If you haven’t heard the term “350″ yet, you certainly will soon enough. October 24, 2009 is set to be the International Day of Climate Action. We’ll explain it a bit more below, but this 90 second animation does a great job of summing it up:

The mission of 350.org really explains why “350″:

350.org is an international campaign dedicated to building a movement to unite the world around solutions to the climate crisis–the solutions that science and justice demand.

Our mission is to inspire the world to rise to the challenge of the climate crisis—to create a new sense of urgency and of possibility for our planet.
Our focus is on the number 350–as in parts per million, the level scientists have identified as the safe upper limit for CO2 in our atmosphere. But 350 is more than a number–it’s a symbol of where we need to head as a planet.

To tackle climate change we need to move quickly, and we need to act in unison—and 2009 will be an absolutely crucial year. This December, world leaders will meet in Copenhagen, Denmark to craft a new global treaty on cutting emissions. The problem is, the treaty currently on the table doesn’t meet the severity of the climate crisis—it doesn’t pass the 350 test.

So how do you get involved? Search for activities that are already planned in your community. Here in South Florida where Eco Echo is located, there are dune plantings, 350 Day Festivals, and eco-themed lectures.

You can also help “Build the Buzz” by spreading the word to your family, friends, and neighbors in some creative ways! We like the simple sidewalk chalk idea, and the yummy cookie idea (bake some at a perfect 350 degrees and others that get burned at 450). Visual and tasty!

How will you 350?
