Enough for everyone

Given the current climate emergency and the broader ecological breakdown that looms, there are few issues more pressing than that expressed by the single word: enough. Yet, it is possible to satisfy humanity’s universal needs fairly—and keep the world livable.

Reversing warming quickly could prevent worst climate change effects: Study

Simple mathematical models suggest overshooting Paris climate accord emission targets for a short time won’t immediately trigger some environmental tipping points, allowing time to act.

Food systems drive a third of greenhouse gas emissions, study estimates

Experts say that reform is needed to make food systems more sustainable, and to function within the Earth's planetary boundaries.

Death by 1,000 cuts: Are major insect losses imperiling life on Earth?

Precipitous insect declines are being escalated by humanity as soaring population and advanced technology push us ever closer to overshooting several critical planetary boundaries including biodiversity, climate change, nitrification, and pollution.

For sustainable business, ‘planetary boundaries’ define the new rules

How does a business grow and expand, but function in a way that doesn't overexploit the Earth? A new enterprise is offering an answer to this question.

Planetary health explores how human-caused perturbations of natural systems influence human health.


Analysis: Pessimism on the food front

Virtually all trends, biophysical and socioeconomic, suggest that levels of hunger, already high, will only increase as the human population grows and its life-support systems are degraded. Steps that might ameliorate the situation are, unhappily, nowhere in sight.
