Leopard seals are the only seals that prey on other seal species although fur seals have rarely been on the menu before. These leopard seals should be living in sea ice, hunting other ice-dwelling seals but they have switched to a new food source.

For the Blackfeet Tribe, bringing back buffalo will revitalize the landscape, making it more resistant to climate change.

The ground is made up of both ice and frozen soil called permafrost. As the permafrost thaws, the ground sinks and floods. The ice traps gases bubbling up from the decomposing permafrost. Methane traps 30 times more heat in the atmosphere than C02. As the world gets hotter, the permafrost melts faster – releasing ever-greater quantities of this dangerous greenhouse gas.
