International Significance of The Zapovednik System
The anthropogenic impact on the environment - due to pollution, climate change and ultimately human population growth - is generating increasingly serious problems, the solution of which will depend on a better understanding of the biosphere than we already have. To provide conditions in which such an understanding can be developed, it is essential to preserve as far as possible intact examples of natural ecosystems, and the zapovedniks are the only large system of protected areas created primarily for this purpose. In the case of soil erosion, for example, it is only by comparing soil formation and loss rates from intact steppe or prairie and from the same kind of land under intensive agriculture that we can appreciate how destructive of natural capital the latter often is.
Regular long-term monitoring of natural phenomena in zapovedniks has also provided a baseline set of data which is now valuable for assessing how anthropogenic pressure, primarily through climate change, is affecting natural ecosystems. Since the latter perform essential functions such as carbon sequestration and nutrient cycling, it is obviously important to know how these ecosystem services are being affected by anthropogenic pressure. There is an argument for establishing a well funded global network of zapovedniks in order to increase our understanding of anthropogenic pressures on all the natural ecosystems of the world.

Famous quotes containing the words significance and/or system:
“For a parent, it’s hard to recognize the significance of your work when you’re immersed in the mundane details. Few of us, as we run the bath water or spread the peanut butter on the bread, proclaim proudly, “I’m making my contribution to the future of the planet.” But with the exception of global hunger, few jobs in the world of paychecks and promotions compare in significance to the job of parent.”
—Joyce Maynard (20th century)
“Our system of government, in spite of Vietnam, Cambodia, CIA, Watergate, is still the best system of government on earth. And the greatest resource of all are the 215 million Americans who still have within us the strength, the character, the intelligence, the experience, the patriotism, the idealism, the compassion, the sense of brotherhood on which we can rely in the future to restore the greatness to our country.”
—Jimmy Carter (James Earl Carter, Jr.)
