Environmental features like oceans, rivers, and wildlife populations do not respect national boundaries. Human activities are radically altering the ecological processes through pollution and the destruction or modification of ecosystems. All nations have to recognize their common interest in the world environment that we all share. We are all members of the same species and have a responsibility towards one another because our actions affect people globally. All life on Earth depends on water.
Wetlands play a vital role in maintaining biodiversity.
They are the breeding ground for many endangered migratory birds. They are also an important fresh water source for many rural communities in South Africa. Yet many wetlands, both in South Africa and here in the United States, are being destroyed or degraded due to drainage programs caused by crop production and timbering. Others are filled in to build roads and houses. The demand for water is increasing daily because of the population explosion and industrialization.
