A Republican congressman tried to minimise Greta Thunberg's argument with a flawed analogy at yesterday's climate change hearing – and ended up getting completely destroyed by the teenage activist.

Representative Garret Graves from Louisiana asked:

If you were sailing across the ocean and you’re picking up trash along the way, and for every one piece of trash that you pick up there is a boat right next to you dumping out five pieces. How would that make you feel?

His point was presumably to try and suggest that the US's environmental responsibility is minimised by other countries' actions, but Thunberg was having none of it, pointing out that according to his analogy, they were all doing damage, and it doesn't cancel itself out.

If you use that logic, then I am also dumping a lot of trash in the ocean. And then I would stop dumping my trash in the ocean and tell the other boat to stop dumping their trash in the ocean as well.
