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

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 and Evolution Ecology helps us understand the importance of mass extinction in evolution‚ and it also helps us understand some of the causes of extinction. Ecological niche is one of the most important concepts to understand. An animal or plant lives in a certain place is active at a particular times‚ and eats certain things; all these factors describe its ecological niche. Our environment is parted into millions of ecological niches‚ each that represents a probable home for life

GMO’s inside a lab and work to expel the uncontrolled production of GMOs‚ because of the fact that the genetically modified organisms can interact with the environment and cause the transfer of harmful genes which can lead to the elimination and extinction of all natural organisms. It may not be a well known fact but GMOs have greatly increased our quality of life. GMOs have mainly helped our agricultural industries by increasing the size and the quality

Animal Extinction - the greatest threat to mankind In the final stages of dehydration the body shrinks‚ robbing youth from the young as the skin puckers‚ eyes recede into orbits‚ and the tongue swells and cracks. Brain cells shrivel and muscles seize. The kidneys shut down. Blood volume drops‚ triggering hypovolemic shock‚ with its attendant respiratory and cardiac failures. These combined assaults disrupt the chemical and electrical pathways of the body until all systems cascade toward death.

reasons as well as argument for necessity of conducting such campaign. First of all‚ the environmental degradation is widely recognized as a primary reason. In fact‚ the deforestation and environment pollution have put creatures on the verge of extinction. Domestic apes in Vietnam‚ which have die out due to shrinking of tropical trees‚ could be taken as a particularly salient example of this. Ignoring the impact of human on minimizing the habitat of animals is thereby a grave mistake. Additionally

numbers of endangered species are still increase rapidly. However‚ there were still numbers of selfish people that did not even concern about the animal species that disappeared. Animal extinction can be defined as animal species no longer stay in the earth as it already disappeared. The factors that lead to animal extinction are irresponsible human’s hands that destroyed animal’s habitat by deforestation‚ illegal wildlife trades and climate change. Deforestation is the main causes that lead animal species

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
