If environmental reports published this year were connected to an alarm system, the sound inside the United Nation's Manhattan headquarters would be deafening—we are facing a five-alarm fire. Myriad reports warned us we must take immediate action to ensure a sustainable supply of clean food, water and air to a human population projected to rapidly grow to 10 billion, all while stemming a globally catastrophic loss of biodiversity and averting the worst economic impacts of a changing climate.

The news was devastating, but not unexpected. The specificity around the short window of time to act was, however. The world's leading environmental scientists have spoken, and the message is clear: The best time to act was yesterday, so we better start today. The task is much bigger and time is way shorter than previously thought.
