The Oxford dictionary defines extinction in relation to biology as a species, family or a large group having no living members (Oxford, 2016). With the estimation of the four billion species that evolved on earth during its 4 billion year existence, about 99% of them now are extinct (Novacek, 2001). This displays how natural extinction is, but it is usually stabilized by speciation (Barnosky, 2011). A major extinction event is one in which many species meet their end over a short period of time, these events are grand in scale and many species of all ecological types (i.e. animals and plants, aquatic and terrestrial) all around the world are involved (Benton, 2011).
In the US alone, the Office of Response and Restoration of the National Oceanic and Atmospheric Administration (NOAA) responds to over a hundred oil spills each year (NOAA). While spills happen on both land and water, ocean spills are much more difficult to contain and recover from. They happen easily, almost too easily, either caused by carelessness, accidents, or natural disasters, and their negative environmental impacts could take decades to recover from. It seems like as long as humans are still depending on oil, spills will continue to wreck havoc on marine life. Oil harms marine animals both physically and chemically.
A pressing social problem prevalent in the world today is the destruction of marine habitats which leads to the loss of food for humans. I am going to discuss the many causes of the deterioration of the marine habitats such as development, chemical run off into water supplies, bottom trawling and dams. “Habitat loss in these areas have far-reaching impacts on the entire ocean 's biodiversity” says National Geographic (2014). Our population is growing at an exponential rate; according to National Geographic (2018) they predicted that by 2050 (which is only 32 years away) that the population will grow by 2 billion more people. This means our planet will need to sustain 9 billion people.
Falls are the leading cause of death for the construction industry in the U.S. On average between 150-200 construction workers die each year from falls. More than 100,000 workers are injured annually from fall accidents at construction work sites. This number is unacceptable and shows the importance of fall protection, prevention, and proper training is to saving lives and reducing injuries. On average between 150-200 construction workers perish each year as a result of fall accidents. More than 100,000 workers annually are injured because of fall accidents.
Marine conservation has become increasingly important with the size of the human population exceeds seven billion people, and the negative effects on the human world 's oceans rise (Roberts and Hawkins 1999). There is growing recognition that marine species could be vulnerable to extinction, and there are already many organisms have already been confirmed extinction (Vincent & Hall 1996, Roberts & Hawkins 1999, Reynolds et al. 2002). A recent compilation of 133 known local, regional or global extinctions of marine populations found that exploitation is the most common cause (55%), followed closely by habitat loss 37%, (Dulvy et al. 2003).
Despite the benefits of tourism and associated infrastructure development, the constant presence of people at beaches and the destruction of the coastlines modify the living environment of the sea animals and negatively affect their ecosystem conditions for survival. Increased tourists flow also necessitates overexploitation of sea resources to provide special meals and diet. Likewise, tourism opens a way for shipping activities, which eventually cause oil spills and rubbish dumping (Huang, 2009). Thus, it is apparent that tourism and related developments such as intensified fishing activities significantly endanger sea animals around the globe. The last reason, is that the oceans and seas are a good place to throw wastes in some perspective.
SCOPE AND RATIONALE : In this research, I would be analyzing the reason for increase in water pollution both global and locally. How this pollution affects our life; why people don’t care about preserving this precious Natural resource and what are we doing/treating it now. I personally, want to know how an individual can do to protect our planet against all this pollution. INTRODUCTION: Water is life, with almost 70% of the earth’s cover being water; it undeniably becomes one of our greatest resources. But the heart-rending news is that today, it’s Infested with waste ranging from floating plastic bags to chemical waste, our water bodies have turned into a pool of poison.
[Type text] [Type text] [Type text] 1 Human Impact on Water Human Impact on Water ENV/315 Human Impact on Water The health and quality of the water and aquatic ecosystems in and around the Tox Town Port continue to deteriorate year after year; the high traffic of cruise ships in the port, the excessive industrial and urban runoff and the contamination from septic systems continue to alter the chemical balances of the water. Algal Blooms caused by human activity, along with the mismanagement of fisheries also alters the coastal environments and introduces more pollution into the Tox Town Port. The state of the port further depicts that while natural events can pollute and alter water bodies, the actions of humans are in fact more detrimental to the health of aquatic environments. Water Pollution Sources Cruise ships in the Tox Town Port represent one of the main sources of water pollution: The ships continue to increase in size and carrying capacity, which only increases the amount of sewage, wastewater, and garbage created by not only the ship but the passengers aboard the ship as well. Virtually all the waste created aboard the ship will be discharged into the port, not only polluting the port water, but also contaminating the fish and other marine life populations (Tox Town, 2015).
Pollution of water by wastes from producing plants and by sewage of metropolises finished the work of obliteration by now commenced by heedless fishermen, but the contamination of the water is distant extra weighty than over-fishing. Seals are extremely sensitive amid the marine mammals that amass toxins in their blubber. Marine mammals that rely on blubber to manipulation body temperatures amass higher level of toxins. As animals possessing blubber have elevated number of obese, elevated number of toxins become amassed in the blubber marine animals. Countless toxins become stored in fat.
Pollution is a big problem around the world that affects at least a thousand of animals,marine life and also causes global warming.Pollution can cause death or serious problems and diseases.A article Bios Urn states that “8.9 million people are killed a year from pollution”.It also says that 200 million people suffer from pollution.This shows why pollution is a really big problem. In this essay we are going to see how pollution affects the environment and the ecosystem.In addition to how pollution affects animals,plants, and marine life.Finally,how pollution affects human health. To begin with, pollution affects the environment and the ecosystem.Pollution has a big impact on the environment and the ecosystem because it
