The title 350 comes from 350 parts per million (ppm) of CO2 in the atmosphere, the level scientists say we need to be at if we want to maintain the world as we currently know it. Due to the burning of fossil fuels, we have already reached 400ppm. Unchecked climate change beyond 350 ppm means we’ll see more natural disasters, more disease outbreaks, more food shortages, and a higher sea level rise.
But 350 is more than a number – it’s a symbol of where we need to head as a planet.
To get back down to 350ppm we need to make large-scale changes and think bigger and bolder. We believe that if we can get enough people to care, be inspired, and take action, we can preserve our planet and our future.
