Ia Aanstoot, an 18-year-old Swedish climate activist, is gaining a lot of online attention with her “Dear Greenpeace” campaign, asking the global environmental organization to drop its “old-fashioned and unscientific opposition to nuclear power, and join us in the fight against fossil fuels instead!”

As reported by the Guardian, Aanstoot’s stance is that “Greenpeace is stuck in the past fighting clean, carbon-free nuclear energy while the world is literally burning. We need to be using all the tools available to address climate change, and nuclear is one of them.”
