Considering climate change issues overwhelmingly affects ppls from the global south that have been complaining about issues such as cancer valley in Houston, rising sea levels in island nations, indigenous lands that are being seized for industrial farming and cattle, or large scale agriculture that poisons 3rd world countries with pesticides, activist from these areas have overwhelmingly been ignored.

"Thunberg never asked to be the messianic-like face for the climate movement. In fact, she told Congress, “I shouldn’t be up here. I should be back in school on the other side of the ocean.” And by the media and public making her the center of youth-led climate activism, the work of many Indigenous, Black, and Brown youth activists is often erased or obscured."

Edit: honestly the fact that I have to prove that climate change overwhelmingly effects countries that arent even close to primarly white or even white countries that pollute areas that are primarily brown yet the spokesperson is a Nordic white teenager is problematic in itself. The fact that ppl more likely to feel the repercussions of climate change or genocide need a Swede to speak for them is problematic. It basically tells them your voice doesnt matter and you can't speak for yourself
