connections between different species. Scientists of our day have spent a great deal of time categorizing species into a variety of sub-species‚ genera‚ orders‚ classes‚ and kingdoms. There must be similarities that scientists have agreed upon if they have decided that they would group them. We places species of similar body or bone structures near each other in their organization. These are perceived connections‚ regardless of our perspective on the origination of these species. The difference between

Elephants Just in the past 10 years‚ ten thousands of elephants have been slaughtered. Sometimes the killers don’t wait till the elephants are dead to take the ivory. This causes the elephant to suffer greatly. Elephants are endangered. Many baby elephants are killed for their tiny stubs of ivory‚ how to save them‚ and the origins of elephant abuse. Some devastating facts about elephants are that they have been dropping 62% over the last decade. (Pg1) About 100 African elephants are killed a day

Imagine your favorite animal going extinct. What if it was all because of one thing‚ trophy hunting. Would you still be a fan of trophy hunting? The revenue isn’t used properly‚ rules and laws aren’t followed‚ and endangered animals aren’t protected. There are also so many more reasons‚ the list could go on. Trophy hunting should be banned EVERYWHERE! To begin with‚ trophy hunting should not be allowed because revenue isn’t always used properly. According to “Africa’s Uneasy Neighbors‚” “only 3%

We should take a precautionary approach and restrict the importation of non-native species there is the risk that some of these species can become invasive. There are multiple instances where a species was introduced to its non-native range for recreational purposes and eventually ended up becoming invasive. The feral pigs in Hawaii were intentionally introduced by Polynesian explorers. When Polynesians returned to Hawaii‚ the settlers had something to hunt and eat. Since the pigs’ arrival‚ they

predators usually predate both the animal and their eggs (Hernandez et al 1997). Last but not least the biggest predators these animals face are human. This comes in many different forms such as urbanization‚ mass agriculture‚ introducing invasive species‚ and directly hunting or killing these animals. With their cryptic behavior discussed earlier Texas Horned Lizards are often run over along roadsides while thermo regulating (Moeller et al 2005). Hunting is historically known for causing the demise

Ever since the devil facial tumor disease (DFTD) emerged in the mid-1990’s‚ the Tasmanian devils’ population has been on a rapid decline. As these devils are a keystone species of their ecosystem‚ their decline has allowed non-native predators such as cats and black rats to flourish and decrease the number of native prey. This effect is an example of the top-down keystone predator hypothesis. Due to the downfall of the devils‚ Australia’s once most intact faunal communities has diverted into an invasive
