There are only about 1.6 billion cars in the world. Only about 20% of the world population has access to a personal car. Less than that have ever ridden a plane, and less than 10% fly with any regularity.

A super majority of greenhouse gases emitted are due to the lives of the top 20-30% of the population (of which unfortunately I am a part). The remaining people's contributions are small. 80:20 rule in full glory.

Worst of all, the 80% are the most impacted by climate change as TFA illustrates.
