The motivation for that kind of infanticide is obviously reproductive. I have seen video of Silverbacks smashing the infants of competing males against rocks and tree trunks, swinging them by their legs.
The cannibalism in your links is only secondary to the infanticide.
Not hunger or starvation.
"Our common ancestor was probably also a cannibal."
Your and chimpanzee's common ancestor.
Or your and my common ancestor?
You're harming the planet as a whole by releasing all that buried carbon.
Sure. We're at Peak Oil. We have burned half of it all, already. We just had the longest winter, and the largest amount of snowfall in California, and lastest snowfall in California in my memory(probably in recorded history). If we are warming the planet with carbon dioxide, its a good thing because we would be having blizzards right now if not. Highway 4 at Ebbets Pass was still closed July 4 because of snow, its usually open in May.
Just as pre-petroleum society was harming the planet by killing whales for fuel.
It harmed the whales, it didn't harm the planet.
You shouldn't use it, and future humans shouldn't use it.
At least we now agree that I don't actually have to save any for them. And there is no morality involved in not saving some for them, you think they shouldn't even use any.
It is both necessary for life and harmful. It's a question of quantity, like oxygen for you.
Ok, we both know that we have used up about half of the total planet's oil reserve, and burned it already. Leaving half remaining, which is going to start getting really hard to get to. That means that half the total amount of CO2 has already been released as waste. At worst, we are going to double the amount of CO2. And its going to take a very long time to get to that second half, because its going to get much harder to get to, so a longer time than what we have used up burning the first half of the total(agreed).
What does your model say when CO2, not total just what we release, is going to be double?
Hydrogen is very light
I will worry about that in 3 billion years, ok? I don't think it is a reasonable problem in the foreseeable future.
But unless you're planning on dying very soon, it's going to affect you too.
Some time between a year from now and 20 years from now. I sure hope I don't make it 30 more.
