Bush fires:

-Problems: -high damage in settlements and at the infrastructure

-ash foul the still standing drinking water reserves

-put out the fire as fast as possible

-to stop spread (Skizze an Tafel)

Water shortage:

-Problems: -waste of water

-people want luxury:

- Normaly the trade wind blows the warm water, which is relevant for the rain in Australia, from west of south Amerika between Indonesia und Australia. Every 2nd to 7th year appear the weather phenomenon 'el Nino': That means

the trad wind stops and there's no warm water is in Australia. No rain in Australia and to much rain in South Amerika

-Removal: -sing forbidden under shower

-government tries to make the people wast less water

-alternative Wasser winning: from saltwater

-Use of sewage and rain ( % of aren't used)

-Inhabitants of big cities like Sidney it isn't allowed to water the gardens during the dry season

Dying out of native animals:

Danger of the Great Barrier reef: Problems: -climate change

-oil layers

-hudge sea stars ( 0 cm diameter, 0 Kg heavy)

-environmental pollution

-deletion by trawls

-pollutants from the canesugar farms

-hunt of sea stars

-corals form them on their own:

-mucosa against heat

Danger of Fauna:

-to much tilth

-sequences are erosions and barren soil

Remaval: -nature reservationes

-forbidden of logging animal problems:

Problems: -grashoppers eat hole areas

-camel plague (ca. 1 million) damage Aborigines, ruin hole areas and transmit dangerous maladies

-toxic toads (ca. 0 Millionen) eat all on there way. By the poison died even people and big animals like crocodiles

-to much cranes, connes and camels

Removal: -against grashoppers are pesticide used

-hunt of camels-people had to kill the toads with all they have, for example                 croquet mallets

My opinion: I think most of the problems are not so , because they are self made and so they could even remove it on their self.

And when all people, not only the Australian, be careful with the nature and protect it are the problems solved.
