The world Contamination Contamination is made by the human being. It's common in the world but really bad for the world because bad things can happen like: global warming , animal extension and contaminating rivers. No one is perfect but we can try to clean up the world and get to work .All chemicals contain some level of impurity. Contamination may be recognized or not and may become an issue if the impure chemical is mixed with other chemicals or mixtures and causes additional chemical reactions. The additional chemical reactions can sometimes be beneficial, in which case the label â€˜contaminantâ€™ is replaced with reactant or catalyst. If the additional reactions are detrimental, other terms are often applied such as toxin, poison or pollutant depending on the chemistry involved. A major fraction of chemistry is involved with identifying, isolating, and studying contaminants.
Recent animal extension Thylacinus cynocephalus, Greek for "dog-headed pouched one") was the largest known carnivorous marsupial of modern times. It is commonly known as the Tasmanian tiger (because of its striped back) or the Tasmanian wolf. Native to continental Australia, Tasmaniaand New Guinea, it is thought to have become extinct in the 20th century. It was the last extant member of its family, Thylacinidae; specimens of other members of the family have been found in the fossil record dating back to the early Miocene. The thylacine had become extremely rare or extinct on the Australian mainland before European settlement of the continent, but it survived on the island of Tasmania along with several other endemic species, including the Tasmanian devil. Intensive hunting encouraged by bounties is generally blamed for its extinction, but other contributing factors may have been disease, the introduction of dogs, and human encroachment into its habitat. Despite its official classification as extinct, sightings are still reported, though none have been conclusively proven.
Recent animal discovery The Smithsonian National Museum of Natural History in Washington DC, USA, has announced the discovery of the first new mammal species in the American continent for thirty-five years. Native to Ecuador and Colombia, the olinguito belongs to the raccoon family and looks like a cross between a little bear and a cat. The olinguito is not unknown to mankind - until now, in fact for the last century, it has been identified as one of a number of types of olingo, carnivorous animals living in trees in South America... but today it has been classified as a distinct species. The discovery was publicized by the scientist Kristofer Helgen, the curator of mammals at the Smithsonian National Museum of Natural History in Washington DC, USA in a work carried out by himself and his team, published in ZooKeys.
