AQA Geography: Living World
A Consumer - ANS-An organism that gets its energy from eating other organisms; eating
producers or other consumers.
\A Decomposer - ANS-An organism that gets its energy by breaking down dead material like
dead producers or consumers e.g bacteria or fungi.
\A Producer - ANS-An organism that uses sunlight energy to produce food.
\Economic and Political Impacts of Deforestation in the Amazon - ANS-Logging, farming,
and mining create jobs, benefiting the economy and allowing them to improve infrastructure,
healthcare, housing, and make Brazil richer. In fact, the exploitation of the Amazon rainforest
has made Brazil the 5th richest country in the world.
This puts the government in a difficult position as deforestation earns foreign exchange from
selling such materials as gold and wood to other countries, turning it into their main source of
income, but there has been rising pressure from foreign governments and Amerindian tribes,
to stop deforestation.
\Ecosystems - ANS-An ecosystem is a unit of all living, and non-living parts in an area.
These parts are classed as producers, consumers, or decomposers.
\Ecotourism - ANS-Tourism that doesn't harm the environment and benefits the local people
by providing them with a source of income, by acting as guides, providing accommodation
and transport. This means that local people don't have to log or farm to make money,
meaning that fewer trees are cut down, leaving more trees for the future. Ecotourism should
also cause as little harm as possible to the environment by making sure that waste and litter
are disposed of properly. This helps sustainable development by improving the quality of life
for local people without stopping people in the future getting what they need.
\Educating about Rainforest - ANS-Some locals don't know about the environmental impacts
so they try to make money to overcome their poverty. Educating these people about the
impacts and ways to reduce them decreases their effect on the environment. Educating
them on other ways to make money without damaging the environment would decrease their
impact. This means that the rainforest can be conserved for future generations. Educating
the international community about the impacts would also reduce demand for products that
lead to deforestation and put pressure onto governments to reduce deforestation.
\Environmental Impacts of Deforestation in the Amazon - ANS-Trees remove CO2 from the
atmosphere when they photosynthesize, and without trees, less CO2 is removed. The
Amazon holds around 100 billion tonnes of carbon and the burning and deforestation of
trees will release some of this as CO2 which adds to global warming.
Without, trees water isn't removed from the soil and evaporated, resulting in fewer clouds
being formed and reduced rainfall; having a massive impact on the climate of the forest.
Without a canopy to intercept the rainfall and no roots to absorb and hold the soil together,
the heavy rain washes the soil away, and leeches it's nutrients. Because of this, plants won't
be getting many nutrients and if the soil is washed into rivers, it can kill fish and raise the
level of the waterbed, causing flooding.
Without a canopy, there will be no leaf fall to give nutrients to the soil, making the soil
infertile.
Fewer trees means fewer habitats and food sources for animals and birds, reducing
biodiversity as animals move or become extinct.
