How did the International Whaling Commission’s goals differ between conservationists and preservationists?

The International Whaling Commission (IWC) has faced significant internal tension regarding the management of whaling as its membership shifted from a focus on industry development to global conservation concerns.1

The goals of the two primary factions within the IWC differ fundamentally:

• Conservationists: This group advocates for the sustainable management of whale populations. Their objective is to maintain a regime that allows for the "orderly development" of the whaling industry, provided that the harvest levels are scientifically monitored to ensure the risk to individual stocks is not significantly increased while allowing for the highest continuing yield.1
• Preservationists: This group opposes all forms of commercial whaling based on ethical grounds. Their goal is the protection of whales as a moral imperative, regardless of whether specific populations might technically support a sustainable harvest.1

While conservationists seek to balance human predation with ecological stability, preservationists prioritize the intrinsic right of whales to exist without human interference. These conflicting perspectives have defined the IWC's debates since the implementation of the moratorium on commercial whaling.12
