Brink of Extinction In Malaysia today the survival of wildlife have taken second place to human activity. All major wildlife species are now threatened with extinction. Does saving these endangered species and taking necessary actions for those who are on the brink of extinction means anything to you? Most of us are not aware that our Malayan Tiger‚ Clouded Leopard (Roy Goh 2011)‚ Pygmy Elephant‚ Sumatran Rhino‚ Orang-Utan and Turtles are in the under-extinction animals category

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

Human Digestion Activity The digestive process involves the mixing of food‚ the movement of food through the digestive tract‚ and a chemical breakdown of large molecules of food into smaller molecules. The digestive system is made up of the digestive tract and other organs that aid in digestion. The digestive tract is a series of hollow organs joined in a long‚ twisting tube from the mouth to the anus. Those twisted tubes include the mouth‚ esophagus‚ stomach‚ small and

animals vs. Animals vs. humans There have been many debates about animals’ ability vs. humans in thinking and using language. The answer for this debate is no‚ animals are not able to use language and cognitive skills as humans do. When it comes to language‚ one has to distinguish between language and communication. Language is a system of communication that uses arbitrary signals‚ such as voice sounds‚ gestures‚ or written symbols [1]. Animals are not able to use language but they can communicate

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

Over the past 200 years‚ humans have made significant changes to natural environments all over the globe‚ and most of these changes have negatively affected wildlife‚ forcing unprecedented numbers of species toward extinction. However‚ extinction is a natural biological process that has been a part of species’ evolution since the beginning of time. Fossil records have shown that‚ even before humans were a part of the world’s biota‚ natural factors such as overspecialization ‚ competition‚ sudden

‘The Earth is experiencing a sixth mass extinction‚ brought on by the proliferation of humanity and its activities of production and consumption. ... The was in which the capital system operates makes a mockery of the necessity of economising. Indeed‚ it pursues everywhere with utmost irresponsibility the opposite of economy: total wastefulness. It is this profit-seeking wastefulness that directly endangers the very survival of humanity (and other creatures that share the planet with us)’ (Jone

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

In biology and ecology‚ extinction is the end of an organism or of a group of organisms (taxon)‚ normally a species. The moment of extinction is generally considered to be the death of the last individual of the species‚ although the capacity to breed and recover may have been lost before this point. Because a species’ potential range may be very large‚ determining this moment is difficult‚ and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa‚ where a species
