The Science Show

Old satellites and bits of space junk regularly fall back to Earth, burning up as they pass through the atmosphere.
All this burning metal causes a chain reaction and ultimately destroys ozone molecules, which keep us safe from most of the Sun's harmful UVB rays. Could a new era of satellite "megaconstellations", like the one run by SpaceX's internet company Starlink, undo humanity's hard work repairing the ozone layer?
‌Jonathan Webb launches into this issue with Dr Alice Gorman (AKA Dr Space Junk), taking stock of just how many satellites are burning up and what can be done to solve the problem.

A deadly variant of H5N1 avian influenza has finally reached mainland Australia: the last continent without it. Although the risk to human health remains low, this virus has spread through many different species overseas — and not just birds. So are our animals vulnerable? Jonathan Webb speaks with Dr Tiggy Grillo about which animals could be at risk, and what is being done to protect them.

If insects feel pain, do they deserve animal rights as apply to mammals?

The largest, deepest and oldest whale graveyard has been found off the coast of Western Australia: teeming with life. 
Jonathan Webb takes a deep dive with environment reporter, Peter de Kruijff, into the science behind whale falls and their importance to underwater ecosystems.
