However, mercury evidently was lost during the mining process, and ended up either flowing to the downstream environments, leaking into underground soil or bedrock. Small mercury particles were often floating on the top of the water for miles past the mining sight. Mercury was the quick fix that settlers were looking for. However, this quick fix caused a life-time of destruction, mercury found its way not only contaminating the water supply and soil but through the food chain. More often found on the wildlife and vegetation, especially in the tissues of fish in the rivers, thus causing serious health issues to humans eating high amounts of fish.
The oil spill took a huge tool on alaskas fishing industry, forcing many Alaskan citizens which depended on the fish for their income to be pressured into some kind of a depression. In particular, the oil spill had affected trade of Alaska, particularly the industry of fishing in the region. According to surverys taken fishermen of Alaska have lost over three quarters of a billion. This is due to the oil spill because it ruined the Alaskan salmon in the region. The total damage done to the ecosystem and fish lost weighed in around six hundred million dollars (Fernando,
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.
The Asian carp should be removed from the Great Lakes as shown in the following paragraphs. The Asian carp are an invasive species because they are killing off many native species by either destroying their habitats or eating a large amount of food. Their population spreads very quickly, which makes it hard to stop or control them. Carp that are filter-feeder often compete with fish such as bigmouth buffalo and paddlefish, by taking away some of their food sources. They can also affect human lives; they have been known to jump up to 10 feet out of the water and even break bones.
People complain about pollution from factories, cars, global warming, and the melting of polar ice caps, yet many people disregard the dangerous that come with fracking. Fracking is the process of injecting liquid at high pressure into subterranean rocks, and/or boreholes to force open existing fissures and extract oil or gas. Fracking is causing an epidemic economically and environmentally. Fracking is continuously destroying the earth day by day. From the endless fracking today’s economy is depleting.
In my area there has an escalated amount of pollution. The amount of pollution has affected the protected wildlife areas and parks. Polluted rivers are killing the wildlife, and animals are in danger because of the heavy amounts of pollution. A lot of people aren 't properly recycling their waste and that affects the environment, and the wildlife living in it, greatly. The Chesapeake Bay Foundation has been trying to raise awareness around pollution since 1967.
These plants sometimes look red due to their photosynthetic pigments. Now they may not seem harmful, but they are a huge threat to fish and humans. The reason they are a threat to fish is because the algae irritates the fish’s gills, eventually suffocating them. The reason they are harmful to humans is because they cause millions of dollars of damage because of they have to clean up a massive amount of dead fish, beaches have to be closed to the problem is resolved, fisheries and shell fisheries are closed to harvesting. Unfortunately, people also have to go to the hospital to get the bio toxins removed because they ate this specific
The human effects on Salmon Salmon are a crucial part of are the environment. They create nutrients in the water and the forests but we are killing them with dams, fish hatcheries, and straight rivers. For instance, dams are dropping the salmon down a 200-foot waterfall, pulling down hundreds of feet from the underpull. (Robert F. service Jan. 10, 2018, 2:25 PM, et al. "Pacific Northwest salmon are in big genetic trouble" 2018) Fish hatcheries are taking the genetic diversity away from the salmon along with putting them into the wrong environment.
Sediment erosion can affect coral reefs and oyster beds causing even more deaths. They also cause erosion on land, destroying most animal’s habitats and even leaving some islands underwater. Forests become destroyed and force animals to relocate, if they were able to survive the hurricane.
(Editing) The popularity the three cruise ships increased because of that, the marine environment is also affected. It can carry 4,000 passengers and crew. The garbage dumping and the untreated sewage at sea, plus the release of other shipping-related pollutants Dredging creates many major problems for reef. The drastic effects are caused by suspension of silt.The strongest effects are caused by suspension of silt, sedimentation, turbidity, oxygen reduction and the release of bacteria and toxic matter. A massive quantity of either coarse or fine particles will bury the corals, which are unable to withstand cover for more than one or two
