π Brazil's humpback whales making a massive comeback π
Humpback whales are significantly returning to Brazil's coast after facing near extinction from commercial whaling. The population in the South Atlantic has surged from roughly 2,000 to about 35,000 over the last four decades. This recovery is visible near Rio de Janeiro's Guanabara Bay, with whales migrating between June and November. Measures like the 1982 whaling pause and 1987 Brazilian ban were key to this species' rebound. Researchers continue to study these giants, noting new threats from shipping and climate change.
