Petro has implemented some limited pro-cycling policies, but under his watch the number of private cars - and particularly motorcycles - has boomed.

However, car ownership is growing fast, the country is losing it forests at a dramatic rate and it's a significant and growing exporter of hydrocarbons, particularly coal, the dirtiest fossil fuel. And Colombia recently approved the use of fracking, meaning it hopes to accelerate still more its fossil fuel production.
As in Colombia, climate change gases are booming across the developing world. According to a report released today, the planet set a new record in greenhouse gas emissions, driven particularly by China and the United States.
Consciousness-raising marches may be a good first step. But it'll take real lifestyle changes for the planet's wealthy if we want to halt climate change before it becomes too late.
