A ChangeMaker
A person who talks about saving the planet and making life better for everyone, but never actually does anything. They just like to post about it online and complain about how hard it is to be a good person.
My neighbor said she’s going to save the planet, but she still uses plastic straws.
He posted about saving the environment but still drives a gas-guzzling car.
She said she’s going to live sustainably, but she still buys new clothes every week.
