Obviously, the poison that is used in fishing (mainly cyanide) is harmful for the ocean because it may poison other fish over the years. Also, the usage of explosives are harmful because they all kill off things such as coral, and the damaging of coral reefs can take decades before it reverts back to its normal state. To reduce or totally eliminate the way these local practices are impacting the environment, we can place restrictions on what can be used in fishing, and how much you can catch. For example, we can limit fishers to only 10 fish a day. This would give the fish plenty of time to reproduce and would keep the population of the fish steady.
However, it 's not only just because of man-made reasons. The coastal marshes disappearing can also be affected by natural causes. Sediment is being deposited into a river delta increasing the weight, which causes the entire area to sink (p. 11). Depositing may sound like a positive cause, but however if the course of the sediment changes then no new sediment will continue to be deposited. Another natural cause is oceans and hurricanes.
The article states that there is a rapid decline in the population of sea otters, the mammals found along the coast of California to Alaska. The article claims that the reason for the declination is because of environmental pollution and provides two reasons of support. However, the speaker refutes that the dwindling is due to predation. First, the reading claims that environmental pollution is the most likely cause because oil rigs found along the coast cause pollution to a greater extent. Further, the increased in chemical levels decreases the immune strength of the sea otters which indirectly leads to death.
The question is not if there will be an oil spill, the question is when. There have been several oil spills on the west coast, as it’s an oil rich coast. Oil spills can be catastrophic to marine ecosystems. It affects marine birds because it soaks into their feathers changing their ability to float, which can lead to death. It also is toxic to many aquatic species during various parts of their life cycles.
Pollution is also a significant environmental issue HAL is facing. More oil reaches the ocean each year, a massive amount of oil has been accidently spilled from ships, which in turn is destroying animal and aquatic plant life. Tourism is also having a major impact on the environment. Waste and sewage from resorts, hotels, and restaurants, especially in heavily visited coastal areas, could find their
The wells the colonists made were risky because of the high chance of salt water intrusion. Also, you have to remember the human waste festering in the water, and even when the tides rush in it doesn’t move the waste out. Therefore, there could be diseases in the water, which could kill the colonists. Remember that the people in the 1600s could not filter water like we can so the colonists (because of the lack of freshwater) had to drink the contaminated water, which could lead to death. This is why I believe that one of the major factors of the colonists deaths is the environment.
A decrease in tourism lowers revenue in a certain the area, and threatens economies that are increasingly dependent on their local tourism. Commercial fisheries are threatened because acidification harms calcifying organisms which form the base of the Arctic food webs. pteropods and brittle stars both from the base of the Arctic food webs and are both seriously damaged from acidification. Pteropods shells dissolve with increasing acidification and the brittle stars lose muscle mass when re-growing appendages. This problem is so detrimental because if not solved, can eliminate species of marine life from different parts of the globe, and can possibly create an ocean in which is not safe for any living being.
However, the migrant of wildlife will become permanent environmental damages because our soil will lose its moisture and quality that includes the loss of wetlands that can lead to a permanent loss of biological productivity. Drought in California can be a contributing factor to wildfire because dry, hot, and changes in temperatures
Spilled oil can harm marine animals because its chemical components are poisonous. This can take a negative toll on animals from internal exposure to oil through swallowing the oil or inhalation and from external exposure through the animals skin and eye irritation. The spilling of oil penetrates into the feathers and fur of birds, breaks down their plume capabilities which makes them heavier, disabling them from flying and killing them through poisoning and/or hypothermia. Birds that groom themselves to get rid of the oil accidentally swallow the poisonous chemical and die due to the toxic effects. During most oil spills, seabirds are harmed and killed in greater numbers than other kinds of creatures.
In a website Causes and effects of environmental pollution- conserves energy future.(2009). There is an article the writer says that ''acid rains can change the composition of the rivers and the sea, making them toxic for fishes, because the quality of ozone in the thower plants of the atmosphere can causes lung to all animals". that’s shows that what people do it comes back to them in bad effects that they may kill all the animals that they need them for therapy and they may cause a diseases that ends human life . Also as we know that also the plants damaged from the pollution that they may be extinct and people cannot have a good healthy and fresh air that they maybe be sick from it and also the soil will be not good to plant in it and
