For ages human time horizons have worked as a succession of generations. With substantial population aging we have many more families where we find 4 generations alive at the same time. In nature and with respect to biodiversity the sequences of renewable have not changed much. Old trees that have been cut will take another 100 years to grow old again. Wild fires or human negligence risk big in this respect. Forests take several human generations to grow and thrive. Diversity is key there as well as many fast growing monocultures have increased risks in case of fires caused by global warming. Annual inspection of a forest that suffered a severe drought and fires is still looking dismal compared to before. (Foret de Senart, France 2025).
