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.
“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
The Negative Effects Captivity has on Orcas Orcas, also known as killer whales, have been captured and placed in captivity beginning in 1961. Not only were orcas captured and brought into captivity, many were born into captivity. An increasing amount of Orcas in captivity has started a serious conversation on whether Orcas are benefiting or suffering from being held in captivity. There are differing opinions about captivity having a positive or negative effect on the Orcas well-being. There are numerous amounts of negative effects resulting from orcas being captured and kept in captivity including: separation from pods, aggression towards other whales, aggression towards humans, a shortened lifespan, lack of exercise, tooth decay, lack of natural enrichment, unnatural reproduction, food deprivation, and the drugging of orcas.
On land, invasive species such as the wild boar are taking over Texas lands and hurting commercial industries. As conservationists, some of us are for targeting invasive species and some against. Mrs. Desonie states that “The number of alien species found around the world is growing exponentially as remote places become more accessible and
The Burmese python has become a predatory species in the Florida Everglades. The reason for this problem is the rapid growth rate of the species occurring all over the Everglades. The species have become pets and then thrown in canals. They also escape from zoos and move from other states because of the warm moist weather. The environment is an excellent breeding ground for the ever growing population of Burmese pythons in the Everglades.
In conclusion Blackfish is gives audiences a shocking, aggressive and deeply compelling look into cruel practices of marine parks for decades that will change the way you look at captive/trained killer whales and other animals. In watching this documentary has significantly opened my eyes regarding the brutal treatment and methods of capturing wild animals giving me a greater sympathy for orcas in parks such as SeaWorld. This startling documentary will surprise audiences as Cowperthwaite is unrelenting in showing the fatal consequences of keeping killer whales in captivity while also critiquing of the cruel and immoral practises of
Have you even seen or want to see a “superpredator?” If not, just go outside and look at the people around you or look in a mirror. Researchers have studied the hunting habits of birds, fishes, wild mammals, and humans. A new study shows that humans are very unique and strange predators. Humans prey and hunt adult animals in large numbers, unlike any other animal. Researchers warn that this style of hunting may push populations of those prey into decline.
In 2013, the documentary called Blackfish was released, a story about a killer whale that over the years at SeaWorld killed several people. It highlighted some of the major problems with animals in captivity. SeaWorld, known for having several different animal attractions; Dolphin Cove, Dolphin Nursery, Orca Underwater Viewing, Shark Encounter, Wild Arctic (Habitat) and many more. The organization first started with the intention of learning more about animals in order to educate the public about different behaviors of each animal. Trainers at Seaworld are offered the opportunity to get hands-on training with animals and are eventually are allowed to entertain the public with the skills they have acquired.
Large scale competitions can lead to serious problems for native fish populations as hundreds of fish can be taken out within a few days. Bringing bowfishing teams of 275 or more teams can destroy a lot of native fish populations in lakes and streams, which has a number of people concerned about the risk of native fish populations completely destroyed. Animal Rights Groups and Bowfishing Controversy One particular bowfishing tournament in Maryland was brought into the spotlight as bowfishers were hunting stingrays, but some of the rays happened to be pregnant. Each state does have separate requirements regarding the hunting of fish with bowfishing. In Texas, there are clear regulations about which game are eligible to be hunted with bowfish gear.
Worth billions of dollars every year, promptly following drugs, firearms, and human trafficking, animal poaching is the illegal act of slaughtering or capturing animals. Due to the approximated tens of millions of animals being poached for their fur, shells, horns, etcetera, there is a rapid decline in population, causing a myriad of species to confront endangerment and possible extinction. Furthermore, some of the most at risk animals include, but are not limited to, sea turtles, elephants, tigers, rhinoceroses, lemurs, and gorillas. This illicit trade is mainly generated by human avarice, the belief that some animal parts possess medicinal properties, and the lack of other livelihood opportunities. To place an approximated price on these
