Sea otters, once nearly extinct due to excessive hunting, have successfully rebounded in British Columbia, playing a crucial role in stabilizing kelp forests by curbing sea urchin overpopulation. However, their increasing numbers have drawn attention to the plight of northern abalone, a critical food source threatened by otter predation. Finding the right balance in conservation strategies is essential to protect both species from growing pressures.

Advocating for biodiversity, E.O. Wilson suggests that dedicating half of Earth to nature is crucial for preventing a sixth mass extinction. In conjunction, M.C. Davis has embarked on an ambitious project to restore the longleaf pine ecosystem in the Southeastern U.S., investing extensively in native species reintroduction and tree planting. His Nokuse Plantation represents a major step toward preserving essential habitats for countless species.

Brazil’s humpback whale population has recovered from about 2,000 to nearly 35,000 after commercial whaling pushed the species close to extinction. Protection measures and a global whaling ban helped the whales return to Brazil’s waters. Scientists are now studying their migration, family links and behaviour, while tracking threats from fishing nets, ships and warming seas.
