This is concerning for a couple of reasons. First, it has a tremendous negative impact on the marine ecosystem. Species are being taken away from ecosystems, in some cases even being depleted to near levels of extinction. For example, the same UN report reveals that, worldwide, nearly 90% of predatory fish stocks are gone . That means that most of the world is losing
With such great numbers these species are responsible for the extinction or near extinction of several hundred native species. The Nile perch can cause substantial damage due to its appetite for creatures that support their ecosystem. Another example of an invasive species is the Asian tiger mosquito
The film, “Jaws”, especially, has altered people’s view on sharks and sees them as the real monsters that still exist in the world. People tend to see no benefits in saving sharks since they are seen as monsters, so as humans, people kill sharks before the sharks kill them. (“Shark Trust – Shark
Invasive species alone, have a stronger negative affect on biodiversity than forest clearing, disease and pollution combined. For example, the Nile perch is a species of fish that was introduced to Lake Victoria as another resource for food. This new non-native fish quickly became a devastating predator and has eliminated over one hundred species of fish. The Nile perch was able to do this because they reproduced rapidly and they could out compete native fish for habitat and food. Invasive species are aggressive species that can control a newly introduced ecosystem by spreading quickly and taking over the
Many of the introduced trout resulted in the disturbance of local ecosystems through the competition with or preying upon indigenous fishes. Rainbow trout has been blamed for driving many native species into extinction or endangerment. They have eradicated frog species and threatened many native fish species in a variety of environments, such as the Californian golden trout and humpback chub in the Grand Canyon. As established, eliminating or diminishing aquatic species in a given habitat can have drastic impacts on the entire
“Over 200 fish species have been introduced to the United States following importation, many of which threaten ecosystems and infrastructure” (103). When exotic animals are introduced to habitats they did not evolve with, they are without many of the environmental stressors that are placed on native animals, such as predation. When that characteristic is coupled with the fact that some exotic animals may be larger and more aggressive than its ecological counterpart, it becomes easy to see how non-native species out-compete native
That is not cool because this may kill the population and do you want to be known as the man who killed the rest of the Loggerhead's. Many people are killing turtles or disturbing them. It is wrong to disturb Loggerhead turtles in their nesting. My reason for that is they may get scared and leave their babies alone. It is also very wrong to kill Loggerhead Turtles.
The Everglades used to be a beautiful place that was home to many rare endangered species. But thanks to construction, agbusinesses, and draining the Everglades we have destroyed this one beautiful piece of land. To lead off, a mass increase in construction around and in the Everglades lead to a total destruction of it. In “ The Florida Everglades ” it says “ The construction cuts off the flow of fresh water to the Everglades.” Without the flow of fresh water to the Everglades fish wouldn 't be able to live, the Florida Bay wouldn’t be able to survive and we wouldn’t have clean water to drink. On page 113 paragraph 1 it states “ These wetlands were once home to many rare, endangered, and exotic species.
Other invasive species may not destroy the habitat, but it can have an impact by killing large numbers of other species. Burmese pythons, for example, are top predators in the Everglades. As such, they have local mammal and bird populations. They are capable of consuming deer and even alligators, these creatures eat virtually any animal they encounter in the Everglades. A number of threatened and endangered bird species have also been found in the digestive tracts of pythons, prompting concern that they could drive some species toward extinction Lampreys in the Great Lake parasitize native fish.
An example of this species is an Zebra Mussels. Zebra mussels are invasive can kill native freshwater mussels in two ways the attachment to the shells of native species can kill them. Another way these species can outcompete native mussels and other filter feeding invertebrates for food. Zebra mussels are from Eastern Europe and Russia. They were brought over to the great lakes in ships.
