Dirty water.

One way that water gets contaminated is that, in some places hen people poop just goes down a tub and into our local river or ocean and many other water places so your going to be drinking other people's poop and pee when ou drink water or use water in one of your foods.

One of the dangers of water contamination is that it can give you really bad diarrhea. And if you do diarrhea everyday it is really bad for you because you're loosing lost of water from your body and you can die. Another dangerous thing is that if you have a baby and you give it the dirt fosett water it can grow up to having problems and being really sick.

Well in my house we have a filter when you put the water in it first cleans our water i don't think that it cleans every single bad thing in there but it cleans most of the things so you wont get sick.Another invention is a little tub mostly for people with contaminated water that you can stick in the water and suck it in like a straw but whats different about this is that it cleans our water before it goes in your mouth.

I think they don't have these inventions maybe becouse they cant afford it or never heard of them before. Or maybe they just don't know that there water has all these nasty things in them.The problably think that there water is very clean and doesn't have a speck of dust in it. Well who knows maybe the have a completely different reason.
