This video was made in collaboration with BBC Earth in partnership with BBC Studios. Head over to https://youtu.be/0ErXkeWJdS0?si=ybYPqc3nQ_u1esfQ to find out more! Save our Species explores the incredible (and unexpected!) tech-based approaches being tested to help protect wildlife, including drones that catch whale snot, ferret vaccines shot from ATVs and even cryogenically frozen DNA.

That cannon that shoots salmon across dams is more than just a meme. It's a real way scientists are trying to help fish return from their breeding grounds... and it's not even the silliest one.
