Transcript of What would happen if we cut down all the worlds trees?

What can we do?
Fortunately, there are things that every one of us can do! Planting trees is an easy way to help. Ask your parents if you can plant some in your yard or ask your teacher if your class can plant some trees in your schoolyard. It is important that everyone knows about forest issues. Tell your parents what you learned. Maybe you could even talk to your class about it. The more people that know, the more changes we can make!
Filthy air
FILTHY AIR: Without trees, humans would not be able survive because the air would be bad for breathing. If anything, people would have to develop gas masks that filter the little oxygen that would be left in the air. Trees are a crucial part of the carbon cycle, a global process in which carbon dioxide constantly circulates through the atmosphere into organism and back again. Carbon is the second most valuable element to life, you know, after water. Anyway, trees take carbon from the atmosphere through photosynthesis in order to make energy. This carbon is then either transferred into oxygen and released into the air by respiration or is stored inside the trees until they decompose into the soil. Therefore, the absence of trees would result in significantly HIGHER amounts of carbon dioxide in the air and LOWER amounts of oxygen! The filthy air would also be full of airborne particles and pollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide and its temperature may increase by up to 12 F.

The dangers of deforestation
Even if our species survived the end of deforestation, life as we know it would be very different from now in 2015, where only half of the world's forests are gone. Scientists think our great-grandchildren might not even have the chance to visit the great Amazon rainforest in 50 years! Yet on such a dry, lifeless world, no one would be left to experience the consequences of deforestation. The decrease of property value and potential increase of urban noise, compared to other disasters like roadside spills, animal wastes, water runoff into streams, and sewage/farm chemicals left unfiltered.

Trees are like natural air conditioners and water pumps. They cool the earth by giving shade and recycling water. By cooling the air and ground around them, the shade from trees helps cool the earth’s temperature overall. Trees also help moderate the earth’s rainfall, which also helps keep the temperature cooler.
Threats to our forests
Forests are also being destroyed by acid rain resulting from our pollution-causing activities and through the introduction of disease and invasive species. Deforestation is a very real environmental threat. Our once vast forests are disappearing. All around the world, trees are being cut down too quickly for earth to regenerate new forests.

For most of human history, deforestation in the Amazon was primarily the product of maintenance farmers who cut down trees to produce crops for their families and local consumption. But in the later part of the 20th century, that began to change, with an increasing proportion of deforestation driven by factory activities and large-scale farming. By the 2000s more than three-quarters of forest clearing in the Amazon was for cattle-ranching.
Animals/Plants that will go extinct
A harmful downfall to deforestation is some animals can go extinct or lose the homes all because of us.
Plants may also go extinct from deforestation some of the species of animals that can go extinct are the grizzly bear, birds, monkeys, etc all of these animals can go extinct because of us.
Sustainability
