BIODIVERSITY AND EXTINCTION Biodiversity is determined by the variety of species extant in a specific ecosystem; this includes both animals and plants. Biodiversity is what gives an ecosystem a continuing and symbiotic relationship between all the organic and inorganic elements; maintaining the proper balance of different gases such as nitrogen‚ oxygen‚ hydrogen‚ carbon dioxide and many other elements‚ which differ in composition depending on the type of environment (such as subterranean‚ aquatic

Extinction is the end of an organism or group of taxa. Extinctions occur when a species becomes unfit for survival in its natural habitat usually to be replaced by another‚ better-suited species. An organism becomes ill-suited for survival because its environment is changed or because its relationship to other organisms is altered as stated from Credo Reference. The moment of extinction is generally considered to be the death of the last individual of that particular species. Mass extinctions‚ however

De-Extinction is one of the hottest topics in the science world currently and it tops the lists of conservation and genetic scientists alike for next big project. Though this could be a great way to learn of past species and finally see them for ourselves‚ at what cost is a species revived? The idea of bringing back an extinct species‚ such as some type of dinosaur‚ comes with many questions that most find to be debatable. Conflicts arise from every aspect of this “new” animal including how it is

Extinction of Dinosaurs Two-hundred and thirty million years ago the first dinosaur-like creature roamed the earth. Dinosaurs were a very successful and diverse group‚ dominating the terrestrial environments of the earth for 160 million years. The apparently sudden mass extinction of dinosaurs marks the boundary between the Cretaceous and Tertiary periods. Though there is not one definitive explanation to explain dinosaurs’ extinction‚ there are various theories that attempt to account for the

The Extinction of Baiji The Baiji‚ also known as the Chinese River Dolphin‚ are part of the family Plantanistiade‚ the river dolphin family. They had exsited in the Yangtze River in China for thousand of years. Nevertheless‚ the Baiji was recently declared extinct. The baiji’s demise can be attributed to over fishing‚ its lethal environment and the Great Leap Forward in China. Excessive and illegal fishing was a great threat to the baiji’s way of life. Electric fishing and the fishing method
