Comments
The Salt Creek Watershed Network (SCWN) set out to organize and motivate
citizens at the watershed level. While preparing their watershed plan, titled
Restoring Balance, they realized that most environmental problems were related
to the negative impacts of humans that resulted in the ecosystem being out of
balance. Thus, all efforts to correct the problems at the watershed level must
focus on finding ways to get things more in balance.
An out-of-balance example provided was how humans have attempted to control
mosquito populations through spraying of chemicals, which adversely affected
amphibians that predate on mosquito larvae. In addition, water quality got so poor
that dragonflies were reproducing less. The loss of the predators led to more
mosquitoes, which led to humans applying more pesticides. If, however, the
ecosystem was allowed to repair itself, more bats, amphibians and dragonflies
would be available to assist in mosquito control. Yet many residents continue to
consider "improved" or enhanced natural areas as simply breeding grounds for
mosquitoes and rats, which also is a problem for watershed restoration.
SCWN found hope in the way the environment restored itself after the glaciers
"destroyed" it down to the bedrock. Nature can heal itself from the negative
impacts of humans. However it is difficult to get municipal officials to understand
the importance of clean water. A recent National Geographic article concluded
that the resource's scarcity is a big reason for officials to be concerned.
Swano identified several economic impacts associated with the degradation of
the environment. One problem is identifying the actual value of the services
provided to humans by the environment. He asked the audience which was more
valuable, a glass of water or a glass of beer. He concluded that the answer
depends on who you ask and what their value system is. It also depends on their
level of education in that highly educated people place a higher value on the
environment. Thus, public education can increase the value of the environment
without making any physical alterations to the environment. Furthermore, it is
difficult to value the services provided by the environment because you can't just
walk into a store and know how much a bat eating thousands of mosquitoes a
night is worth. However, we all know the price per square foot of paving a street.
He then asked the audience which was more valuable, a glass of Salt Creek
water or bottled water. No one would want the glass of Salt Creek water - even
though it was free - but instead would be willing to pay for the bottled water. He
recounted how the water used to be free and early settlers certainly could drink
right from Salt Creek. What has happened in the interim is that pollution has
raised the cost of drinking water from free to what it is today, which is an actual
cost to society. Recent examples of PCB pollution in rivers and the Superfund
program were used to conclude that it is cheaper to keep the environment clean
than it is to dirty it and then clean it up later.
The value of the environmental services that plants provide can be inferred by
making general comparisons with things that we do know the price (or value) of.
For example, if you go out to buy a packet of seeds you know the relative value
associated with the Wolf Road Prairie's ability to generate seeds. Also, if the
deep roots of plants on a streambank are holding the soil in place preventing
erosion, a general comparison can be made with the costs of pouring concrete
along the streambank to prevent erosion. In this case, it is cheaper to let the
plants do it, thereby raising the value of this service provided by the plants.
