I do not think it is irrelevant but a part of many factors together with the natural development of the nature. But not that it is the baddest reason and we have to suffer a limited life (you have less rights to many things) and pay money because of it (not to do stuff to mitigate this in an industrial level but put normal people to pay money in taxes of everything. What they eat,buy, uses for transportation. Everything is taxed for CO2 emissions. Really?).... But you know what is tax free? To buy a stupid Tesla car? Really? you do not eat or drink a car as far as I know.
