Have you ever been in a place where there were lots of buildings but no trees? New housing developments or parts of a city that have been neglected for a long time may not have the shady spots and fresh air that trees give. As trees breathe, they let out oxygen that humans and animals need to survive. Their roots hold the ground together, making sure the soil doesn't blow away in the wind. When a tree dies naturally in the forest, its wood becomes a home for insects and a cafeteria for the hungry birds who eat those insects. Trees provide so many good things for the Earth.
How can you help the Earth? There are lots of ways to get involved in conservation whether you're a kid, teen, or adult. Check out the local activities, Web sites and library materials listed below for some great ideas.
Growing up with Books and Traveling the World
With a scientist/writer for a mother and a research physician for a father, it’s little wonder that Molly Bang grew up to be a writer and illustrator who would eventually make it her mission to create books that drawn children into the world of science. Her family kept a large library and would often give each other books illustrated by the famous Charles Rackham as gifts. Molly found these to be inspiring.
After she graduated from Wellesley College with a degree in French, Molly traveled to Japan to teach English at a university there for 18 months before returning to work on master’s degrees in Oriental studies. Then it was back overseas to illustrate health manuals for UNICEF, as well as Johns Hopkins and Harvard, working, among other places, in Calcutta and Bangladesh.
Whether it's filled with mossy rocks and ferns or sands and cactus, a terrarium is an amazingly fun way to learn more about nature. With a terrarium in your room, something of the outdoors can always be inside.
Terrariums that feature plants (not animals!) lock water inside to keep the soil moist. When the plants transpire, they let out water vapor. When the soil gets warm, it lets out water vapor. All this vapor collects against the top and falls back as rain.
Our rivers, lakes, and beaches are beautiful, but are they safe? Every day, the toxic runoff from parking lots, busy roads and quiet subdivisions makes its way into our streams and oceans. Even the oil burning off from cars on the roads gets washed into the groundwater and streams by way of the storm drain every time it rains.
The more houses we build, the more pollution we will add to our environment. Every time we lay down a new parking lot or piece of roadway, there is an impact on our environment.
One fine morning, the old wooden dam went up in clouds of smoke and broken timber. It was a huge thing—ancient and strong, built to tame the Rappahannock River. Once the power of the water pushing against it had provided electricity for the town. But that was years ago. The dam was falling apart, but so slowly that it was becoming dangerous. So the Army Corps of Engineers blew it up one morning.
On Thursday, March 18, 2010, Mark Hamilton Lytle of Bard College and author of The Gentle Subversive: Rachel Carson, Silent Spring, and the Rise of the Environmental Movement, will give a talk on the scientist. The lecture, part of the University's Great Lives series, is free and open to the public.
The GBBC is an annual, four-day event that takes a snapshot of where the birds are across the continent. It's an easy, fun, and free way to help the birds. Anyone can do this for as long or as little a time as he pleases, and their Web site has good information on how to get started, .
