We must care for all crew on spaceship Earth.
Animal populations across the world shrunk by an average of 69% between 1970 and 2018, researchers found. The steep loss in biodiversity is caused mainly by human activity — and experts say we have limited time to fix it. https://t.co/9hZjjuDTTT

This storm is HUGE! That’s the Mississippi River and New Orleans on the left. It covers the entire Florida peninsula! We could see through the eye just as it was making landfall. Praying for the safety of everyone dealing with #HurricaneIan. 🙏
