Biological diversity has become widely recognized as a critical conservation issue only in the past two decades. The rapid destruction of the tropical rain forests, which are the ecosystems with the highest known species diversity on Earth, has awakened people to the importance and fragility of biological diversity. The high rate of species extinctions in these environments is jolting, but it is important to recognize the significance of biological diversity in all ecosystems. As the human population continues to expand, it will negatively affect one after another of Earth’s ecosystems. In terrestrial ecosystems and in fringe marine ecosystems (such as wetlands), the most common problem is habitat destruction. In most situations, the result is irreversible. Now humans are beginning to destroy marine ecosystems through other types of activities, such as disposal and runoff of poisonous waste; in less than two centuries, by significantly reducing the variety of species on Earth, they have irrevocably redirected the course of evolution.
Certainly, there have been periods in Earth’s history when mass extinctions have occurred. The extinction of the dinosaurs was caused by some physical event, either climatic or cosmic. There have also been less dramatic extinctions, as when natural competition between species reached an extreme conclusion. Only 0.01 percent of the species that have lived on Earth have survived to the present, and it was largely chance that determined which species survived and which died out.
However, nothing has ever equaled the magnitude and speed with which the human species is altering the physical and chemical world and demolishing the environment. In fact, there is wide agreement that it is the rate of change humans are inflicting, even more than the changes themselves, that will lead to biological devastation. Life on Earth has continually been in flux as slow physical and chemical changes have occurred on Earth, but life needs time to adapt-time for migration and genetic adaptation within existing species and time for the proliferation of new genetic material and new species that may be able to survive in new environments.

The United Nations recently outlined the extent of the global water crisis, saying that 2.7 billion people would face severe water shortages by 2025 if consumption continues at current rates. Today, an estimated 1.2 billion people drink unclean water, and about 2.5 billion lack proper toilets or waste disposal systems. More than five million people die each year from diseases related to unclean water. Humans are pumping water out of the ground faster than it can be replenished. In this difficult situation, a water conservationist, Neil MacLeod in South Africa, has found innovative ways to improve his local water situation.
Neil MacLeod took over as head of Durban Metro Water Services in 1992. The situation he found was a catastrophe. Durban had one million people living in the city and another 1.5 million people who lived in poverty just outside it. The entire city was rife with broken water pipes, leaky toilets, and faulty plumbing whereby 42 percent of the region's water was simply being wasted.
MacLeod's crews began repairing and replacing water pipes. They put water meters on residences, replaced eight-liter toilets with four-liter models, and changed wasteful showers and water taps. To ensure that the poor would receive a basic supply of water, MacLeod installed tanks in homes and apartments to provide 190 liters of water a day free to each household. Water consumption in Durban is now less than it was in 1996, even as 800,000 more people have received service. Through sensible water use, Durban's conservation measures paid for themselves within a year. No new reservoirs will be needed in the coming decades, despite the expected addition of about 300,000 inhabitants.
MacLeod has also turned to water recycling. At the water recycling plant, wastewater is turned into clean water in just 12 hours. Most people are unable to discern a difference between the usual city drinking water and the treated wastewater, although it is actually intended for industrial purposes.
Some people still hope that new technology, such as the desalination of seawater, will solve the world's water problems. "But the fact is, water conservation is where the big gains are to be made," says Sandra Postel of the Global Water Policy Project. The dedication and resourcefulness of people like Neil MacLeod offer inspiration for implementing timely and lasting solutions to the world's water concern.
