No. That would be unhealthy and disgusting. You will most likely get sick, or get stuck on something and drown.
scientists realized that beaches were being polluted when they studied them ............isn't that obvious .
Yes, polluted can be used as an adjective. Example: Don't swim in the polluted lake.
Yes, it is.
you swim..............................................
Some are, some are heavily polluted...try going to less touristy areas for better beaches.
No beach of Davao City has been listed as polluted. Retrospectively, it only shows how responsible the people of Davao are.
Yes!!!!! Tons, most are beautiful and untouched, but some are horrendously polluted.
It isn't and I know because I live there and swim in it.
Yes. The EPA and local officials have been monitoring water quality. If there is any danger, they have the authority to close beaches to swimming.
Yes. It does, of course, depend on exactly what the pollution is and whether you swallow any of it or not. Technically, any lake a motorboat has been on is "polluted", since it will contain traces of oil, but you can probably swim in that with no problems.
Some are, some aren't. It depends on the beach and the efforts to keep / maintian it to be clean.
I think so. I don't know how to explain a whole lot so read this article and it may help you. http://www.athensguide.com/beaches/index.htm
