People's Climate March: Hundreds of thousands march in rallies calling for action on climate change
Organisers estimated that some 310,000 people, including United Nations Secretary-General Ban Ki-moon, former US Vice President Al Gore, actor Leonardo DiCaprio and elected officials from the United States and abroad joined the People's Climate March, ahead of Tuesday's United Nations hosted summit in the city to discuss reducing carbon emissions that threaten the environment.
Current world population: 7.2 billion (figures rounded to nearest 100,000,000)
Number marching: 310,000
Number that found something better to do:7.2 billion (figures rounded to nearest 100,000,000)
Percent: 99.9957% (thanks Craig Mc!)
Perhaps the headline ABC should have run: 99.9957% of world's population didn't march for action on climate change.
