2,300 endangered species: Controversial de-extinction company Colossal Biosciences joins U.S. effort to preserve their DNA

The Trump administration and a company that is promising to bring long-gone animals back from extinction announced a partnership on [June 25, 2026] to preserve cells, tissue and DNA from threatened and endangered species.

The company, Colossal Biosciences, said its goal was to store samples from every animal and plant protected under the Endangered Species Act, which includes more than 2,300 listings worldwide.

As more species face the risk of extinction, scientists see such biobanks as a critical backup. But concerns are also growing that the rise of genetic engineering and efforts to revive extinct species will erode support for on-the-ground conservation, which often requires protecting habitat from drilling, mining and other development.

The announcement comes as the Trump administration has been rolling back protections on land and water, including through actions to weaken the Endangered Species Act, in favor of expanded oil and gas exploration, commercial fishing and other economic activities.
