Internationally, marine debris poses a great danger to marine life because marine debris follows the flow of ocean currents and travels worldwide. Studies show that many marine species are wounded and killed when they ingest or become entangled in marine trash. For example, more than 250 marine species were reported to be entangled in or have ingested marine debris (Marine Mammal Commission, 1998). By restraining movements, entanglement could kill marine animals through starvation. Moreover, ingestion of marine trash such as plastic might kill the animals through suffocation and starvation.
Throwing paper made items on the ground they will travel into the water. Animals would eat these things or would get caught in these items and could die if they weren’t rescued. 5. Don’t use items that harm marine life. Certain products contribute to the harming of marine ecosystems.
“Any change or modification in the physical, chemical and biological properties of water that will have a detrimental consequence on living things is water pollution.” Water pollution affects the drinking water, lakes, rivers and all over the world. In many developing countries, the polluted water leads to death. Figure 4: Ways of polluting water Types of Water Pollution Water pollution has many types some are discussed in this section: 1. Nutrient
Because of that are floods increasingly common. We also pollute land. It is caused by throwing garbage on the land and river banks, leakage from chemical tanks, oil spills and other chemicals, which came into the soil by accidental contamination. Animals can eat garbage on land and river banks and they can die because of asphyxiation. Absolutely farming is the most dangerous caused for land pollution.
EFFECT The effects on the city and water supply have been enormous.To start with, the means of water supply have been transformed into open sewers. The consequence of people using water canals to clean their clothes is that the detergent used has spread. The detergent cannot dissolve due to the concentration of chemicals in the already contaminated water, and spreads throughout the canal and kills fishes and other living organisms. As for the waste produced by industries and factories, lots of this waste contains heavy metals: when it is dumped into the open canals, these toxic, poisonous metals are dumped along with it. One of the most toxic metals is mercury, which can have very serious side effects if ingested in excess, including paralysis, liver and kidney failure, and death.
Coral reefs are dying at an alarming rate thanks to many factors, mostly caused by humans. For instance, when we pollute the earth and our oceans by burning greenhouse gases, we cause climate change. This affects the coral as they can’t withstand the water raising by only a few degrees. This often causes coral bleaching, which kills these animals. Also, storms can destroy reefs, also often caused by humans affecting the environment.
When these organisms become poisoned due to plastic consumption, this causes problems for the larger animals that depend on them for food. This can lead problems, in each step further along the food chain. Plus, there is plastic present in the fish that many people eat every day. • Leads to Land Pollution When plastic is dumped in landfills, it comes in contact with water and form hazardous chemicals. When these chemicals goes underground, they pollute the water quality.
The pollutants that discharge directly or indirectly into water bodies without sufficient treatment to remove harmful mixtures are called water pollution ("Environmental pollution," n.d.). The lives of animals are disturbed by human activities that contaminate the soil. Environmental contamination kills the fish and insects, which leads them to extinction. To explain, Pesticides are a source of pollution, agriculturalists use pesticides to prevent insects from eating crops. Pesticides stay in harvests, wild plants eaten by herbivores, and insects.
The cause of this was a nasty toxin called microcystin. Microcystin appears because of human pollution and fertilizers that flow into rivers and lakes which then lead to the ocean. Cancer-causing chemicals called PCBs and pesticides like DDT are in marine mammals ' fatty tissues and they cause serious harm. 2. Many health departments encourage people not to swim 72 hours after it rains because the coastal waters are
Introduction Terrestrial pollution is the containing of the land through dumping of waste and garbage and the presentation of toxins into the into the environment, in other words terrestrial pollution is the destruction of the earth’s surface area ground either directly or indirectly by human activities , also the harmful concentration of substances that are beyond the environment’s capacity to handle. Land pollution is the largest problem faced in Tembisa and it has become bad enough, it damages the soil and this is caused by the overpopulation of people in this township as a result of informal settlement that is also a problem for the Ekurhuleni Metropolitan Municipality and the government of the Gauteng province. As they unable to serve everyone’s need in this township. Over 8000 people are living in
