What is Deforestation?
Soil Erosion
- Soil erosion can be be caused by deforestation which effects the enviorment for the worse
- As you know trees roots are planted in soil and when people come and tear up the trees it eroades the soil and ruin the landscape
-Soil erosion is deadly to the organisms that live in the top soil and and beneth the ground
Deforestation
Water Cycle
Deforestation is the clearing of trees, and transforming a forest into cleared land.
Nearly half of the world’s forests have been cleared, and 32 million acres disappear each year. When they vanish, so do the resources that people need to thrive and so does the habitat that wildlife need to survive.
Where does Deforestation occur?
Causes of Deforestation

Greenpeace

investigates, exposes and confronts environmental abuse by corporations around the world
takes action with its supporters.
campaigns have shifted the buying behavior of major companies, creating immediate impacts in the market and on the ground.
Effects of Deforestation
some countries are chopping down their forests at astonishing rates.
The world's highest rates of deforestation, a significant cause of global warming, are happening in the key emerging economies of Indonesia, Russia, and Brazil, according to new research evaluating the state of the world's forests.

Trees are cut down to make roads and more space for humans as populations increase at record space

As more people move into forested and rural areas the people need more resources
Lots of countries build roads in remote areas to encourage people to settle there and when people do settle there they usually use the method of slashing and burning the forest to make room for farms and pastures
The roads built by countries also attract loggers who cut down as many of the beautiful trees as they can to make money and sell them
Lots of people have been relocated by the government to live in big forests like the Amazon to decrease the population in the cities but the people who settle there cut down most of the trees on their land
What is being shown in these two pictures is a forest before and after urbanization, when humans destroyed the forest to make one of the biggest cities in the world. People did not realize that while they were building a huge city they were destroying one of nature's beautiful cities along the way.
This image is showing just how much of the world is urbanized. Every single continent has cities with a population of over 5 million. With this many people in the world many resources are needed, including wood from tree. There is also very few places in the world that have not been touched by people. Almost every forest on earth has been affected

Endangered Species
If corporations have the ability to destroy the worlds intact forests, then they also have the power to save them.
Species all over the world are endangered because of careless human acts, like deforrestation.
About 10,000 different species go extinct each year.
Species such as, Tigers,Mountain Gorillas, Giant Pandas and Golden Lion Tamarin's are highly endangered, and one of the main reason why they are is because of deforrestation.
Overall Urbanization is a huge threat to forests and is a major cause of deforestation. As humans advance in technology and our population grows larger and larger we keep pressing forward. We build huge cities and even large farms. What we don't see as we are advancing, though, is that we are also hurting the environment, especially forests. Humans rely so much on forests and their trees that we never think about a time when we won't have them, but we don't realize is that time could be coming very soon, and it is our own fault.
By Lizzy, Jenna, Kailey, and Ali
There are many reasons why the most beautiful forests on earth are all disappearing
Logging:
Lots of people are willing to kill so many of these trees to use the tree for its wood and many of its other useful resources
Urbanization:
Whole forests of trees are being cut down to make room for more humans, roads, and even bigger cities
Mining:

Oil and coal mining use a large amount of forest land and the waste from the mining pollutes whatever tree thats been spared from being chopped down
Trees are not the only things that are harmed by deforestation
Global Warming:
Without trees to rid the earths atmosphere of carbon dioxide and other greenhouse gases they are lest in the air and temperature will continue to rise
Endangered Species:
As forests are being cut down animals die from habit loss, there food source, and even the smoke and fire caused when the trees are burned down
Soil Erosion:

Without the trees roots to anchor it in place and no nutrients coming from the tree, soil will turn to sand and blow away
Water Cycle:
Trees store almost all runoff and rain water in them, and without them there could be floods in some places and droughts in others
How to Help
The business of felling or cutting down trees and preparing for timber
Half of the world's most important sites for biodiversity are threatened by commercial logging
The most logging takes place in forests that are rich in biodiversity

Biodiversity
- A variety of life in an ecosystem or a habitat

Trees play a very important role in the water cycle
Trees absorb the rain that falls and stores it in its roots - without the trees the none of the water will have anywhere to be stored so flash floods are an effect of not having those trees
Trees lessen pollution in water by stopping polluted runoff - When there aren't trees to cleanse the water the water becomes dirty and polluted and the water can harm many plants and animals
According to the National Geographic Society, more than half of the water in the Amazon's ecosystem is held within the plants - In large forests like the Amazon there are hundreds of thousands of trees that control the water flow, if there weren't trees to control it there would be major floods that could kill many of the organisms that live there
Trees absorb about 50% of water when it precipitates in its roots and soaks it underground
The trees only let about 10% of the water runoff into nearby bodies of water which helps to control flooding
40% of the water is evaporated into the air
Without the trees only 15% of the rain water is absorbed down into the ground
55% of the water is runoff without the trees roots there to absorb it into the ground which causes major flash floods
With only 30% of the water being evaporated into the atmosphere after some time there can be major droughts and desertification
To make matters worse many loggers illegally cut down trees to make more roads to get to more forests and cut down those trees
Logging operations provide the world's wood and paper products
Climate change is the No. 1 problem caused by deforestation
Climate Change
Greenhouse Gases-
Gas molecules that absorb thermal infrared radiation
Carbon dioxide is the most abundant gas in the earth's atmosphere
Trees help to lessen and control the amount greenhouse gases in the air, especially carbon dioxide, but without the trees to do this job all of the stored carbon and gases are realeased into the atmosphere
From 2000-2005 studies showed that 3 billion tons of carbon dioxide was released into the air but luckily the numbers have started to go down as deforestation decreased, but not by much
In this photo you can see where climate change is at its worst, specifically Brazil, Central America, South and Central Africa, and Australia.
The places where deforestation is the biggest issue is the same places as climate change is an issue. This is showing that climate change is a major effect of deforestation.
Climate change is just one of many effects of deforestation. Trees help to reduce and store the greenhouse gases in the air and without the trees the gases are released into the atmosphere and causes a major change in temperature. There are also many effects of the climate change such as melting ice caps which causes sea levels to rise which can cause flooding, pollution is released into the air, and many plants and animals cannot handle the sudden change in temperature so they die. So, deforestation is a major cause of climate change and can have even more negative effects from that.
As the number of trees on earth decrease, the water cycle gets more and more disrupted. Trees help store more then half the water in forests in its roots, depollutes the water, and help the water evaporate into the atmosphere. Without the trees there will be major flash floods, dirty and polluted water which can poison many organisms and kill them, and after a little while many places will be left as dry and barren deserts. If deforestation does not decrease soon the whole world will be in major danger from the water cycle being disturbed.
what we can do
to help
Plant a tree-
even just planting one tree can make a difference some day after the seeds from that tree grow it can make a forest
Go paperless-
this probably seems like an impossible task but lots of schools are switching to laptops and tablets instead of paper
Recycle and buy recycled products-
you should always recycle paper because it helps save the trees
Using prebuilt buildings rather than building new ones-
Every time a new building is built on new land, more forest is destroyed.


Most logging is illegal under national laws
In lots of area around the world illegal logging is more common than the legal variety
Greenpeace:
Greenpeace investigates, exposes and confronts environmental abuse by corporations around the world

WWF:
WWF has been working to protect forests for more than 50 years.

RAN:
RAN has donated millions, in efforts to secure protection for millions of acres of traditional territory in forests around the world.

Amazon Watch:
amazon watch is working directly with indigenous communities to build local capacity and advance the long-term protection of their lands.

nicodemus wilderness project:
nicodemus wilderness project is a service-learning program
what we can do to help:
plant a tree, go paperless, recycle, and use prebuilt buildings rather than building new ones
This is a chart showing the legal and illegal logging in a state in Brazil. It shows just how much illegal logging has increased. Since 2010 illegal logging has increased to be almost three times more then legal logging. The reason there is a national law on limited logging is to conserve forests and decrease deforestation. If three quarters of the trees cut down for logging was illegal then that means three times the expected amount of trees would be cut down. Trees are being cut down for lumber at a very fast rate and is causing deforestation.
So, logging is one of the major causes of deforestation. Trees are cut down to make paper and wood products both legally and illegally. When trees are cut down legally it has a huge effect on the forests that are being cut down and soon all of the forests in the world could be gone
Deforestation is a global issue that needs to end
Trees are being cut down around the world at astonishing rates.
People are cutting trees down both legaly and illegaly to sell, they're cutting them down to make room for people to live and urbanize, people cut them down to make room to mine and the mining also pollutes the air and kills trees.
When the trees are cut down though it's not just the tree that is affected, other things are effected from it. First, there are major climate changes that can drastically change the temperature and second many animals are killed without the trees to be their habitat.
Third, the water cycle is disrupted and soil erodes. Even though everything may be looking down for forests there are things being done to help. There are multiple organizations that help to conserve the trees but you can help too!

-Gold, dimonds,copper and other precious resorces are in the rain the rain forest
-when people take these resorces from the rain forrest it lead to major destuction of the habitat
-These resources are extracted by big machines (as seen in the picture below) machines that also ruin the soil and habitat for underground animals

Cities are made out of different resources, such as wood and they cut down more of the trees to use to build the city
The actual building of the cities creates lots of pollution and greenhouse gases and it can kill even more of the trees
Cities have cement and the sidewalks in cities are made out of cement so in the summer when it gets really hot the cement heats up and releases greenhouse gases into the air. Since there are cities all over the world that use cement there is a huge amount of greenhouse gases in the air which causes a major rise in temperature and is a cause of global warming
