Nature Live Online: Life Under the Ice

Cyanobacteria are a group of organisms on which we all depend.

They helped create the very oxygen vital for so much to surive and flourish and are some of the oldest living things on Earth. They still exist today and can be found thriving in some of the most inhospitable places on the planet including frozen lakes where no other life can be found.

Join host Alastair Hendry with scientist Carla Greco as they reveal more about these incredible organisms.
