A $25 million donation has launched the largest coral restoration project in Hawaii, aimed at renewing 120 miles of coral reef along the state's coastline. The project is being spearheaded by the University of Hawaii at Manoa's Hawaii Institute of Marine Biology, in partnership with the state's Department of Land and Natural Resources.

The funding comes from the Paul G. Allen Family Foundation, which aims to support efforts to protect and restore the world's oceans. The donation will be used to deploy teams of scientists, divers and volunteers to restore coral reefs that have been damaged by climate change, overfishing, and other human activities.

The project will focus on collecting and rearing coral fragments in nurseries, and then transplanting them onto the damaged reefs. The team will also use cutting-edge genetic techniques to breed coral that is more resistant to the effects of climate change.

The restoration project is expected to take several years, with the ultimate goal of restoring the coral reefs to their former health and abundance. Scientists hope that the renewed reefs will provide habitat for a wide variety of marine life, as well as protecting Hawaii's coastline from storms and erosion.

This project is a significant step towards protecting and restoring the world's coral reefs, which are under threat from climate change and other human activities. The success of this project could serve as a model for other coral restoration efforts around the world.
