"If burning fossil fuels was so bad that it threatened our very existence, how could we just continue like before? Why were there no restrictions? Why wasn't it made illegal?"

These are heavy questions for a 16-year-old. But Greta Thunberg isn't your average teenager.

We first introduced you to Thunberg when she was getting ready to set sail across the Atlantic from Europe to attend a United Nations Summit on global warming. Thunberg didn't want to contribute to the heavy greenhouse gas emissions that planes release into the atmosphere, so she made the trip on a 60-foot, zero emissions racing yacht.

After a two-week journey on the open seas, Thunberg arrived to a New York City marina on Wednesday. She reports that she didn't feel seasick at all on her trip. At a press conference after her arrival, however, she admitted, "The ground is still shaking for me."

Thunberg traveled to the U.S. for the United Nations Climate Actions Summit and she plans to join other climate activists for a protest in front of the United Nations on Friday.

Thunberg's activism has inspired protests and school strikes in her home country of Sweden and around the world, and she has been nominated to receive this year's Nobel Peace Prize.

Along with continuing the fight for climate change awareness, now that she has reached her destination Thunberg says she's looking forward to resting and eating food that isn't freeze-dried.
