What is Sustainability
By: Mike Breton
In ecology, sustainability is how biological systems remain diverse and productive.
Long-lived and healthy wetlands and forests are examples of sustainable biological systems. In more general terms, sustainability is the endurance of systems and processes. The organizing principle for sustainability is sustainable development, which includes the four interconnected domains: ecology, economics, politics and culture. Sustainability science is the study of sustainable development and environmental science.
Water and Sanitation
The Millennium Ecosystem Assessment released in March 2005 concludes that there has been a substantial and largely irreversible loss in the diversity of life on Earth due to human action. Among the outstanding problems are the dire state of many of the world's fish stocks, the vulnerability of the 2 billion people living in dry regions to the loss of ecosystem services and the growing threat to ecosystems from climate change and nutrient pollution.
