Each increment lost is more critical than the last. The release of more toxic and conventional pollutants to the Columbia River as a result of increased waste streams. Increased pollutant discharges and property damage during flooding. Diminished opportunities to enjoy and use the Columbia River because of pollution from wastewater treatment, stormwater, and other non-point sources. Continued damage to the biological integrity of the ecosystem.
Weakened integrity makes it even more difficult for the system to absorb future impacts.
Impaired quality of life for humans, fish, and wildlife. The issue is how to manage human population growth to protect the integrity of the lower Columbia River and estuary. The effectiveness of land use planning will determine the extent to which sensitive areas and critical habitat can be sustained. Appropriate land use and development practices can reduce the stress placed on the Columbia River's natural systems.
