Our environment is robust and responsive to pressures placed upon it. Some environmental stressors, however, can contribute to long lasting negative effects for both natural processes and human endeavors.
Some stress factors, such as the loss of night sky visibility or impacts on natural sounds, can be mitigated easily. Others - invasive species, chemical contaminants, air and water quality degradation, climate change - are more difficult to control. Scientists must obtain baseline information on environmental resiliency to these stressors in order to develop management programs to deal with their effects.
