Essay Notes PROBLEMS/HUMAN INTERVENTION

Two Human impacts- Deforestation and Global Warming

DEFORESTATION. * The state of being clear of trees. * Trees are one of the most important aspects we live in.
Causes
* Urban construction- deforestation for expanding Urban lands. * Agriculture- growing crops, farms for food supply. * Fuels- used as firewood or made into charcoals, being used in heating houses or in cooking.
EFFECTS
* Distribution of Water cycle- trees are one of the important aspects in water cycles, getting rid of trees can disturb the Water cycle. * Flooding and droughts- trees absorb and store a lot of amount of water quickly when heavy rain falls.

GLOBAL WARMING * He gradual increase in the temperature of the earth's atmosphere * Global warming is one of the major problems in this planet.
Causes
* Fossil fuels- humans depend on fossil fuels or gases, which are sources of carbon. * Airplane- airplanes releases large amount of green house gases. * Shippings- we ship a lot of luggage one place to another, which ships use a lot of gases and oil fuels.
Effects
* Polar ice- global warming is when heat is increased a lot, and ice caps are already started to melt. * Diseases- many people will face a lot of incidents or diseases. * Water- water level increasing, island like Maldives can face underwater.

(First Body) First of all Deforestation is the one of the worst problems in human intervention. Deforestation is a state of being clear of trees. Trees are one of the most important aspects we live in. there are many causes and effects because of Deforestation. Few examples of causes are urban construction, agriculture and fuels. In urban constructions, people use trees for making tools such as wooden hammers and people chop down trees to build houses and expend urban lands. In agricultures, peoples or farmers chop down trees to grow crops and expand areas to build a farm for some more food supplies. Fuels are important in this world. However, because of fuels, trees are getting chopped down. They are used as firewood or made into charcoals, also used in cooking or heating houses. We can widen our surface to build buildings or farms, but the risk of getting near the death is getting higher. Chopping down trees can distribute water cycles and can rise the risk of getting flooding or droughts. Trees are one of the important aspects in water cycles, getting ride of trees can cause distribution of the
