earthy
A tree-hugger who thinks granola is a meal, free-range chicken is a lifestyle, and co-ops are the future. They also think you're a menace if you don't live in a van and eat kale for breakfast.
This earthy guy tried to save a tree by yelling at a construction site. No one listened.
She turned down a job at a bank to live in a co-op and eat nothing but quinoa.
He refused to use a plastic bag and got yelled at by a cashier.
