About 50 "Rebel Mothers" gathered in Uppsala on Saturday to demonstrate against climate change. Annie Mattsson, one of the leaders of the group, says: "What does it matter if the earth becomes uninhabitable?" "We are here with our emotions and hope that it opens its eyes to what is happening," says Mattsson.

In the clip above, she tells us more about the demonstration and why it was so important for her to be there. The demonstration was one of about fifty cities around the world where "Rebels" gathered on Saturday.
