explanation[1]="In 2007, National Public Lands Day volunteers planted 55,000 trees.  This year, the goal is to plant one million trees!  Not only do trees make our landscape more beautiful, but they also provide shade and places for wild animals to live.  Trees can help clean our air and absorb water during rain storms. Fall is a good time to plant trees in many parts of the U.S. Ask an adult to help you choose and plant a tree in your yard or neighborhood.  And, check out the Activities page to learn how you and your family can volunteer for National Public Lands Day where you live."
explanation[2]="Some birds spend their summers at very northern part of Canada, and fly all the way to the southern tip of South America for winter – about 10,000 miles away!  Of course, not all birds fly that far.  Some fly as little as 300 miles to reach their winter destination.  Fall is great time to head outside and look for interesting birds passing through your area.  Your family might also want to add a bird feeder or bird bath in your backyard.  Birds get very hungry and thirsty on their journey!  Check out the Activities page to listen to bird calls and learn how to identify different types of birds."
explanation[3]="Volunteers collected more than six million pounds of trash.  Together, people in 76 countries picked up trash along 33,000 miles of shoreline – you would have to walk across the United States more than 11 times to cover that much distance!  The most common trash items volunteers found were cigarettes, food wrappers and containers, bottle caps and lids, and plastic bags.  You can help keep our shorelines clean by making sure you always throw trash away in the trash can.  You can also volunteer with your family or school to help clean up trash at your local river, lake, or ocean beach.  Check out the Activities page for volunteer ideas!"
explanation[4]="It is important to be prepared when you head outside for a hike. Check the weather forecast and always hike with an adult. Take along extra food, water, and a first aid kit to help you stay safe. Check out the Activities page to learn about other important items you should bring with you on a hike."
explanation[5]="Trees that lose their leaves in the fall, such as maple, are called deciduous trees.  The tender leaves of deciduous trees will freeze and die during cold winter temperatures, so they shed from the tree in fall.  Evergreen trees, such as pine and holly, do not lose their leaves.  Evergreen trees have a waxy coating on their leaves that protects them from freezing temperatures during winter. Check out the Activities page to learn how to identify trees in your neighborhood."
