There are actually multiple causes of water pollution, (yes there are more than one) that affect surface water, such as sewage and waste water, marine dumping, industrial waste, oil pollution, and global warming. I know that there is more than that but those are the five that I will mention in my PSA because I don't have enough patients to write about them all.
The type of water pollution that would affect the type of water I’m writing about would be surface pollution because I’m talking about river/creeks and oceans which are on the surface of the earth.
One point source of water pollution would have to be sewage plants (they treat raw sewage) when they spill. Like how not too terribly long ago a sewage plant accidentally overflowed polluting a TON of the peninsula and made it so people couldn’t swim or wade in beaches or else the could get sick or under extreme circumstances possibly die, I mean SERIOUSLY PEOPLE! I get it that we had a flood but when you're handling dangerous stuff like that you should be prepared for anything!
From what I have learned one non-point source of pollution would be rain runoff from homes and other places because of the oil from cars with leaks or from accidentally (or on purpose) spilling oil when refilling their oil gauge, which is then transported by the rain water to the ocean or river or anything really!
Our actions actually make a difference in case you didn't know. Like how us spilling oil into the ocean is polluting everything and killing all sorts of animals, sea life, and even coral reefs because the animals drink and even LIVE in the polluted water. The oil also degrades coral reefs, destroying animals homes and not letting them have hiding spots from predators that will then find, kill, and possibly make certain species go extinct causing EVEN MORE problems for us and the environment. To also add to the list of problems most industrial water filters use either oil or natural gas (natural gas is better but still not good) to power themselves warming up the planet essentially destroying the earth on spill at a time.
So, now you may be wondering, “Well what can I do? This is just way too much to handle!” Well it may be too much for one person to handle but just by doing a couple things you can help save the earth (and telling your friends is amazing.) So if you want to help the earth just do these simple things:
1) don't use your car for every last thing. I mean, you have legs for a reason, ok? Because using your car releases co2 into the air and that's what's warming our planet.
2) recycle. If you don't have a recycling bin use an empty box, my mom and I do! Recycling will help reduce water pollution and not make the great Pacific garbage patch bigger.
3) don't use planes as much. If you can, use your car because planes release a TON of co2 which is way worse than using a car.
Also the reason why releasing co2 is bad is because our ocean is absorbing all the heat, causing ocean acidification causing algae blooms that release a harmful, sometimes fatal toxin, and creating dead zones in the ocean so fish can’t go there.
And those are really the big things that you can do to help our planet.
