Plastiki sets sail: will it help change our approach to waste?

Named in honour of Thor Heyerdahl’s Kon-Tiki raft, which sailed across the Pacific in 1947 (http://en.wikipedia.org/wiki/Kon-Tiki), Plastiki is made mostly from recycled plastic bottles and aims to highlight the damage that non-recycled plastic waste does to the marine environment. In the USa ~38 billion plastic bottles are thrown away each year. The expedition seeks to encourage us to recycle more. You can find out more about their expedition here: http://news.bbc.co.uk/1/hi/technology/8540299.stm & here: http://www.theplastiki.com/.

Plastics in the Pacific Ocean end up as tiny pellets which are floating in a huge mat about 5 times the size of the UK. You can find out more about the dangers of plastic pollution here: https://dlgb.wordpress.com/2008/03/27/how-dangerous-is-plastic-pollution-in-our-seas/

Here are a couple of examples of the allegations that have been made:

What is the future for Portugal’s cork forests?

Corks have been familiar in wine bottles for centuries. The forests that supply them are a rich ecosystem in their own right, but they are under threat as vintners move to using cheaper, more reliable plastic corks. The consequenses for the special ecosystems of the cork forests are serious:
