What is deforestation? a. Once there were many trees in which many diverse animals lived. However, now there is a growing environment problem called, deforestation. Deforestation is the clearing of forests through cutting or burning them. Deforestation has many impacts not just on the environment but also on humans and the economy. It has been a growing problem for many years now and thanks to that we are losing many of our animals that live in the trees. But, there are ways in which we can stop deforestation, however there is no quick fix. b. FACT- more than 50 %of tree cover has disappeared thanks to us
What are the causes of deforestation? a. need of agricultural land- a. construction uses- trees are used as lumber and land must be cleared make building materials away in order for the to be made into sources crops to grow, and most of food- trees are cut of the time the trees are down and are turned into in the way b. creation of urban areas-in firewood or turned to charcoal which then we order for buildings, can use to heat a house stores, homes, highways, etc. to be built b. made into productsthe trees that covered the furniture and most importantly paper land must be cleared products etc.
Effect on the environment a. destories habitats of a. contributes to global animals, and kills animals warming b. kills trees, our main b. will cause deplition of the source of oxygen water table, the main c. doesn't allow trees to soucre of water for grow back, the rate at people living around which humans are cutting forest areas down trees are faster then the rate at which the forest is growing d. change in climate of the surrounding area
How does this effect the human health? a. the main way that it effects our health is by decreasing our oxygen levels (since trees produce oxygen for us to breath and when they are cut down carbon dioxide builds up with the oxygen decreasing) b. with no oxygen we can not go through respiration(the processes that gives us energy) a. cutting down trees decreases the amount of supplies we need to manufacture medical products and other products as well b. since some animals eat leaves from trees and we eat the animals we can have a decrease in food supply
How does this affect our economy? a. deforestation gives us agricultural land but some forest land does not have fertile soil • the slash and burn method as a way of getting nutrient into the soil but that will only last a few years. and due to this method it will take even longer for the trees to grow back. a. our economy is driven by deforestation since almost all the producuts come form trees • the lumber industy also profits from deforestion but wood cannot be renewed • the government also funds deforestation

Deforestation and its impact on ecosystems a. since many diverse animals live in trees cutting them down will force them to leave b. the animals may not be adapted to other areas so they can die out in other ecosystems c. can have an impact on predator and prey relationships a. increased competition between animals b. complications in food webs c. lost of habitats
How can we adress the issue of deforestation? • We can help by planting more trees. • Reduce reuse recycle. You can reduce reuse and recycle paper products so that there is a less demand for timber, leading to reduced amount of trees being cut down. • Help reduce pollution. Acid rain from pollution contributes to deforestation. • One very important thing we should do is inform others about the epidemic so they can help or spread the word to other people. The more people are informed the better.
