Environment
Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth's climate. Global warming is killing many animals all around the world since they cannot adapt so quickly to the earth's increasing temperatures. Global warming is caused by in increase in carbon dioxide levels in our earth's atmosphere. As you probably know,trees do a really good job at moderating these abnormal carbon dioxide levels since they let out oxygen and take in carbon dioxide.
We researched different organizations that help the local environment. We found the organization "Friends of Trees" and with them, we planted trees in Durham city park to help reduce pollution and create a better environment. We planted trees until there was no more room in the park. We did this for 3 hours.

From this experience we learned even more on how important it is to improve our local environment's health and how it affects the community. There were people from all parts of Portland, including volunteers, boy scouts, and even other students.

If you want to help the environment, "Friends of Trees" is a great organization to visit. They are online at http://www.friendsoftrees.org/
Help the trees, save the earth
For this project, we really focused on the environment, especially trees because we realized the importance of a nice and clean environment and how trees play a huge role in controlling global warming
Effects of global warming
The sun gives off solar radiation. Solar radiation heats or earth up during the day. However infrared radiation is released from the earth to cool itself down. The infrared radiation tries to escape the earths surface but some of it is absorbed by greenhouse gases which won't let the heat escape, making our planet warmer. Greenhouse gases are made through human activity which releases CO2.
