Geography: The Living World

1. MINING- MINERAL EXTRACTION

   Nota:

   • mining for gold and other materials to make money gold, copper + diamonds are found, cyanide is used to extract, only make $20 a day but they find it enough to live n, mechanised process to sift gold meaning larger areas are left exposed.
2. CATTLE RANCHING

   Nota:

   • raising cattle to be slaughtered 60% of land is cleared for cattle ranching, Brazil exports the most meat, 4,000 cattle a week are killed, it is cheaper to cut down trees than to buy new land
3. FARMING PALM OIL

   Nota:

   • extracted from the trees, used in make-up and other beauty products 50% of packaged products in supermarkets contain it, unsustainabe and damages trees.
4. SLASH AND BURN

   Nota:

   • forest gives oxygen, containing remedies for cancer, destroying land, CO2 produced, fires are uncontrollable 1?3 of deforestation is caused this way, 2 acres of land per second is destroyed, within 100 years all the rainforest will have vanished, makes land infertile.
5. ROAD BUILDING

   Nota:

   • building a road to promote eco-tourism and join two places together trans-amazonian highway is 2,500 miles long, greatest source of diversity on the planet, increasing income for local people and businesses.
6. RUBBER TAPPING

   Nota:

   • collecting latex from rubber trees 63,000 families earn a living by supplying rubber to the Brazillian government

Nota:

• spiders panda squirrel deer wildcats fox brownbear raccoon hedgehog beaver skunk monkey birds shrew badgers

Nota:

• At 30 degrees north and south of the sun, there is no clouds. So the full force of the sun is shining down. Becuase of not having clouds the high temperatures dissapear, making the nights extremely cold. There has been reports of frosts in the desert

Nota:

• Is a process by which salts from within the soil are deposited on top of the soils surface. Drawn out of the soil by the high levels of evaporation. It is also the opposite of leaching. Salinisation makes the soil too salty for many plants to grow and therefor inhibits human uses of desert areas.

Nota:

• this includes: -seeds which germinate, flower and die back within 24 hours -thick waxy skin to prevent water loss -needle leaves to reduce surface area and water loss

1. Subsistence Farming

   Nota:

   • The area is not very fertile. Soils are quickly drained, and contain few nutrients The farming is limited, typically a few animals on more grassy areas, and fruit.
2. Irrigation

   Nota:

   • Since the Indira Ghandi canal, commercial farming can take place. Irrigates areas near Jodhpur. Wheat and cotton can be grown. The canal also supplies drinking water.
3. Mining

   Nota:

   • Resources such as limestone and gypsum are found in this desert, and are valuable for the building industry
