The Great Australian Bight, a pristine wilderness and one of the world's last unexploited areas, is a vital treasure. It hosts thriving coastal communities, whale sanctuaries, and more unique marine life than the Great Barrier Reef.

However, this incredible ecosystem faces severe threats from dangerous and experimental oil drilling and seismic blasting.

It's crucial for all who care about our climate, oceans, and way of life to protect our Southern coastline. Join us in making oil history: act.gp/makeoilhistory

Treaties between tribes and the federal government, particularly concerning resource use and environmental conservation, have long been a source of legal contention. Their exact status and attendant rights generate significant tension, especially regarding state obligations.

Recently, an equally divided Supreme Court affirmed states' duty to manage resources consistent with tribal treaty rights. This ruling impacts states like Washington, which has resisted requirements from the Stevens' treaties, affirming tribal salmon fishing rights. The critical question remains: what additional state obligations ensure resource sustainability, especially amidst climate disruption? Consistent enforcement benefits all, illuminating the state's trust duties to its people.
