There are some really good programmes on TV about nature and wildlife - we are very blessed with them. Their quality is incredible.
Here's another - the series is called Equator from the Air. Gordon Buchanan takes an amazing journey round the Equator with experts who are racing to save wildlife and people.
Tonight (9th June 2019, 8pm UK time on BBC2), he croses the Pacific and drops in on the Galapagos Island.
There he discovers huge evidence of human intervention - domesticated pigs have gone wild and decimated the tortoise population. Drones are helping to track these species in danger.
He also joins in to see how a tropical lake may hold clues about how to secure the world's coral reefs.
Do watch - the series has been really good so far and is really sending a message home.
