Leonardo DiCaprio has spoken out against President Trump's decision to pull out of the Paris Climate Agreement. The actor – who is well known to be an environmental activist – took to his Facebook page to fight back.

"Today, the future livability of our planet was threatened by President Trump's careless decision to withdraw the United States from the Paris Agreement," he said. "Our future on this planet is now more at risk than ever before."

The actor went on to explain that we need to fight back through "grassroots political action" and gave a list of organisations that can be supported.

"For Americans and those in the world community looking for strong leadership on climate issues, this action is deeply discouraging," he continued. "Now, more than ever, we must be determined to solve climate change, and to challenge those leaders who do not believe in scientific facts or empirical truths. It is time for all of us to stand up, organize, fight back, and channel our energy into grassroots political action."
