Mr.Popham helped local indigenous trees to survive by getting rid of the invasives and established this Arboretum of indigenous Dry Zone trees. He gifted the Arboretum to the Institute of Fundamental Studies (IFS) in 1989 before he left Sri Lanka for the UK. The IFS called for managers in 2005 and Ruk Rakaganno took over the management of the Arboretum.

It is necessary to keep our beaches clean if we hope to keep our oceans clean. Beaches are home to various creatures. When the tides rise, it collects items on the beach and takes these out to the sea, It later goes to the oceans and gets eaten by the marine life. 100 million marine mammals each year are said to be suffering from plastics and rubbish sent by us to the ocean, The beaches bordering Colombo are getting dirtier and dirtier as people throw their plastic and broken glass bottles and candy wrappings on to the beach. Even personal domestic waste is sometimes found on the beach.

The Women's Environment Center was set up in 1992 in order to focus on women's environmental problems, particularly in the rural areas, and to involve women in the struggle for a better environment. These women have to find their own sources of water, firewood and food. The destruction of forests depletes the water and fuel sources, supplementary foods and local medicines which they collect from forest sources. This destruction of the environment affects them a great deal, as it is the woman's role to find these resources.
