When careless human activities decrease the amount of plant life, the amount of runoff usually increases. Without sufficient vegetation to absorb water, runoff carries more pollutants and sediment into water bodies, leading to water pollution and sedimentation, which can harm aquatic ecosystems.
Not put pollutants in in the first place.... On a more serious note: bacteria that will feed off the pollutants is usually your best bet. It is infinitely harder to remove pollutants than it is to put them in.
The amount of water in the ocean temporary decrease.
Biochemical oxygen demand (BOD) is caused by the presence of organic pollutants in water, such as sewage, agricultural runoff, and industrial effluents. These organic pollutants provide a food source for bacteria, which consume oxygen as they break down the pollutants, leading to a decrease in oxygen levels in the water.
It's NOT "A" B: A decrease in the amount of organic matter.
water pollution occurs where a body of water is adversely affected due to the addition of amount of waste water.
The Clean Water Act regulates pollutants such as oil and grease, toxic metals, pesticides, and industrial chemicals. These pollutants can come from various sources such as industrial discharges, agriculture runoff, and municipal sewage. The Act sets limits on the amount of these pollutants that can be discharged into water bodies to protect water quality and aquatic life.
Clean water also decreases and pollution rises.But it can also be dangerous
