the world is just Awesome
the earth and above
-we had 3 billions people depend on wood and the main source of energy.
- we have been known the amazonian rainforest and the Amazon lived 400 years old. this place contain haft of the animal and plant species of the planet
beside the look about what we have on earth, we have given the chance to see how the earth is being affected on some parts of the world:
-forests in Tasmania depleted in the last 200 years.
-Helicopter trying to put out forest fires
+meant for industrial logging zone
+create a plantation of eucalyptus trees because it is profitable
-reduction of biodiversity
+most efficient way is to poison the animals living in the habitat with nazi-created poisons.
-deforestation for logging purposes
-animals with lost habitat ( such as monkeys) need to be reintroduced back to the environment
-lost their ability to climb trees
-poachers selling exotic and protected species as pets
-local explained their actions as due to unemployment rates(90%)in the region
-paradox of deforestation
-agriculture lands reduces biodiversity and depriving the indigenous people of their homes
-colonists (farmer) killed by Indians (locals)
-land is ‘given’ to non-indigenous people who do not know how to protect it.
-need to enter a new contract with the environment
-“preserving the land,preserving the monkeys, means preserving”
Cense ranch in Montana
-allying tradition and technology
-open ranch
-cows and calves fed on grass, move everyday to new pastures for feeding so land is allowed to regenerates.( not ‘economical’ in today’s sense).
-gave up haying and other equipment
-borrow or get help from neighbours
-reduce the use of fertilizers by half
-do not use herbicides, do not use growth hormones
-use internet to market products
how to reduce poverty and reduce pressure on the environment at the same time:
in china,10M of cultivated land turns into deserts( world or china?),china’s desert advances 25km per year and on the threshold of Beijing.Area being studied- 1 or 2 sandstorms a year 50 years ago, now 30 or more sandstorms every spring.this leads to resettlement of people( ecological refugees)project to reduce advancement of deserts – plan 5 trees a year by each Chinese.Trees fix dust to ground, moderate humidity, acts as natural barrier,Lack of water and soil limits the success
in US,US-largest exporters of farm products in the world( exports 60% of world’s supply of corn),selective variety of corn chosen, use of pesticides and fertilizers( pollute environment).ecological system weakened from the reduced biodiversity.“formatting nature means managing nature on a short-term basis”.sao Joachim valley California – thousands of trees but ecosystems is dead, no other plants, animals or insects – does not even solve world hunger.800m people are starving, but corn produced used to feed animals.enough to feed the world, but agricultural products are sold to the highest bidder.
Fossil fuel:
-13B litres of oil consumed everyday – coming to end of oil’s abudance-takes millions of years to form,half of known reserves consumed
-40% of energy consumptions come from crude oil
-next element is nuclear energy – ‘it is the reality’
