BBC’s Ros Atkins studies Bitcoin’s impact on the environment after Tesla stopped buying vehicles with Bitcoin due to concerns about climate change.

According to CEO Elon Musk’s tweet, Bitcoin fell more than 10% after the tweet, while Tesla shares also fell.

Tesla’s March announcement that it would accept the cryptocurrency met with an outcry from some environmentalists and investors.

The electric car maker announced in February that it had bought $ 1.5 billion (£ 1 billion) of the world’s largest digital currency.
