Answer 2

How Do Humans Pollute Water

Answer 3

You set up a false dichotomy. Accepting all the facts about land, sea, humans - the fact is that pollution travels in the air. We are polluting 100% of the atmosphere, and it is changes in the atmosphere that cause global warming. It is also true from the paleontology record that there have been natural shifts in global temperature over time - and it's also true that the rate of change in the last 50 years far exceeds anything we can see in ice core and rock samples from the last few million years. Yes, there may well be a natural warming happening anyway, but it is absolutely true that we have accelerated that process with pollution by adding millions of tons of unnatural carbon dioxide and other green house gases to our air. Other changes, such as the release of CFCs over a 30 year period, have substantially damaged the structure of the atmosphere, affecting not only global warming but our overall exposure to radiation from the sun. The fact is that there is an uneven distribution of ozone anyway, and it is thinnest at the polls. CFCs moving through the atmosphere end up at the polls, further reducing the ozone layer. This may well have genetic consequences in some parts of the globe.

Answer 5

Wow, 20 is a lot! Here goes, but you have to do the rest, this is to make you think about your environment.

Agriculture; animals and pesticides. Now, how do you think they pollute the water?

Run off from roadways. Now, how to you think that pollutes the water? I will give you a hint. Cars and trucks lose something that makes them run, in the engine, that ends up on the roadways.

Now you think of the rest. Good luck!

Answer 6

Dumping hazardous material into it.
Emissions from vehicles.
Dumping used oil into the ground.
Oil spills from tankers.
Sewer system overflows
Septic tank overflows
Camping (usually by a lake or river)
Emissions from boats
We created acid rain from pollution
shipwrecks
bombs
landfills

sorry, that's all i have. good luck!

Answer 7

By causing oil spills in San Francisco and South Korea.

Answer 8

we need water to live love and play so whatever we do in on or around water pollutes it

Answer 9

garbage
oil spills
too much plankton (that green stuff)
sewage
toxic chemicals
cars (cabon monoxide)
acid rain
factories
It's not 20 but i hope 8 is a good start

Answer 10

Flushing old drugs down the toilet.

Air poloution will contaminate the water when it rains.

hosing off your driveway into the storm drains.

underground fuel tanks that rust and leak into the underground aquifers.

cow and pig farms that let the waste seep into the soil and eventually into the aquafirs.

boat motor exhausts and drips into lakes and rivers.

pesticides that seep into the soils and into irrigation systems.

well, there are a few more for you.
