All throughout Africa the economy is slowly and rapidly by the effects of poaching. Poaching is decreasing the number of animals that roam the plains of Africa and also affecting the villages in the plains as well. The African fish hatcheries are some of the places that are economically impacted by poaching. Poaching is one of four exploitation factors that affect the fish hatcheries but poaching is one of the main problems in the system. The poaching over the years has greatly affects the yield of aquatic animals that the hatcheries have been receiving.
The reason I don’t think that the consumption from predators is why the population is declining so rapidly is the fact that these predators have been hunting these fish for hundreds of years. It wasn’t until humans came into the picture that the population started to shrink. The predators now have to compete with us for their food. The magnitude of over-fishing is often overlooked and the rapid growth in demand for fish and fish products is leading to fish prices
The Gharial there is less than 400 and the adults of the critically endangered gharial survive in the world today the gharials, which once almost became extinct and then the Gharial helped to boost of population and a critically endangered species.and year and than 2,000 gharial the crocodiles and the (Gavialis gangeticus) hand Hatched and then importantly, and more than 400 adults and the critically endangered gharial and the survive hand world today . Gharial,and they are almost became the extinct because the hunters for the valuable and skins, are today. The gharial (gavialis gangeticus), also the gavial the fish-eating. Crocodile, are the crocodilian that Family gavialidae,that native are from northern part of Indian Subcontinent. My endangered
At one time, as many as 500 species of cichlids existed making Lake Victoria one of the most diverse lakes in the world. However, the number of cichlid species has now plummeted to just 200, mainly due to the Nile Perch. A side effect of the loss of cichlid species is that a significant number of them feed on detritus. With declining numbers of cichlids to feed on detritus, more unconsumed
The continuation of unrestricted fishing will worsen world hunger among impoverished coastal communities, many of whom depend on the abundance of fish to feed themselves and their families, and result in ultimate environmental chaos and the extinction of thousands of In recent years, the demand for fish, a healthy food rich in omega-3 fatty acids and lean protein, has sky-rocketed. This is in part due to increasing demand for healthier sources of protein in wealthier nations. In fact, the amount of fish in the oceans has significantly decreased. The New York Times reports that, “according to commission figures this year, 63 percent of stocks in the Europe’s Atlantic water are overfished” and “83 percent of its Mediterranean stocks” and some “2/3 of its Baltic stocks” (Jolly, 2011). In the more recent years, fishermen have discovered ways of fishing that give the fish no chance of survival.
"More than 60 percent of the original African rain forest is gone." (Pulsipher) As well as depleting their rain forest Africans are cutting down their dry forests as well to make way for farmland and fuel wood and other settlements. Not only are they clearing their lands but they are grossly depleting the fish populations off of their coasts. THe wildlife which provides the protein, medications for the prevention of diseases, and revenue from tourism are becoming severely threatened by habitat loss. Desertification is spreading and water supplies are decreasing at an a rate faster than nature can replace it.
(Eoearth, 2008). About 20%of the original area of coral reefs has been lost, with a further 25% threatened in the next century (WMO, 2010). Coral reefs provide human societies with huge benefits. This can be seen though the protection they provide against storms, as well as their economic benefits for the fishery and tourism industry. Coral loss and reef degradation will have dire effects on family incomes as well as local economies.
Approximately 30% of species will become extinct by 2050. Changes in one population will have effects throughout the entire food web. For example, temperature fluctuations reduce plankton population. The North Atlantic whale feed on plankton as their main food source. A reduction in the plankton population will
Over fishing occurs when there are more fish caught than fish in the ocean to sustain fish stock. Global warming is another big harm to the ocean. Global warming affects all of the earth. Animals are having a hard time surviving because sea levels are rising and ocean temperatures are changing. The sea animal cannot adjust to these changes in the ocean due to global warming.
ABSTRACT Coral reefs ecosystems have drastically changed over the past 40 years. The main reasons for the decline of coral reefs is due to weather and temperature changes, too much pollution, boats, and overfishing. As a result, coral reefs are considered an endangered species. Over 50% of the people in the Florida Keys rely on the coral reefs in one way or another. Many don’t realize that they provide humans with a source of income and more importantly, life for a wide diversity of marine animals.
