see the stromatolites at Shark Bay

but they’re only found in Western Australia and the Bahamas. If you look closely, you might be able to spot air bubbles where they are breathing. Apparently the air above them is really pure.

Wow this isn’t a very popular goal but I would love to do this… thing is it’s a long way from anywhere, including me. Ah well. Someday perhaps.

They’re living fossils – the same microbes make these as were present at the start of life on Earth. Plus, compared to my megacities goal, this is much more acheivable – I can get to Shark Bay on a long weekend.
