Last Saturday was Moving Planet day, an international day of action in support of renewable energy. Events were held in 175 countries. Here in Melbourne people got together to make a human sign of someone riding a bike. I am sitting near the knee.
The event was coordinated by 350.org a group dedicated to spreading the word about the need to reduce greenhouse gas emissions. The 350 refers to the goal of 350 parts per million of greenhouse gases in our atmosphere, which scientists consider to be the safe limit. It is currently around 390 ppm, and increasing. If we don’t start reducing emissions now, we will get to a point where irreversible climate crisis will occur. You can read more about the science behind this here.
