Impact on animals

Waste that we dump into the water, weather it's down the toilet, drain or straight into the river, can cause serious harm to our sea creatures. Some choke on it, while others eat it, mistaking it for food.
The toxins, bacteria and heavy metals dumped into the water can cause death for many sea creatures, because they breath in the contaminated water. It's like us constantly breathing in gasoline. It would eventually kill us.
Besides killing aquatic animals, water pollution can also cause damage to animals on land. If, say, a deers habitat was close to a contaminated river or stream, the animal would constantly be drinking the water. The bacteria from the water would then grow in the deer.
Some insects, like dragonflies, spend their larva stage underwater, but live on land during adulthood. These insects are a great source of food for other predators, so if the water the insects hatch in is polluted, then they will diminish in numbers and therefor, terrestrial animals who feed on them will not have any food.
Everyday activities, such as using shampoo or soap with toxins in it, or using fertilizers on your lawn can lead to water pollution.
When it rains, the lawn fertilizer drains down into the drains in the road and leads directly to a lake or river. The water is not treated.
That river or lake is probably where you get your drinking water from, so you are essentially drinking your own back wash.
Water pollution is also caused by toxic chemicals ,like heavy metals, that are dumped into the ocean. They contaminate fish and sea creatures.
Additionally, those contaminated fish are fished out of the water and eaten by humans. Once again, back wash! WE contaminate our own drinking water and food!
Garbage that we dump into the water, can cause serious harm to sea creatures. Some choke on it, while others eat it.

Also, in poor countries, they cannot afford a water treatment plant, so they drink unsanitary water from swamps and ponds. Sadly, the water could be full of nasty bacteria, such as animal excrement, which is more than common to end up in their drinking water.
Water pollution has increased dangerously since the 1990s, and if we don't do something soon, our water will be so filthy, we might all end up with colora or some other type of disease caused by contaminated water.

Our first activity will clarify the severe damage that polluted water causes for our drinking water.
