SOSE ESSAY – BIOMES
• It has been suggested that food production has changed some biomes in Australia, from natural systems to systems completely dominated by humans.
• In the following essay a number of points will be discussed to show my support of this statement. The following paragraph will discuss the definition of a biome and examples of these in Australia will be outlined.
• Following this food production in Australia will be discussed and the effects this has had on the land.
• In the next paragraph the impacts of this farming will be outlined and possible solutions discussed.
• Finally, in the last paragraph my opinion on the above statement will be addressed.

They are multi-layered with trees being a variety of ages and are biologically diverse which makes them home to rare or endangered species. They show signs of natural regeneration and decomposition.
• The desert biome environment has temperature extremes. Deserts can have a variety of different landscapes like being dominated like the Simpson and Great Sandy Desert, or can be mainly smooth and flat, like the Nullabor Plain and Barkly Tablelands. The Gibson and Sturt Stony Desert, which contains low rocky hills. Spinifex and acacia shrubs can dominate some areas of deserts.
• Water has been diverted for farming. This could include the production of food crops and cotton. This water has been taken from nearby wetlands and rivers to areas that were previously drier and used as irrigation for the farms. For example, the Murray-Darling Basin contains 40% of farms in Australia, which means that three quarters of Australia’s irrigated crops get their water supply from either the three main rivers: the Darling River, Murray River or the Murrumbidgee River.
• The savanna biome is mostly grasslands, which is ideal for agriculture for animals to graze on. A common threat to grasslands is over grazing which puts the biome at risk and makes it very fragile. Farmers have taken over the land, introduced new systems that have caused some species of plants and animals to become endangered.
• Seagrass meadows have been reduced in area due to the effects of industrial development and sand mining.
• Old growth forests are being logged, which reduces biodiversity.
• Desert biomes aren’t very useable for agriculture due to the temperature, soil fertility and water. The soils in the northern parts of Australia are very old which makes them infertile for growing. That’s why cattle farming dominates in the area.
