Should Land Clearing in Australia Continue?

Logging is the process of removing jungle, forest, forest or grassland. The most common are Queensland and New South Wales. In the past 200 years, 70% of the Australian native plants have been removed, but most of them have occurred in the past 50 years. Between 2001 and 2004, about 6 million hectares of various ecosystems were harvested (http://en.wikipedia.org/wiki/Land_clearing_in_Australia, 2010). Despite soil salinity and greenhouse growth, the Australian land is known as "one of the world's most dry fertile continents", but has been in use for the past century. Organizing the land is still a problem. gas

In the prehistoric period of Australia, indigenous Australians used fire stick cultivation. This was the initial form of land clearing, which led to long-term ecological change. With European colonization, the logging of land continues to be done in large scale agriculture, especially cattle, cotton and wheat. Since settling in Europe, 13% of native vegetation has been lost. The extinction of 20 kinds of mammals, 9 kinds of birds and 97 kinds of plants is due to the logging of the land. Land purification is the main cause of Australia's greenhouse gas emissions, accounting for about 12% of Australia's total emissions in 1998.

Logging refers to cutting down trees, stumps and other obstacles as necessary to increase the area of ​​crop production sites on existing farms and to obtain logs and urbanization activities. Australia's primary forest area is approximately 164 million hectares, accounting for approximately 21% of the African continent (WWF 2007). As a result, 50 to 100 animals and plants have disappeared. Compared to poor countries, Australia carries out the fifth time of logging and cutting trees each year. The biggest threat to the survival of Australian flora and fauna is a massive exclusion of a mature jungle.

The most common type of vegetation today is the type of vegetation that adapts to drought conditions where the land has not yet been used for agriculture. The main vegetation type in Australia is 23%, which is a hilly area of ​​Western Australia State, South Australia State, Northern Territory. There is a eucalyptus forest in the east, acacia forest, forest, bush in the west. The grasslands are mainly distributed in the Queensland state. There are 55 kinds in Australian origin kangaroos and wallabies. Large animals vary greatly in size and weight, ranging from half kilograms to 90 kilograms. The main difference between baby's kangaroos and kangaroos is size - kangaroos tend to be smaller. Some people are as tall as a person, others are as small as a domestic cat.
