Support for Greta Thunberg is evidence of "white supremacy", "white privilege" and "white power", activists claim.
The 16-year-old environmental campaigner has gained international visibility for her climate activism, including a fiery speech to world leaders at the United Nations General Assembly where she accused them of stealing her dreams.

However some are questioning however why Greta, a white child, is gaining so much attention over indigenous activists. They say that Greta is benefiting from a "global system of white supremacy" which has given her "privilege and a platform".
"Y'all need to ask yourselves why you find it so much easier to hear from white people, regardless of age, when it comes to the violence they have caused across the world," No White Saviours tweeted.
"It is a SYMPTOM of global white supremacy that certain people are HEARD & given a platform, certain people have access to the RESOURCES to be the HEROES that the world will pay attention to."
"Greta at the UN was the epitome of White Privilege/White power= Save white kids!" another tweeted.
Others point out the work that people of colour have been doing to protect their communities from environmental destruction and say that this is being ignored by the focus on Greta.
"INDIGENOUS PEOPLE HAVE BEEN WARNING EVERYONE ALL OVER THE GLOBE ABOUT "CLIMATE CHANGE" FOR DECADES!!" one person tweeted. "There is no mention of them now that this is mainstream. Just Greta..."
"I'm glad to see so many sharing @GretaThunberg 's #HowDareYou message," another tweeted.
"However, Indigenous peoples have been saying this for 500 years. So it is not a new message. Her message has political and cultural authority due to white supremacy."
White environmentalists are instead urged to support and raise awareness of the work being done by people like Canadian Indigenous teen Autumn Peltier, an advocate for water protection of the Great Lakes, and 'Little Miss Flint', a youth activist raising awareness of the US city of Flint's water crisis.
