Wildlife conservation is the practice of protecting endangered plant and animal species and their habitats. Among the goals of wildlife conservation are to ensure that nature will be around for future generations to enjoy and to recognize the importance of wildlife andwilderness lands to humans.[1] Many nations have government agencies dedicated to wildlife conservation‚ which help to implement policies designed to protect wildlife. Numerous independent nonprofit organizations also promote various

Australia Australia‚ to many‚ is known as a "classical country of immigration." All but about 300‚000 of the approximate 20‚305‚486 in Australia descended from immigrants who originally arrived with a settlement of British convicts in 1788. In July of 2001 Australia’s population consisted of approximately 92% Caucasian‚ 7% Asian‚ and only 1% Aborigine.(native Australian). Australia has an estimated net gain of one international migrant every 4 minutes and 9 seconds. As of September of 1999

There are over 4‚500 species of lizards‚ creating the most diverse group of Squamates‚ with each one having a unique biome it has adapted to. Lizards occupy habitats throughout North and South America‚ Europe‚ Asia‚ Africa‚ and Australia. They also live on many tropical islands in the Pacific‚ Atlantic‚ and Indian oceans. One of many of these lizards is the Flying Dragon Lizard that resides in the deciduous

Global Warming and its Effects What is global warming? Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide‚ water vapor‚ nitrous oxide‚ and methane) trap heat and light from the sun in the earth’s atmosphere‚ which increases the temperature. This hurts many people‚ animals‚ and plants. Many cannot take the change‚ so they die. However‚ global warming has its causes and it also has its effects on humans‚ and animals.

name is Ailurus Fulgens. The Red Fox‚ whose scientific name is Vulpes Vulpes‚ is from the Canidae family. They are both mammals and are the same size. However‚ the Red Panda and the Red Fox share similarities and differences in their appearance‚ habitat‚ diet‚ behaviour‚ reproduction and status of population. First of all‚ the Red Panda and the Red Fox are quite similar but a little different in their appearance. Like the Red Fox‚ the Red Panda has four legs‚ two ears‚ a black nose and two eyes
