We have been learning many things about water in Unit 2, "Water: Our most important resource", in our textbook Tapestry Reading 1. You can review the things we've learned by reading the blackboard notes that I posted on this blog.
Now Guy Laliberte is on the International Space Station. Last weekend, he presented an incredible webcast from the International Space Station called Poetic Social Mission. The purpose of the webcast was to teach people about the importance of water. The webcast was broadcast from places all over the world including Osaka. Many artists, scientists, and world leaders from all over the world participated in the webcast including former American Vice President Al Gore, David Suzuki, Peter Gabriel, Joss Stone, and Tatsuya Ishii (石井竜也).
Thanks to onedrop.org and the the Poetic Social Mission webcast I have learned many more things about water including:
- 70% of the earth's surface is covered by water
- Most of the water on earth is salt water, which we can't drink
- We need fresh water (淡水). We get most of our fresh water from rivers and lakes.
- Only .007% of the earth's water is contained in rivers and lakes
- 60% of the human body is water
- We have more rain because of global warming
- Many girls in the world cannot go to school because they are busy collecting water
