Detecting whales, protecting whales
Human activities often have an intrusive effect on nature – whether we build suburbs on formerly forested lands or pollute streams with factory runoff, the things we do affect the world’s other inhabitants. But a small group is looking to mitigate the impact of some human activities on the largest of our neighbors: whales. Noise pollution resulting from maritime activities such as...
