Way of Life Severely Affected by Climate Change

Our grandchildren will not enjoy the natural environment as we do. Yes, visits are organized for sightseers, but at least we have something to look at. We ignore the damage we do at our peril. This couldn't care less attitude has to change. Water shortages will become normal in urban areas and country regions. Ironically, Australiasia is experiencing a lot of rain at the moment. Will this continue? Perhaps the nation is becoming more tropical. However, El Niño will return eventually. When the weather is hot, plants and people do not do so well. There is plenty of food available in Western countries now. This could change with a persistent drying climate. The West does not seem to care about those suffering famine in Africa. Starvation and malnutrition could happen at home. Animal and plant biodiversity also suffers from severe change. In the last decade 50 percent of native animal species have died out in Australia. When an organism meets its demise the whole ecosystem ...

Tasmanian Devil Resistance to Facial Cancer (DFTD)

Biological research shows genetic resistance to Tasmanian devil disease. The Tasmanian devil is an animal unique to Australia. It Once resided all over the continent. Perhaps is was easy for Aboriginals to catch for food. It cannot run very fast. It could just have died out due to a warming of the country. Tasmania is its only natural home today. Their raucous cries led to them being named devils by European settlers. They are violent to each other though attacks on humans are virtually non-existent. Scavenging for food is their number one priority. A facial disease began in the species in 1996. It was unusual in that it is the only known cancer transmitted from animal to animal. Tasmanian devil numbers fell by 80 per cent in twenty years due to Tasmanian devil facial tumor disease (DFTD). Extinction was predicted. However, it was noticed that some animals survived without getting the disease. Genes were examined and these devils had five genes not present in ...

Large Asteroid Craters Found in Australia

Australia has always been seen as remote. Yet new new things are being discovered about its history. It has been identified as the "target" of one of the world's largest asteroid impacts. Two craters found by Andrew Glikson and his team are thought to have been caused by a large meteor which broke into two pieces. Each crater is 200 kilometers in diameter. One of these craters on its own is larger than the impact in Mexico: the Central American collision wiped out the dinosaurs. It isn't the biggest, however. The Sudbury comet did a great deal of damage, but the world's widest crater is the Vredefort in South Africa. The twin craters in Australia have been flattened out over eons of time. They were found by geothermal research. It appears that asteroid impact covers the Northern Territory, Queensland and South Australia, a very large area. Seismic traverses is going to be applied next. This will hopefully bring new things to light. If the as...

Mass Extinction Has Begun

You may stop fearing an asteroid colliding with the Earth. Man himself could be the cause of the next mass extinction. People who harp on about climate change being a religion and an article of faith are like those who ignored Noah. Remember that humans got down a few hundred individuals in the past. We are very lucky to be here today. Of course the world would have gone on without us: it would be a very different world. There would be no pollution anywhere. Ebola is out of control. Antibiotics are failing. A world-wide plague could be on the cards. Danger to Man is not the only issue. Twenty five per cent of mammals could soon disappear. Forty per cent of amphibians are at risk. Because species are already dying off, a mass extinction could have already begun. The hottest decade on record shows that life is declining. When animals die off the food supply for other creatures also goes. So the path of extinction of predator species becomes real as well. Carbon is the...

Is Cloning of Extinct Animals Possible?

It seems researchers are close to cloning the woolly mammoth and perhaps a species of frog that gives birth to offspring with its mouth - swallowing fertile eggs then incubating them in its mouth. The frog died out in 1983. We have heard claims like this before. Personally, I believe we are a long way from being able to do this. Repairing the damage that pushed them to extinction is not sufficient to bring them back. Finding specimens with suitable preserved material is near impossible. Even the few frozen southern gastric-brooding frogs were not initially preserved with the intention of "cloning". Special techniques were not applied. It is thought improved systems like somatic cell nuclear transfer will enable creation of a living frog. Some presume this can be used on viable mammoth cells. The issue will be producing a healthy living creature. Previous research has resulted in incomplete clones: many do not live long. Most scientists are pessimistic about the poss...

Reserves Are Not Working: Extinctions Continue

Australia's slaughter of wildlife continues despite warnings from CSIRO. Nearly half of Australian mammals will end their existence very soon. Zoologist Fred Ford said 11 extinctions have occurred in recent years in the south-eastern forests of Australia. The reserve system is not working. They are just for show. Plants are doing well because they are surviving outside and inside reserves. Nothing is being done to protect small native mammals. Reserves are havens for introduced feral animals and invasive weeds. Rangers are not being trained to look after the endangered species. Money should be allocated more efficiently. With all the money put into reserves there must be more positive outcomes. Native animal need to be researched and the data must be analyzed. Records should be kept to formulate action. An astounding 65 per cent of reptiles in Australia have been discovered in the last 35 years. The public has not been adequately informed of this. http://www.adventure--australia...

Reptiles Are at Greater Risk of Extinction

Though there are worries over extinction of all animals, it is reptiles who are in most danger. Some reptiles are pretty, but for the most part they are seen as ugly. Because of this they lose out on conservation funding. This is serious with one in five reptile species predicted to die out. People are moving into previously pristine regions of the tropics to log valuable trees and to practice logging. The conclusion about endangered reptiles has been reached by 200 of the world's scientific experts. Funding is not enough. We need to change human behavior. This of course means changing human needs, which is more challenging. Concentrating on saving turtles is good for them. Other reptiles, however, remain at risk. The living and reproductive systems of many reptiles is still unknown. Out of sight, out of mind leads to extinction. Reptiles tend to live in the toughest of environments. Such specialization does result in their demise when humans change the habitat. Tho...

Death Adders Are Causing Their Own Extinction

Australia's death adder is contributing to its own extinction. Moving around to hunt their prey is not their method. An adder tempts its victims by laying in ambush and wiggling its tail tip. By wiggling its tail, however, it is noticed by cane toads, frogs and lizards who eagerly gulp down the tasty meal. After cane toads were introduced into Australia death adder numbers plummeted. Ironically as the cane toad attacks the snake it is bitten, so after its meal the cane toad dies - mutual suicide. Even if the snake eats the toad it will end up dead because cane toads are poisonous. For millions of years death adders have survived by enticing their prey within easy reach. Now this behavior is leading to their demise. Man cannot intervene to prevent this. There is nothing that can be done. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/blogs/ http://adventure--aust...
