What harm does marine pollution and litter bring to sharks? 15

The harm of plastic waste to marine life can be said to be huge, even if the plastic is buried in the soil for decades can not be degraded, everyone who has studied chemistry knows that the carbon in the molecular structure of the plastic is combined with a single bond, which means that the addition reaction that is most likely to occur in organic chemistry cannot occur, which is why plastic is resistant to acid, alkali and corrosion, and plastic is easy to be eaten by marine organisms into the stomach, and many sharks have been stuffed with garbage plastic bags in the past. Many poultry will eat foam particles into the stomach, the most direct impact is that they can not be excreted in the stomach, the stomach is always full, and after a long time, the animal will be malnourished, resulting in a series of symptoms such as decreased immunity to death.

Let's look at the specifics: eutrophication, which harms the quality of seawater, leads to a decrease in the oxygen content of the water, and can also produce a lot of toxic substances, which kills plankton in the water and leads to the death of fish.

Heavy metal pollution, through bioaccumulation, is a serious damage to organisms at the top of the food chain.

Oil pollution, covering the sea level, so that sunlight, air can not enter the seawater, fish and mammals in the water and birds are harmed, sticky and difficult to remove, damage the local ecological environment

Marine polluted garbage will face death if sharks eat it by mistake, such as a large amount of polluted garbage will bring disaster to sharks, resulting in the extinction of sharks!

Sharks can be killed or injured by plastic debris.

Sharks are entangled in fishing nets.

Some sharks swallow plastic or other garbage by mistake, which can cause intestinal obstruction.

It has damaged the marine environment and has had a serious impact on the survival of sharks.

Marine pollution will cause immeasurable harm to marine organisms, affecting the basic life activities and reproduction of marine organisms.

According to Fun Science on July 8, scientists said in a report published on July 4 that they had documented more than 1,000 incidents of sharks and rays becoming entangled in plastic. The actual number is likely to be much higher – the study only recorded examples that were mentioned in scientific journal articles and on Twitter. The IUCN says sharks and rays are at higher risk of extinction than most other animals.

1. Sharks will mistakenly swallow plastic waste as food, and large pieces of plastic waste will get stuck in the animal's esophagus and stomach, or cut organs to cause infection and death, or make sharks unable to forage until starvation.

2. Marine debris will also entangle the shark's body, making it impossible to break free, and even fatal in severe cases.

3. Marine litter inhibits the photosynthesis of marine plants, reduces their oxygen production, and leads to a decrease in the available oxygen of marine organisms, which greatly inhibits the activities and vitality of marine organisms. The ensuing impact is on the entire marine ecosystem, disrupting the homeostasis of the marine ecosystem.

Death: Marine debris can accidentally ingest or become entangled in marine organisms, causing them to suffocate, starve, poison, or otherwise injure them, ultimately leading to death.

Damage to marine ecosystems: Marine ecosystems are complex ecosystems, and marine litter affects the marine food chain and affects the balance of marine ecosystems.

Polluting the marine environment: Marine litter can release harmful chemicals that pollute the marine environment. These chemicals not only affect marine life, but also human health.

Destruction of marine landscapes: Marine litter can affect the beauty of the ocean and affect the tourism industry.

Economic losses: Marine litter pollution can have a negative impact on fisheries, shipping and tourism, among others, resulting in economic losses.

In summary, marine litter pollution has a serious impact on human beings and marine ecosystems, and measures should be taken to prevent and control it.

Marine litter not only causes visual pollution, but also water bodies that can deteriorate water quality.

The largest amount of plastic waste in the ocean is discarded fishing nets, which are missing or sometimes miles long, and are known to fishermen as "ghost nets".

By the currents, these nets are twisted together to become "death traps" for marine mammals, which entangle and drown thousands of seals, sea lions and dolphins every year.

Other marine creatures tend to swallow some plastic products as food, such as sea turtles, which are particularly fond of eating plastic bags that resemble jellyfish.

Seabirds prefer lighters and toothbrushes because they resemble small fish, but when they try to spit out something and feed it back to their young, the weaker young often choke to death. Plastic products cannot be digested and decomposed in the animal's body, and can cause stomach discomfort, abnormal movement, decreased fertility and even death after ingestion. The death of marine life eventually leads to the disruption of marine ecosystems.

Marine litter pollution can have several consequences:

1.Biological death: Marine garbage can be accidentally ingested or accidentally entered into the body of organisms, resulting in the death or abnormal growth of organisms, affecting the ecological balance of the ocean.

2.Damage to water quality: Harmful substances in marine garbage will pollute seawater, causing damage to the quality of water reform, and affecting the living environment of marine life.

3.Bad smell: Marine debris accumulates on the beach or on the surface of the sea, which can emit an unpleasant odor and affect the quality of life of the surrounding residents.

4.Harm to human health: Harmful substances in marine litter can cause harm to human health, such as polluting seafood.

Marine litter not only causes visual pollution, but also causes water pollution and deterioration of water quality.

Pollution of the oceans occurs mainly in bays close to the mainland.

Due to the dense population and industry, a large amount of wastewater and solid waste is dumped into seawater, and the water flow exchange is not smooth due to the twists and turns of the coast, which changes the temperature, pH, salinity, transparency, species and quantity of organisms and other characteristics of seawater, which poses a hazard to the ecological balance of the ocean. acres of infiltration.

Marine pollution is prominently manifested in several aspects, such as oil pollution, red tides, accumulation of toxic substances, plastic pollution and nuclear pollution.

Oil and "COD" have exceeded the standard in various seas.

In the Bohai Sea, which is the most polluted, pollution has caused the relocation of fishing grounds, the death of fish stocks, the flooding of red tides, the abandonment of some tidal flat farms, and the loss of some precious marine resources.

Marine litter pollution will have serious consequences for the marine ecological environment and human beings. The destruction of the marine ecological environment will adversely affect the survival and reproduction of marine organisms, and even lead to the collapse of the ecosystem. Humans may cause health problems such as cancer and neurotoxicity by eating contaminated marine organisms or coming into direct contact with pollutants.

In addition, marine litter can also affect the development of related industries such as fishing and tourism, which can have a negative impact on the local economy.

Marine litter pollution will lead to a large number of diseases of marine organisms, and in serious cases, it will also lead to the death of marine organisms in large areas. Ultimately, it will affect the ecological balance and the safety of our human beings.

Marine litter pollutes the ecological environment of the broken oceans, affects the food chain of the oceans, and deprives the creatures in the oceans of their homes.

We usually say that we must take care of the environment, if we say that marine garbage pollution, it will bring a lot of disadvantages to our lives, such as the impact on marine organisms will destroy their living environment and affect the ecological balance, which will also lead to adverse consequences.

Hello! Dear, very high difference Yu Kuanxing for you to answer! Marine environmental pollution will bring many dangers to whale sharks.

The main hazards are as follows:1Whale sharks inhale pollutants:

Whale sharks breathe in airborne pollutants such as oil, heavy metals, volatile organic compounds, etc., which pose a serious threat to their health. 2.Whale sharks eat pollutants:

Whale sharks eat contaminated fish and shrimp in seawater, which absorbs pollutants and causes problems in their bodies. 3.Whale sharks poisoned by contaminants:

High concentrations of pollutants can slowly dismantle and change the detoxification ability of whale sharks, causing whale sharks to accumulate pollutants and then be poisoned by pollutants. 4.Impaired reproductive capacity of whale sharks:

Contaminants can alter the hormonal balance in whale sharks, which can affect the ability of whale sharks to reproduce. 5.Other questions:

In addition, when the level of pollutants is too high, it may also have an impact on the immune system, nervous system, etc. of whale sharks, which can cause other problems.
