How does infinite economy growth even serve us anymore?

I not only think it is unnecessary, I believe that the constant growth required by a capitalist economy is the root cause of climate change - green ways of energy and recourse production can't keep up with the demand, so dirty recourses like fossil fuels are used.

I'm not saying here that development is unnecessary, I'm saying growth is unnecessary. With growth I specifically mean economic growth and development can exist without growth.
