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
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
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
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. Loggerhead turtles are being killed by people and I have a way to stop that.
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.”
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.
Incredible beaches, marine life, and weather are just a few of the things that make the Florida Keys an amazing place. The Florida Keys are a string of islands located off the tip of Florida, which protrude out into the Gulf of Mexico and into the Atlantic Ocean. The oceanography of the Keys are unique because of several factors, including the geologic history, the tides and waves, and the effects of natural and man made threats to the Keys themselves and the thriving marine life. The map below shows the stretch of islands and the many reefs that are right off the coasts of the islands (Florida Keys Map) Geologic History Thought to have emerged from ancient coral reefs or patch reefs that had eroded, the Keys are a bit of a mystery in terms
Everyone has their different beliefs about being an American. But how do one know about being American if they are not accustomed to being an American? In a story, read by Quebalea Green called Fish Cheeks wrote by a young girl at the time named Amy Tan.

Her family invited over their minister and his son that Amy had a crush on who were American.
Industrial fishing is the act of catching fish for a commercial profit. The fishing industry can be divided into sub groups of the different methods of fishing such as longlining, bottom trawling, dredging, and gillnetting. The list goes on as for the methods of fishing, but these are the main tactics. Longlining is a serious operation that is one of the top methods of industrial fishing. Known as “The Curtain of Death,” longlining consists of a main line that can run all the way up to fifty miles long that includes branch lines up to 1200 feet.
