The United States, UK, Japan, and Russia sign the North Pacific Fur Seal Convention of 1911 banning open-water seal hunting, the first international treaty to address wildlife preservation issues.

The North Pacific Fur Seal Convention of 1911, formally known as the Convention between the United States and Other Powers Providing for the Preservation and Protection of Fur Seals, was a treaty signed on July 7, 1911, designed to manage the commercial harvest of fur-bearing mammals in the Pribilof Islands of the Bering Sea. The treaty, signed by the United States, Great Britain, Japan, and Russia, outlawed open-water seal hunting and acknowledged the United States' jurisdiction in managing the on-shore hunting of seals for commercial purposes. It was the first international treaty to address wildlife preservation issues.
