There are a lot of different controversial ways we could start saving the planet and cutting back on water pollution is defiantly one of the more important/ practical ones that anybody could start doing. Yes, we should defiantly start to cut back on water pollution or start trying to prevent it because it could cause future problems in the ocean environment and for the next generation of people to live on this earth. Water pollution could change the environment in the water chemically and biologically , it’s a huge health issue to people who are in taking the water for drinking, and elimination factories or underground oil mines could help prevent a large amount of water pollution. Water pollution has a huge effect on the biological and chemical make up of the ocean. This makes water not useable for people to consume, this is known as pollution. Nutrients that affect growth of bacteria and oxygen-consuming decomposers in a river or lake are helping the bacteria but can be deadly to game …show more content…
fish populations. Killing off the fish would effect the human population because then there would be a shortage of fish putting fishermen out of work and causing a shortage of fish. The most important water pollutants are sediments, toxins, wastes that demand oxygen, and plant nutrients. Trash makes up most seen type of water pollution in most rivers, lakes and oceans. Construction sites add 75 billion tons of sediment each year to rivers and lakes and oceans. Fish Lay their eggs in smooth gravel beds of rock. All this pollution fills and blocks lakes and reservoirs, shipping channels, hydroelectric turbines also making the cost of purifying the water go up. Water pollution could have a huge impact on the health/ purification of the water which could cause disease or major health issues. The U.S. Environmental Protection Agency looks over the main standards of the water health which are legally enforced standards which regard water contained in public water systems. Primary standards are set to promote public health by setting limits to help save the people by making sure the peoples water is safe to drink. Poisonous chemicals can interfere with the basic enzyme that make life possible making the organism more likely to die. Some important toxins found in water are metals, elements, acids, salts, and chemicals such as pesticides, solvents, and industrial wastes. Some of these things are so toxic that exposure to low levels of the substance can be dangerous. Some fish can take these chemicals, hold on to them, and store them making them dangerously more toxic which then can be distributed through food chains or stores. Fish all over the United States have accumulated mercury which is released by mostly power plants to levels that are a threat to human health for some people with certain health problems. Another way we could help water pollution is to eliminate some factories that are emptying their waste into the water or eliminate the use of wells/ rigs in the middle of the water ways.
There are natural sources of water contamination, oil leaks, and sedimentation from desert erosion, but scientists mostly focus on water pollution caused by human actions and that are not relateable to weather conditions. Water pollution control regulations usually are categorized between point and nonpoint pollution sources. Factories, power plants, sewage treatment facilities, and oil wells, are known as point sources because they release pollution from specific locations. The United State works toward a goal of making all waters usable for fishing and swimming. Investments in sewage treatment, regulation of waste disposal and factory efficiency have resulted in significant water quality increases in many areas around the world
today. Anybody can go to the beach or into the woods near a river and pick up a few cans or bottles to help the environment so why cant you? Help save the world for future generations. The water can change by what toxins we put in it so why not just let the environment be and let it grow to the best it can be. Elimination of factories would benefit the water ways because less waste would be put into the large water ways. And also the elimination of waste would help prevent a lot of health issues saving millions of lives. We can change the world its just the matter of taking our words and making them actions.
