These include billions of tons of waste rock, very deep and wide open pits, high and long miles of dams, and the production of acid mine drainage, all of which can significantly affect wild salmon fishery. The pits can also become a breeding ground of mosquitoes that would cause illnesses to people living nearby. 2. Economic risks Pebble mining may open plenty of job opportunities, but it can also affect the other side of livelihood. A huge population of Alaska is heavily dependent on fishing, and the damage that pebble mining can cause to the fishing industry is likely to cripple a lot of people and communities.
Also, storms can destroy reefs, also often caused by humans affecting the environment. Around 50% of our coral has died, and this has a major impact on many other organisms, and the world in general. Many fish live in reefs, and need it survive, and this ruins the ocean, the most important part of the Earth. This comes back to hurt us as well. Eutrophication is a process in which excess nutrients
This shows that an environmental threat that blue crabs face is pollution because if about 1 million animals are dying each year because of pollution, we have a serious problem. Furthermore, another ecological hazard that this incredible animal faces is fishing and it’s equipment. According to the text, “Modern fishing methods have created some serious problems for the ocean. The populations of almost all fish species that we eat have shrunken,”(Dignan 14). This proves that another environmental threat that blue crabs faces are fishing because they may not be a type of fish, but, like most crabs, they are fished, caught and sold.
Zebra mussels are a big problem because they cost the economy lots of money, eat up almost all of the plankton, and they hurt aquatic life. My first reason we should rid of the zebra mussel is because they cost the economy lots of money. According to the article Zebra Mussels by MNDNR, “Zebra mussels can be a costly problem for cities and power plants when they clog water intakes.” They cost America 5 billion dollars a year just to replace things this small mussel has ruined. My second reason that we need to remove the zebra mussels
In fishery industry, fishermen are economically affected when their fishing gears and vessels are entangled or damaged by marine debris. This will impact the livelihoods of local communities because repairing these damaged facilities is highly expensive and time
As people have to be hired to clean up, and people not wanting to go to dirty beaches. Cost money to people working at the beach.This problem doesn’t just occur in the Persian Gulf, it occurs world wide. A study from the university of Georgia, February 3rd 2015, claims that about 8 million metric tons of plastic trash enters the ocean every year. Pollution in the Persian gulf is negatively impacting marine life, as oils spills occur, and ocean mining is at it’s peak, but most importantly sewage dumping. Believe it or not we are all a witness of watching someone litter, or us littering.
However, some countries are able to control their population growth, such as London, Greece, Japan, Singapore and Israel. Many problems are caused when you live in an overpopulated city or nation to its residents, such as environmental and social problems. Daily, 25,000 people die due to hunger and 18,000 of them are under the age of 5, because their country can’t provide them with enough food to feed the entire nation. One billion people lack access to water throughout the world, because of water shortages. Another issue with water is citizens are trashing their oceans damaging the water we drink and the fish we breed.
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.
Destructive fishing methods cause harm to the reefs because the dynamite and cyanide or other methods used because they break up the fragile coral reef are highly unsustainable. Unsustainable tourism generates a lot of income for the host countries, the tourists damage the coral reefs by careless swimmers and divers, and poorly placed boat anchors. Then there is also the problem with the hotels and resorts have a tendency to discharge untreated sewage and waste water into the ocean, which pollutes the water and helps the growth of algae, which makes it harder for the coral reefs to grow and expand. The growth of coastal cities and towns that generate multiple threats to the coral reefs that are nearby because with the expansion of the cities or towns there is limited space airports and other constructions projects are taking up the space that the reefs need to survive. “Coral reefs are biological assemblages adapted to waters with low nutrient content, and the addition of nutrients favours species that disrupt the balance of the reef communities” ( The International Coral Reef Initiative).
Causes and consequences The principal reason the ocean is contaminating is because of humankind, such as factories, trash, petroleum, deforestation, and other reasons. Most of our trash is made of plastic, it takes 1000 years to degrade, this material has killed thousands of animals per year, because they get intoxicated or affixed. The glass is another material that can kill animals of the ocean, some fish may get stuck inside the bottle and die because of hunger, others may eat broken glass and bleed out because in damaged its organs. If you eat a banana at the beach or any kind of fruit, there's no problem, this is biodegradable, this cannot hurt the ocean or the marine species, also this degrades so fast that it's still not dangerous
Businesses, especially smaller establishments in Kings Cross and the CBD have taken a massive hit as reports have come out saying that prominent and busy stores in these areas have been shutting down quite frequently. Dave Evans, owner of Hugos Lounge bar in Kings Cross said "We said it would destroy business, we said it would destroy staff," and later said. "And here we are.". This quote illustrates how the ‘lock-out’ and alcohol laws have negatively impacted local businesses as it puts many staff out of jobs and forced restaurants and bars to close down. The laws also negatively impact Sydney’s economy because the government is losing precious revenue from these businesses.
It’s not realistic because by doing that they’re exposing millions of people to the harmful toxins of the lake beds of the Sea and endangering wildlife. Accelerating the drying process is the last thing we need. Also, there is not enough funds for the long-term restoration of the Sea. The Salton Sea Task Force’s recommendation is to restore between 9,000 and 12,000 acres of shoreline habitat by 2020 using available state funds. Their plan is realistic because it involves using many the state has, which makes it a more obtainable goal in the long
Red Tide: How it affects Marine Life Red tide in Florida is a reoccurring problem that threatens marine life every year. Red tide in Florida waterways has a negative impact on marine life because it produces toxins that are harmful to marine species. It lessens the amount of oxygen in the water which ultimately leads to the migration and death of many different marine animals. Millions of dollars are poured into red tide research and prevention every year to help predict when and where a red tide is going to form. All the while, millions of dollars are being lost due to a drop in tourism and bans on fishing as red tide wreaks havoc on businesses and marine life.
