Heck, Praveena, you sure did get a good reply from Ted ... and probably deserved his answer, too.
It's thanks to Plastics that many industrial areas are not polluting so much as they have replaced many metals ... the advantages far, far exceed any disadvantages. They have, to answer your question, benefited mankind.
The chemicals used? Mainly oil derived, (eg PVC's), some from natural gases (Pe and PP), others from compounding or synthesizing various gases/solvents but virtually ALL relate to carbon and, like a parrot, all are Poly this or Poly that meaning that they have been polymerized by chemists for a certain function and end use.

I really think that you should look around you at the lakes and rivers Praveena. You could see garbage in them. The causes of plastic pollution is that careless self absorbed people don't care about any pollution as long as it doesn't effect them. But wait and see what happens when it gets to be too much!

There is certainly truth to that Cecilia, thanks. But it's also a simplification of a complex problem and implies that the solution to the problem only requires police officers to write citations. What it actually requires is for people to think deeply.

I am pleased to find a site concerned with plastic. Or at least lapping at the edge of the pool. Plastic pollution (just in its manufacture) is far greater than other very wasteful processes, aluminium included. Plastic has changed man-kind but we need to address how it will continue to do so.

++++++ Respected sir, K.Vijayalakshmi
+++++++ YOUR INFORMATION IS VERY NICE. I WANT TO MAKE A PROJECT
ON PLASTIC POLLUTION.SO PLEASE GIVE ME YOUR INFORMATION
ABOUT IT. R SHAH
+++++++ Shah, we explained the problem with Praveena's posting, but Vijay and yourself are ignoring what was said. If you have a specific stumbling point, we will be pleased to help; but to expect someone to simply do your homework for you is another matter.
Hello my name is Caleb. I am writing an essay on the
effects of waste plastic on the environment and I have
searched through many news papers, books, and hundreds of
web pages trying to find out if plastic, when it decomposes,
leaves chemicals that effect the ground or water were it
decomposes. The closest answer I have found to my question
was from a high school teacher, he said that there was a
possibility that when plastic breaks down it might leave
chemicals that could pollute the ground or water around it.
If you have any knowledge on this matter it would be greatly
appreciated. Caleb v
+++++++ I think part of your problem is that there are thousands of different plastics, Caleb. What may be true of one isn't true of the other. But if you google "when plastic decomposes", you will see some great topics. As long as the plastic has deteriorated into small enough pieces that it is not in troublesome shapes that living things choke on or swallow, and it is non-toxic, it may not be a really major immediate concern. But the basic issue is that many plastics are long chain molecules which no living organisms can "digest", that is, they are not biodegradable. Thus, they may persist for a very long time. It can't be a good idea for this stuff to just accumulate. We now have several biodegradable plastics based on plant fibers instead of oil, and current thinking is that it would be best to use them when their properties suit the application.

Does plastic pollution have a good side?
Martha R
student - Palmdale, California
There are usually two sides to everything, Martha, but there is also such a thing as an "oxymoron". Look up the word "pollution". Depending on the definition you find, you may discover that "pollution" may be defined as a waste product in a location where it is harmful.
I think the "advantages" are few and small. But here is one for an example: plastic lumber probably would not exist if we didn't have plastic waste to start from.

January 12, 2009 Shaneed, Nilesh: we were through this twice already on this one page. If you get stuck on something, we'll help. But you don't just pass your homework assignment on to us to do for you :-) Go to google news and search for "plastic pollution". Pick one or two of the news articles that capture your interest and work your way through them for further sources leading to greater details and deeper insights. It is so very easy today. Regards,
August 31, 2009 If completely neglected.... what can the worst possible effects of plastic pollution be?? Prerana Nair
August , 2009 Hi, Prerana. This is subjective because some people even think the earth would be better off without mankind. So tell me what you think the worst possible catastrophe that could happen would be, and I will try to explain how plastic pollution could be involved in that. Regards,
