In my opinion water pollution is the most important problem that the Earth is facing today. I believe that, because without water there wouldn't be life in this planet. All living organisms need water to survive. Water pollution is the contamination of water bodies. Water pollution affects plants and organisms living in these bodies of water; and, in almost all cases the effect is damaging either to individual species and populations, but also to the natural biological communities.
So, as I said water is what keep us alive. If we keep polluting water life on Earth will disappear. Water pollution affects everyone, people, animals, plants.... everything. Boston Harbor is an excellent example of how badly pollution can damage bodies of water. The water is filled with toxic waste and sewage, and routinely receives more waste when rainfall pushes it into the harbor.
There are many causes of water pollution. The specific contaminants leading to pollution in water include a wide spectrum of chemicals, pathogens, and physical or sensory changes such as elevated temperature and discoloration. While many of the chemicals and substances that are regulated may be naturally occurring the concentration is often the key in determining what is a natural component of water, and what is a contaminant.
We can still save the planet, we only have to: Replace shower heads and faucet aerators with water efficient models. Use a water-filled milk jug or plastic bottle in your toilet tank to displace water; this allows your toilet
to operate using less water. Choose non phosphate or low phosphate detergents. High phosphate levels in lakes and streams
can kill fish and other wildlife. Use a broom instead of water to clean your driveway or garage . Do not sweep debris into the
street or storm sewer. Put a spray nozzle on the end of your hose for car washing and plant watering to prevent the hose
from continually releasing water and to control the amount of water used.
So here's my opinion about water pollution. We should take care of it now, when we still have some time before everything in Earth collapses at cause of water pollution. I'm posting too some excellent ways to prevent water pollution so everyone can see them and use them to help the world.
