Hopefully by now you have heard about 350.org‘s efforts around the world this weekend and are planning to join an action to draw attention to climate change. As of today there are over 4,000 events planned in 170 countries.The reason for the group’s name? Scientists say that 350 parts per million CO2 in the atmosphere is the safe limit for humanity. Many believe it needs to be even lower. Regardless, we are currently at 387 ppm and we need to move faster on lowering that number.

Join an activity where you live (or start one) and take action this weekend!
