Red is the endangered areas In image 2, the most endangered reefs are in areas that are considered “Third World”, where populations have limited access to education. The people here are concerned mostly with putting food on the table now, later can wait for another day. There is a problem with reef systems today that directly comes from people who probably did not know that they were causing it. Runoff from sewers, especially untreated sewage kills corals by: * Suffocating corals and zooxantheallae by covering them with sludge and cutting off
Most of the impact of this was experienced by the marine species. Eight U.S. national parks were threatened and more than 400 species that live in the Gulf islands were at risk, including the endangered Kemp's Ridley turtle. The clean up of this travesty cost the government and companies billions to clear. As a result of the spill deep sea drilling in the Gulf was suspended until new safety measures had been put in place, costing governments and companies further millions, whilst the price of oil continued to rise. A spill in other deep sea areas such as the Arctic could accelerate damage in a very sensitive environment, which is already dangerously close to its
These runoffs have contributed to the beach closures, and the unsustainable condition of biological life in the lake. Human health is at great risk due to the untreated waste that is dumped in Lake Huron each year. The untreated sewage contains many viruses, two being Giardia (an intestinal parasite), cryptosporidium, which causes intestinal illnesses and even death. E. coli a more familiar virus has elevated its concentrations in Lake Huron, found in either animal or human feces, which causes diarrhea, nausea, and stomach cramps. ("Testing the waters,"
It was literally a dumping ground and it even caught on fire a few times due to the toxic wastes. The phosphorus levels in Lake Erie are increasing due to the pollution causing harm to the fishes that reside in it. In 2014, Lake Erie had so much algae from pollution that it caused the City of Toledo to be left without fresh water. This algae was caused by the excessive amount of phosphorus in the lake. This excessive amount of Phosphorus is caused when the fertilizer is dumped into the lake by farmers.
“Apparently the mass of the plastic particles is six times more than the mass of the natural plankton in the area.” This large expanse of ocean has become unhealthy for the animals that feed around the Gyre. “The plastic is found at depths of up to 30 meters. It is literally creating a landmass.” Because not all the plastic’s as it breaks down, and releases large amounts of toxic substances into the water of the Pacific Ocean. Not to mention that the Sea birds and other marine animals mistake these sand like plastics as food, and aren’t able to digest the plastics resulting in a large number of deaths of these animals. We all can contribute in helping the slow the growth of “trash Island” so some call it.
Not only is the water unfit for human consumption, it is now destroying the marine ecosystem and this is serious business when you consider how important the ocean's health is to human survival. The level of mercury found in tuna and salmon has already resulted in warnings about how much to consume because it is threatening to our very life. Close
Aquatic Invertebrates: Adaptations and Feeding Guilds INTRODUCTION Global warming and human's authoritative influence on the environment such as deforestation, pollution etc. are taking a bad toll on the diversity of the ecosystem. Global warming which has brought about increase in the temperatures is disturbing the natural cycle of the ecosystem. This has brought upon an increased droughts throughout the world. The droughts and increased heat has had negative impacts on local aquatic invertebrates.
And although they offer financial and technical support, there are still problems on the Northern Beaches coastline. The erosion on Collaroy Beach is one of the worst cases in NSW, and without efficient action the problem will only get worse. In 2002 the Warringah council proposed to build a seawall on the beach. This was met with much criticism from the community, mainly due to the fact that a seawall would destroy the beaches natural beauty, something that no one wants to see. The designs for the sea wall cost roughly $100,000, and to build the wall would cost upwards of $11,000,000, of which 40% would be paid by the homeowners of Collaroy.
For many decades, water pollution has been a major environmental issue. "Water pollution is the contamination of water bodies and occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds" (Wales). Lake Huron, which is known as the third largest of the lakes by volume of Great Lakes, (Lakes Huron) water quality has been of major concern. Few major sources identified were faulty septic systems and agriculture. Some of the effects caused by the pollution included: disruption of aquatic life, elevated levels of nitrates and phosphates from polluted underground water, swimming prevention, and numerous outbreaks of Avian Botulism.
Fluctuating conditions of their habitat has led to a massive population decline. “Saving the smelt” has ignited tremendous controversy over the measures considered for saving their species. When considering the deep ecologist perspective, there is an obvious need to assure the safety of the delta smelt, despite the negative effect upon the economic standing of those dependent on water from the large pumps of the estuary. Efforts to protect the endangered fish from further decline have focused on limiting or modifying the large-scale pumping activities of state and federal water projects at the southern end of the estuary. Recognized by many as the “smeltdown in the Delta,” the extinction trajectory of delta smelt, has left the once-abundant species in critical condition due to record-high water diversions, pollutants, and harmful nonnative species that thrive in the damaged delta habitat.
