Commercial whaling causes documented suffering to some of the most cognitively complex animals on Earth, with killing methods that frequently fail to be instantaneous.
Whale welfare in commercial whaling is a profound concern. International Whaling Commission data shows that 20-40% of harpooned whales do not die within seconds, enduring prolonged suffering. Whales live in complex social groups and show grief responses to death of companions. The cognitive complexity, social richness, and demonstrable suffering make commercial whaling one of the most serious animal welfare issues of scale.
