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.

Consuming More Tea and Coffee Prevents Diabetes - Doubtful

Claims about consuming certain things to improve health are way off beam. Every now and then supposed new research shows that if you eat this or don't eat that your health will improve. Years late we discover that the "experts' were totally wrong and your health was actually damaged. This happened with margarine, milk, eggs and so on. What is the latest? Well, apparently drinking up to three cups of coffee or tea each day reduces the risk of getting diabetes. Look around. Do you see people who drink these beverages regularly with diabetes? You sure do. There are thousands of them. The University of Sydney says “If such beneficial effects were observed in interventional trials to be real, the implications for the millions of individuals who have diabetes mellitus, or who are at future risk of developing it, would be substantial.” Their trials must be wrong. Surely millions of regular drinkers who have diabetes are thinking, "Why me? Why have I got the disease&qu

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
