World’s largest human migration will kick off soon


China’s ministry of transport says around 700 million people, more than half of China’s population, will make 2.85 billion road, rail, air and ferry trips around the spring festival, as the holiday period is called. Even though extra services are laid on, many travelers have to queue overnight to secure a ticket.

CrashCourse Biology:Photosynthesis


“A great writer reveals the truth even when he or she does not wish to”.TOM BISSELL

Hank explains the extremely complex series of reactions whereby plants feed themselves on sunlight, carbon dioxide and water, and also create some by products we’re pretty fond of as well.

I watched this video…and then, the next day, a girl in my bio mentioned CHEMICALS. IN THE SAME WHINY VOICE AS HANK.

he only reason I’m passing biology is because of crash course. Crash course teaches better than my teacher.

Community Awards from BCLC founder


On April 12, 2011, Stephen Jordan described the four-year-old Siemens Sustainable Community Awards, the importance of public-private partnerships for sustainability, and the rise of the business of sustainability.

 

Throughout the country, local governments, chambers of commerce, economic development authorities, and other organizations have taken tremendous steps to improve quality of life, be a steward of the environment, and increase the ability to sustain a successful community for generations to come. These efforts deserve national recognition. The Siemens Sustainable Community Awards program provides that national platform for recognition and information-sharing.

Demopolis Lock Whirlpools!


Don’t be afraid.

Ajoutée par  le  7 juil. 2011

Video of Demopolis Lock filling it’s chamber with water so a boat can be locked going upstream. These whirlpools are formed on the river that runs near Demopolis, Alabama. These are NOT naturally occurring whirlpools and instead occur because large pipes under the water suck water into the area behind me (not seen in video until I turn to walk off the bridge/platform area, it’s the place to the left) and fill it with water so boats can easily navigate the river without having to load/unload boats onto higher/lower areas all the time.

I wanted to record the entirety of this video because I never knew what a whirlpool looked like when it was forming. Honestly, I think that’s the most interesting part – not the fact that they are A) So big B) TWO of them and C) THEY ARE SPINNING OPPOSITE DIRECTIONS. 😀

This video is meant for educational purposes. Teachers: Go ahead, use it in class. I know I’ve already had a couple of my high school teachers want to show it in class and I gave them the go ahead. I’d prefer if people not to reproduce this video content unless they are making an educational video in which this is being used as an example.

Have fun guys and gals, and I hope that this is a better description than was here before.
