Delegates from 196 nations began meeting at a major U.N. summit in Montréal where organizers cast the stakes as a last chance for saving the planet's biodiversity – the variety of life in all of its forms.
The goal of the summit is to get the world back on track toward meeting its obligations in the U.N. Convention on Biological Diversity. More than 10,000 participants are expected; ministers will arrive for talks in the second week.
