I recently wrote about the Pacific Northwest’s endangered orca baby boom. Last time I checked, the Puget Sound orca population (off the Washington coast) had welcomed six newborns, with all appearances indicating that more female whales are pregnant. Woohoo! But, not to be too much of a downer, orcas need salmon to thrive. And salmon can’t thrive without free-flowing rivers and good habitat for breeding.
For over 10 years, the federal courts have ordered federal agencies to consider tearing down four dams in particular that are preventing the recovery of the salmon population in this area. These four dams block the lower Snake River. If they were removed, it would be a great help to the endangered salmon.
The really nice HuffPost article linked below tells you everything you need to know about this issue.
