'This is war': actor Yael Stone gives up US green card and will now live in Australia to fight climate change

Orange is the New Black star says the air travel needed for a life in two continents is 'environmentally unjust'

The Australian actor Yael Stone has vowed to give up her green card, which allows her to work in the United States, as a "personal sacrifice" aimed at reducing carbon emissions in what she called the "climate war".

In a video posted to Twitter on Tuesday and Instagram on Sunday, the actor and star of Netflix's Orange is the New Black said she came to the decision to give up her green card "after a long, considered process".
