Because people are dumping garbage into water
It Effects The earth?

Citarum is the most polluted river on Earth.
About 2% of the total water on Earth is polluted to the point that humans cannot drink it.97% is ocean water, and a lot of water is locked in the ice caps or aquaphors far underground, so this is a significant amount. Only about 1% is drinkable for humans.
well if the shrimp are cuaght in polluted water then they are polluted but if there are caught in fresh water then theyt are not polluted
polluted water is more dangerous for use and contaminated water is poisiones then polluted
One will know if the water is polluted by putting a water reader in the body of liquid. This water reader will determine if the water is polluted or not.
well its not very polluted but it does have global warming
Polluted The Polluted creek is full of garbage.
It depends what it is polluted with.
Probably every single bit of the surface water, to one extent or another. Answer: The answer is dependent on your conditions for "polluted" If potability (drinkability) is the criteria, then all of the Earths seas and oceans are polluted due to the salt content. If the presence of any levels of salt or organic material is a concern (i.e. is the water chemically pure water) all water is polluted. About 70% of our Earth's surface is covered by water. However:97.5% of all water is salt water, only 2.5% is fresh waterAbout 70% of fresh water is frozen in Antarctica and Greenland;Of the remainder most is underground or soil moisture,This leaves about less than 1% of the world's fresh water (~0.007% of all water on earth) for direct human uses. COMMENT: But that's not the question, the question is 'what percentage of freshwater is polluted? Is it 25%, is it more? Less? Would you prefer to use a pie graphic...showing a third or more? We didn't ask for the answers we were given and we'd really appreciate it if you simply answer the question instead of answering every else EXCEPT the question. - Jane Streeter.
A polluted water may be a homogeneous or a heterogeneous mixture.
