Description

Although microbeads from rinse off cosmetics have received a lot of attention lately, the tiny plastics most often being found in our seafood is a different kind of synthetic. We look into marine life in the US and Australia, to find out what plastics escape our household drains and what kind of damage they can do. Also, we always thought Tasmania was different, and now geology can explain why. New discoveries from Tasmania's oldest rocks at Rocky Cape reveal that about 1.5 billion years ago Tasmania was not part of Australia, but wedged between two other continents. The geology of north-western Tasmania may have more to do with North America and Antarctica than it does with the rest of the Australian mainland.
