June 14: Flag Day
June 14 is National Flag Day in the United States, a day to commemorate the adoption of the Stars and Stripes as our flag.
The idea of a special day honoring our flag has been around at least since 1885, when schoolteacher Bernard J. Cigrand held the first celebration of the flag's 108th birthday at Stony Hill School in Wisconsin. Over the years, Mr. Cigrand became an advocate for the recognition of Flag Day, later becoming the president of the American Flag Day Association.
However, it wasn't until 1916 that June 14 was officially proclaimed as Flag Day by President Woodrow Wilson. National Flag Day was later established by an Act of Congress in August, 1949.
On the week of June 14, the U.S. flag will be displayed on all government buildings, and U.S. citizens are encouraged to display the flag as well.
You can print and color your own Stars and Stripes here.

World Environment Day: Biodiversity
Many Species. One Planet. One Future.
June 5th is World Environment Day (WED), established by the United Nations General Assembly in 1972 as a day to highlight the political, social and economic problems of the global environment.
2010's theme focuses on biodiversity and will start with the Environmental and Conservation Conference in Rwanda. In addition to hosting three days of keynote speeches addressing strategies to restore "forests and freshwaters to mangroves and wetlands" through sustainable development and measures to combat poverty, the Rwandan government has organized a community tree planting involving 10,000 participants.
In North America, the city of Pittsburgh has been chosen to host the United Nations Environment Programme (UNEP). Click here for a list of WED activities for the entire family.
What is biodiversity and why is it important?
What are keystone species?
How does biodiversity affect ME?
Here's an article about medicines from unusual animal sources: http://www.medicinenet.com/script/main/art.asp?articlekey=52324
And an article about pharmaceutical plants: http://www.telegraph.co.uk/gardening/3293327/For-purely-medicinal-purposes.html

What is biodiversity and why is it important?
Biodiversity is the rich variety of life on earth. This includes plants, animals and even the tiniest microorganisms, creatures that can only be seen under a microscope.
Biodiversity is more than just preserving wildlife so that our grandchildren can enjoy gorillas, whales and tigers. The environment is very complex, and even the tiniest creatures play very important roles.
In Hawaii, scientists dangle from steep rock cliffs hundreds of feet off the ground to hand-pollinate a rare plant, the alula (Brighamia insignis). Why? Because in nature, flowering plants are pollinated by birds and insects--this is how plants reproduce and thrive. In the case of the alula, its natural pollinator, possibly a small native moth, has gone extinct.
This means that without the scientists' help, the alula plant will also go extinct (left).
What are keystone species?
Keystone species is a species--plant, animal or otherwise--that is so important to an ecosystem that its removal will have a dramatic effect on the surrounding environment.
The sea otter is an example of a keystone species. Sea otters feed on urchins, which in turn feed on kelp. Without sea otters, urchins are free to reproduce, eating their way through kelp forests and thus destroying vital habitat for fish and shellfish.

How does biodiversity affect ME?
We always hear about how little is known about the rainforest and the potential forest remedies that will be lost with its destruction. What most of us don't know is that many of our life-saving medicines already come from plants and animals found in nature.
Here's a short list of some of the many drugs that have their origin in nature:
- ARA-C, to treat cancer: Caribbean sponge
- Aspirin, used for fever and inflammation: meadowsweet and willow bark
- Calcimar, for osteoporosis: Coho salmon
- Captopril, to lower blood pressure: Brazilian arrowhead viper
- Codeine, a painkiller: poppy
- Digoxin, vital in treating patients with heart failure: woolly foxglove
- Integrelin, to treat heart patients: southeastern pygmy rattlesnake venom
- Lidocaine, an anesthetic frequently used in dentistry: barley
- Quinine, used to treat malaria, and Quinidine, to regulate heart rhythms: Peruvian quinine tree
- Tubocurarine, used as a muscle relaxant in surgery: curare vine, Chondodendron tomentosum
- Vincristine, used to treat cancer: Madagascar periwinkle
- Warfarin, used to prevent blood clots: sweet clover
In fact, scientists are urging the protection of the deadly cone snail, known for killing unwary swimmers, because they hope to find uses for its venom in the treatment of pain, heart disease and spinal cord injury.
