“Some of the oldest organisms on Earth are cyanobacteria: they have a fossil record dating back 3,500 million years. These photosynthesizing life forms have experienced extreme environmental events — from very cold periods to atmospheric pollution to mass extinctions. By studying their resilient nature, we can find solutions for how to adapt to the climate changes we’re experiencing now.
