Our friends from the fantastic ocean acidification documentary A Sea Change are working on an important new project. It’s called “Shored Up“, and it’s all about sea level rise and the strategies that coastal communities are using to try and keep their beaches.
One issue in particular, beach renourishment, has major environmental implications that aren’t often considered.
