On the surface yes but until corporations and business are brought to heel, they will simply use up the space you made with your sacrifice. The primary entities responsible for climate change is the private sector, people seeking power and profit without regard to cost. They shift the blame to consumers who choose only from what options business already decided to provide, as if we're at fault. We are not. Corporations and selfish, narcissistic CEOs and shareholders are the responsible parties. They've been told, shown the science, had it explained it to them personally by the foremost experts, watched the changes unfold, and they keep choosing to kill the planet, and if anyone tries to force them to stop, those systems are relentlessly attacked, like environmental agencies and government oversight, taxation etc.

Us as individuals are not responsible for the choices in business and politics that continue to disregard the warnings, to chase their insatiable psychological need for more power. This is all on them. Every last bit of it and when it finally reaches a point that they can't ignore the consequences, they will force us to sacrifice so they don't have to, even if that means we stop having children or start dying at younger and younger ages.
