Jeff Merkley, a Democrat senator from Oregon, and other legislators in the Pacific Northwest along with the area’s tribal leaders have requested alterations in the environmental regulations and increased financing to cope with the hazardous pollution of salmon after an inquiry conducted by Oregon Public Broadcasting and ProPublica. Salmon has been a huge part of native culture and is regularly eaten at ceremonies. This has been a problem of concern for both tribal members and scientists for a long time but the government has not done anything to keep an eye on water pollution levels in the Columbia River Basin. The results acquired by ProPublica and Oregon Public Broadcasting of contaminants found in Columbia River Salmon that can harm the health of the 68,000 tribal citizens living in the area, are deeply concerning and must be addressed, according to Senator. Ron Wyden, ein Demokrat aus Oregon.
