The arrival of the men to Australia was accompanied by new species, new animals, hunters that were the result of the brutal competition in the other continents.

Like Madagascar, Australia was also eventually discovered by man, though in this case much earlier. Man disembarked on the southern continent approximately 50,000 years ago.
When it arrived in Australia, our species brought with it powerful weapons of destruction that would bring an end to the peace and isolation of the island continent forever.
Man learnt how to use fire and acquired the destructive power of the storm and lightning.
New hunters brought new, more efficient and more deadly weapons.
And the arrival of the aborigines was accompanied by new species, new animals, hunters that were the result of the brutal competition in the other continents.
Australia would undergo major changes, but these came gradually and nature was able to absorb the impact. But today, when man is recovering his interest in and respect for the nature he has been destroying for centuries, Australia faces a new, invisible and devastating threat.
The world of modern man has an insatiable need for energy.
We have all become dependent on constantly growing energy consumption. The problem arises from an uncompleted process. Because we have learnt to obtain and use energy, but we do not know what to do with the toxic waste generated by energy consumption.
At first, we did not think this contamination was important, but the unstoppable increase in contaminating emissions is poisoning our world so much that its fabulous self-cleaning processes are unable to cope. Now, the contaminating gasses are changing the climate of the planet. And it is in places like Australia that we are starting to see the terrible repercussions this may have worldwide.
