plastic, and you will find this information...........

nonbiodegradable waste can last for hundreds even thousands of years.
A non Biodegradable plastic bag will decompose in 500 years
Hundreds, 400-700 I think, but I'm not certain, landfill sites do not provide good conditions for nonbiodegradable plastics to degrade,
A fewv years if you dont waste it
Biodegradable substances are waste substanses that can decompose after a peirod if time whether short or long e.g basically food, paper, etc While non biodegradable substances are waste products that can not decompose even after a long period of time e.g glass, metal cans, cups, plastic and the have to be recycled.
Non-biodegradable substances can last forever. Some substances are slow to degrade, but they still degrade over time. Those that are non-biodegradable should not degrade, even over long periods of time.

it varies greatly from a few hours to several years. depends on the substance, the envirument its in and the surrounding flora and founa
He/she requires heat, water, food, oxygen, a way of disposing of waste, and pressure. If all of those are present, indefinitely.
Depends on what is it used for and water quality and if it was installed properly .Is it waste, soil, vent , condensate? or used as a hand rail or monkey bars?
nuclear waste is a never ending source of hurt for the environment. truly we should try to contain it for 500 to a thousand years as the waste it produces is deadly and can cause tumors or cancer.
Radioactive waste depending on the dosage should be classified as 'pollution'. The waste word used really difines my reasoning. Its waste, unneeded products in our atmosphere, even if it is safe raioactive waste (in which i dont believe there is such a thing because further testing has not been done to work out future effects of radioactive waste on humans we may be slowly mutating) it is still unnatural 'waste' in our atmosphere. Definition of Pollution: the introduction of harmful substances or products into the environment. Radiation is not classified as healthy neither is waste and so far as i said there hasn't been further investigating into the long term effects of radiation even small leaks, so i would say that Raioactive waste/leaks should be classed as pollution.
The largest parasite that lives in a human is the tapeworm, which can grow up to 10 m long. Tapeworms are internal parasites that thrives in the intestine, resulting in blocked intestines and waste substances being released into the person's bloodstream.
Its is removed by the muscles along the behind push it. I is anywhere from 5mm long -1cm long. It takes about 10 mins for a barancle to produce waste and it produces waste 2-4 times a week!
The A has a long A sound as in tape or waste. The E is silent.
