The United Nations Environment Programme announced that the theme of this year's World Environment Day will be small island developing states or "SIDS." Island nations around the world are particularly vulnerable to climate change, natural disasters and rising seas. However, they have also come up with some amazing solutions to cope with these problems.

World Environment Day is June 5, and this year aims to raise awareness about the impact of climate change on small islands states around the world. There's also much to be learned from these countries, which have overcome a number of environmental problems with only limited resources.
