Supernovae and Black Holes Increase Radiation Changing Evolution

Evolution speeds up with cosmic activity. Most people assume that we are isolated here on this tiny planet called Earth. However, throughout the ages life has been impacted by what goes on out there in the cosmos. Humans would not be dominant in the world today - considering we got down to less than a hundred souls when the climate suddenly took a new direction. An arrow piercing a supernova? When astrophysical phenomena such as black holes send out x-ray flares it affects earthly evolution. It has estimated by computer modelling that two supernovas occurring close together increased radiation on marine life by a factor of three. This is a major change that nascent intelligent life had to adapt to. Radiation sends out muon particles which hit the ground. More of them alters the environment. DNA mutation will speed up, so evolution becomes more rapid. This would account for the sudden disappearance of established species and takeover by new ones. The dark clouded...

Fish Die in Poor South Australian Environment

Dead fish on South Australian beaches gives bad conservation image. When marine animals wash up on the shore dead what does a state government do about it? It tries do deny it and cover it up! Maybe it will stop in time - unfortunately it continues. The thousands of small fish dead on the beaches are bad enough, but dolphin corpses are found as well, even some penguins. The location is on the South Australian coast near the Port River, Adelaide.  Recently, a grieving female dolphin was seen nuzzling her dead baby, a terrible sight. A concerned PHD student, Nikki Zanardo, is investigating the issue. There is a worrying mystery here. Why has the state government sent dolphin samples to New Zealand? Tests could have been done in South Australia. If herbicides or industry poisoning is at fault, it will all come out eventually. You cannot hide anything today. It is not right that consumers are allowed to eat seafood when there is a possibility that dangerous biologic...

A Mermaid? No a Dugong!

Early traditional legends describe mermaids:  supernatural beings that lived in the sea, a combination of human and fish. As time went on, they were described as having a human body and a fish’s tail. But where did the mermaid legend come from?  For centuries, sailors travelled the oceans and returned to their homelands with tales of exotic creatures from distant shores, one of which was the mermaid. These sailors had been on the high seas for months. They may have been dehydrated, suffering from sunstroke, ill or simply lonely.  They saw creature with smooth bodies and long flowing hair swimming through the water. Mermaids! Of course to our eyes a dugong ( Dugong dugori ) does not look much like a mermaid. But to a lonely sailor with the sun in his eyes, these graceful aquatic human-like creatures could have captured the imagination. The long flowing hair was possibly sea grasses, which the dugong feeds on.  In an early record in his book, A Voyage to New Holla...

Ships' Ballast Water Spreads Marine Creatures

As international trade continues so does "equalization" of the planet. Many marine species are now found in all waters of the world. This is because transport ships literally hoover up animals in ballast water, which is released at any time, any place, when it is no longer needed. All ballast water is released into a port when cargo is taken onboard. Marine survivors of this rough treatment give the local environment a go. Some are successful and multiply to epidemic proportions. Zebra mussels and Pacific seastars in particular are a major problem. An Australian study gathered data such as ports where ballast was likely to be taken on and where it would probably be released. Marine species spread this way were identified and it was predicted how long they would survive. This data was fed into a computer. It was noticed that shipping volume was increasing mainly in the transport of primary products. Most of this Australian export was delivered to Asia and...

Shark Chokes on Sea Lion

Sharks are not the indestructible creatures many think they are.  There is a myth surrounding sharks that they are virtually made of steel.  They can bite through anything and withstand great hardship. A strong four-meter long white pointer was washed up dead on a Western Australian beach.  It certainly did bite off more than it could chew.  The cause of death was choking on a sea lion. There was no sign of any major injury to its body, just a large sea lion lodged in its throat.  It was observed jostling around in the shallows shortly before being washed up on a Coronation Beach, apparently trying to dislodge the sea lion. A man walking his dog first saw the shark and thought it was a diver.  There was an attempt to save the shark by towing it out to sea.  It was not known then what was the cause of its distress.  However, it later washed up dead on the beach.

Australia's Marine Resource

As fertile land becomes "all used up" with increasing demand for food we will rely more on the sea for nourishment, after we experiment with eating insects of course. Marine-based industries care little about the consequences of their actions at the moment. This has to change to make the oceans a renewable resource. Australia has the third largest controlled ocean territory in the world. This country has more responsibility than most countries. We allow nations to fish our waters but foreign fishing fleets seldom stay within the rules that are set. Overfishing is common. The Great Barrier Reef and Ningaloo are World Heritage Areas. We will have to protect and regulate more region around the coast of this vast continent. This may be selfish as we have a low population that enjoys to swim, dive, surf, sail and fish on an individual basis. However, with control comes responsibility. Australia's marine industry will rise from about A$40 billion to A$100 ...

Blue-Green Algae Causes Motor Neuron Disease

Motor Neuron Disease (MND) in not something that just happens to certain people with no hope of recovery. There is new hope about the cause and future treatment. It seems that the marine pest blue-green algae which grows in freshwater and saltwater is the cause. Apparently, it is more widespread than previously thought. It can be present in marine food that we consume and even in plant seeds. Like other toxins it moves through the food chain becoming more concentrated in species at the top of the line of consumption. It drastically changes the human body interfering with the way proteins function. The Australian research was based in Guam the place where motor neurone disease is the highest. People there have a taste for bats. When the food chain of these bats was followed it lead to the seeds of a cycad tree. Blue-green algae was found growing around the tree particularly on its roots. If a drug can be developed that can stop the toxin's action on the body's protein...

Global Warming Threatens Native Marine Species

As meteorologists tell us that natural disasters are becoming regular occurrences due to climate change, so the threat to certain animals species increases. Marine animals are in serious danger. The sea is warming up. It is accepted that whales beaching themselves is "normal". However, dugong doing the same thing is not. CSIRO which is always at the forefront of Australian research says that south-eastern and north-western sea regions around Australia have become significantly warmer. As some species move or even die out and new species arrive the ecological dynamic is disrupted. Death from new diseases becomes the norm. New species eat the food that native creatures eat, so marine animals that have been in the same place for thousands of years are doubly threatened. The future looks bleak. The climate could level off and remain changed but stabilize. On the other hand, change could be ongoing and the variation in marine species could decline. This could affect fo...

Bombs Dropped Near Barrier Reef

The Us has dumped bombs near Australia's Great Barrier Reef. It was not intentional. Two of their Marine aircraft were in fuel trouble and had to jettison the dangerous cargo for safety reasons. Before dumping the explosive devices they were disarmed. The planes were operating from a Navy ship. The now harmless bombs are sitting in a deep channel away from the Barrier Reef. They are in the Great Barrier Reef World Heritage area, however. Plans are under way to retrieve the bombs. Just how this is to be done is unknown at present.  It is not an international incident. The Australian government knows full well the immediacy of the action. There has been no protest. Removal will be done as soon as practicable. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot.com/atom.xml http://www.technorati.com/blogs/ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ...

Life Began on Land

Life may have begun on land not in the sea, Multicellular fossils, ancestors of marine life, lived on land. These were microbial colonies like lichen. Ediacaron fossils over 600 million years old have been found in South Australia. High-tech investigative technology showed the ancient forebears lived on land. The soil they were in had "old elephant skin' over it. This phenomenon forms in sandstone beds. It is much like the surface of modern sandy deserts with close wavy lines. Ediacaran fossils were direct ancestors of marine animals, not mammals. The chain of life leading to humans came during the Cambrian era long after these old multicellular fossils. Apparently, the presence of salt and even too much water are barriers to initial life formation. There was more animals diversity on land than in the sea during the Cambrian. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http:/...
