I put forth the basic conundrum we all face four years ago when I joined. Perhaps it is time I again rubbed the grim facts in your faces.
7.5B human beings is simply an unsustainable number. That many people, even if each were an ardent environmentalist living a low impact lifestyle, would still be driving the planet rapidly into mass extinction. Recall that the present rate of plant/animal/etc. species extinctions is unprecedented in the fossil record. The presence of 7.5B Kudzu Apes is the deadliest condition ever experienced by this planet called Earth.
They are already here, and the majority have only marginal lifestyles by First World standards, and they all want what we have - health, clean water, enough food, bountiful energy, and toys. But there isn't enough stuff on the planet to give them that, and if we attempt to do so, we will be killing the planet more rapidly.
When we just look at China, if we were to simply bring that 1.379B (2016 figure from wiki) up to Western standards, there is not enough refinery capacity, let alone petroleum. Not to mention, some demographers claim tha India surpassed China as the Earth's most populous country this year.
You as an individual have two viable choices:
1) Become an advocate of Gaia, Mother Earth, Nature, the Living Planet, the Planetary Ecosystem, whatever you want to call it, and of preserving the same. This necessarily involves advocating genocide of all humans everywhere on the planet, for the sake of all other species. The idea if taken to an extreme involves mass human suicide, and a dwindling number of humans acting as caretakers, healing the broken ecosystem, before dying without reproducing. In any case, 7.5B, or 10B or more dead humans.
2) Become what you already are by the way you are living, which is a destructive species that is killing the ecosystem faster than the Chicxulub impactor did when it struck the planet 65M years ago and cashed in the chips for the dominant dinosaur species. As the population grows, we take over the ecosystem and simplify it, until only humans and their food species remain.
Yes, that's a discription of two extremes. I won't deny that there are a wealth of positions between them. I take the second path as an advocate of humanity. That does not prevent me from being saddened by the deterioration around me, I have been watching the world decline for decades. My only other point is that the two extremes are the most viable paths, and that attempting to walk some middle path IMHO does more damage in the long run.
Those of you who have chosen to hide somewhere that does not rub your face is the basic choice man vs. planet, are hiding rather than making this choice, pretending - along with the majority of humans - that no choice is necessary.
