Agriculture Disrupts the Ecosystem

Human impact on native flora and fauna is real. There seems to be no way the detrimental affects can be ameliorated. Aboriginals have been in Australia for 40,000 years. apart from the unanswered question about extinction of mega fauna Aboriginals did not alter the external environment at all.

Sedentary agriculture is the major contributing factor to habitat damage. Planting mono-crops seriously changes land features. In Western Australia, for example, water points are located at 50 sq km on average. In its pre-European natural state water holes could be found 2.5 sq km apart. This is serious change with species of native birds declining.

Unless we set areas aside as pristine, protected sectors only introduced pest species will remain. Even without the pest birds, the proportion of native birds is altered. Some die out while others increase in number. The ecosystem is no longer in balance.

Anthropology Has New Theory on Australian Aboriginals

New theory on Australian Aboriginals - Anthropology. Australian Aboriginals split from Eurasians and moved south into the dry continent. Twenty thousand years later the world warmed up and Australia was cut off from its northern neighbors. This is the latest theory.  But when Europeans initially came to Queensland there were two types of native people. Each was a distinct genetic pool. One was like Papua New Guineans. The other was very slight and shorter. It is the latter that predominates today. Papua New Guineans Australian Aboriginals Some scientists still hold that there was only one move out of Africa. This is an unsustainable supposition. The doors for movement were always open. Australian Aboriginals were quite unique. It seems that they were the first to leave Africa. There is also the question of Tasmanian Aboriginals who were wiped out by arriving Europeans. There is no evidence of them now. They could not light fires. The flames had to be stolen f

Beatboxing - Percussion Sounds of the Mouth

There must be a dearth of things to study. Scientists are now researching the odd sounds that people make. It may seem weird but its true. Those who can make odd sounds are called beatboxers. Scientists are interested in percussion sounds. These are expressed in Celtic, Chinese, North American and Indian cultures. Hip-hop is an area of great interest. A young "practitioner" had MRI scans done on his mouth while he created percussion sounds. The conclusion reached is that a lot of brainpower is involved in imitating percussion. It "is a small part of the larger puzzle," experts say. In my view it takes little mental concentration. Just put your tongue behind you top teeth a "tap" away. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot.com/atom.xml http://www.technorati.com/blogs/ . . . . . . . . . . . . . . . . . . . .
