In the Pacific Northwest, killing sea lions is a necessity
Don’t let their adorable faces and playful personalities fool you: California and Steller sea lions are capable of having disastrous impacts on nonnative ecosystems. In places like the Columbia River Gorge, these so-called dogs of the sea have been encroaching on native fish habitats for decades.
