For those who want to reduce the human "footprint" on our planet, is it irresponsible to pursue ever more leisure?

Leisure takes up resources, but resources for what? For fun? If you want to reduce your use of resources on the planet, does that mean you should want to find leisure pursuits that do not involve many resources? Or any resources? Or is the whole concept of leisure a waste? Should we be working all the time for the benefit of each other or the benefit of the planet (future generations)?

For those who don’t have a problem with human use of resources, is leisure a good thing? Why or why not? How else should people spend their time?
