Not all changes are an improvement, but all improvements are a change. That applies to both our lifestyles, especially in rich countries, and corporations, what they do and how they operate.

Animal agriculture is the most obvious example to me, it's unjusifiable ethically let alone environmentally so no matter what people are gonna have to stop eating animals and their secretions, and most people can stop pretty easily and eat healthily (it's extremely easy to do better than the SAD) so start now and get ahead of the curve
