Greta Thunberg is a 16-year-old environmental activist from Sweden, and she had a powerful message for world leaders at the United Nations Climate Action Summit in New York City on Sept. 23. 

The fiery and impassioned speech tugged at heartstrings and hopefully opened the eyes of politicians who have ignored the environmental crisis for too long. However, one politician made sarcastic remarks as opposed to offering support against climate change. 

President Donald Trump seemingly mocked the teenage advocate on Twitter, but she had the perfect response. 

"You have stolen my dreams and my childhood with your empty words." 

With tears in her eyes, Thunberg savagely called out the world leaders at the United Nations Climate Action Summit for destroying the environment and leaving it up to future generations to clean up the mess. Thunberg warned the politicians that she and her peers would be watching them to see if they make active changes to work for a better future. "'Right here, right now is where we draw the line. The world is waking up. And change is coming, whether you like it or not,'" Thunberg said. 

Unfortunately, her speech wasn't taken seriously by one important world leader. 

President Trump proved exactly who he is once again by seemingly making fun of the young activist as opposed to lifting her up and addressing her legitimate concerns. "She seems like a very happy young girl looking forward to a bright and wonderful future. So nice to see!" the president tweeted. The tweet was clearly meant to mock the activist's emotional response and teary-eyed plea for a better future. 

But Thunberg knew exactly where to hit the president where it hurt. 

Thunberg updated her Twitter bio to reclaim the sarcastic insult. The 16-year-old has already accomplished more in her young life than most ever will, plus she is actively trying to make the world a better place. The Swedish teen should be proud of herself, and won't let rude comments get her down no matter who they come from. 

Thunberg and 15 other young people have officially filed a complaint with the United Nations against the five nations with the highest level of carbon emissions. 

"Today at 11:30, I and 15 other children from around the world filed a legal complaint against 5 nations over the climate crisis through the UN Convention on the Rights of the Child. These 5 nations are the largest emitters that have ratified the convention," Thunberg wrote. 

Essentially, the children's complaint is that five countries, Germany, France, Brazil, Argentina, and Turkey, have violated human rights for not taking action against climate change. 

The complaint was filed shortly after the UN's Climate Action summit in which Thunberg gave her emotional speech.
