Greta Thunberg, a 19-year-old Swedish environmental activist, has been called “probably the most inspiring speaker of this era” by festival organizer Emily Eavis at Glastonbury, reports the Guardian.

Thunberg took to the Pyramid Stage at the British music festival Saturday to deliver a 10-minute speech on the dangers of climate change.

“The biosphere is not just changing, it is destabilizing, it is breaking down,” she said.

“It will only get worse unless we stop the continued destruction of our life-support systems. unless we prioritize people and the planet over profit and greed.” She also took aim at what she called “greenwashing” by world leaders, noting that society has come to “expect” them to lie, reports the Independent.

“We should be fighting for the well-being of people and the environment, but instead we are up against those who are determined to obliterate both,” she said.

“Our political leaders are free to say one thing today and act completely otherwise,” she continued.

“As new coal mines, oil fields, and pipelines are opened, they can claim that a climate emergency exists.” But “we can still avoid the worse consequences” of climate change, she added, per the Independent.

“Together we can do the seemingly impossible,” she said.

“After I say local weather, you say justice!”
