Global Citizenship – Marine Environment is a maintenance theme that will enable you to discover how your work on the Green-Schools programme has positively influenced environments worldwide while focusing your work on our oceans and seas.

The oceans cover over 70% of Earth123 countries worldwide have a coastline, totalling to 1.6 million kilometres in length. Whether you live on the coast or inland, we all depend on the ocean, the products and services it provides (oxygen production, climate regulation, food etc).

Case studies

We have really enjoyed working on this theme, it has been a real eye opener for all the children and staff, especially considering how topical this is at the moment. We have all realised the importance of protecting the Marine Environment and that even the smallest step can make a difference. We have really been inspired to do whatever we can, and the children, their parents and the wider community are much more aware and perhaps care much more after working on this theme! Even though we don’t live close to a coast, we have come to realise that our actions can have a huge impact on the Marine Environment
