There is nothing more important than our own survival. Everything else is secondary. But the point Attenborough is making is that unchecked consumption of the Earth's resources and destruction of our ecosystem in a misguided extreme of survivability. Ensuring our survival requires more than rampant consumption and breeding. We're part of an ecosystem and we need to make sure we're not damaging that ecosystem or putting ourselves in a position we can no longer support. Looking out for the Earth is looking out for us.
Humans in all their arrogance have a tendency to swing to either side of the pendulum. We either vehemently believe our 'progress' and consumption should be unrestricted, as the Earth is there to serve us. Or we willingly endorse self destruction of our species under the deluded belief that an Earth we applied subjective measurements of worth to will be "better off", as if we have any authority on the matter.
It's about finding a position in the middle. Letting go of our ego about what needs to be conserved in regards to the environment and accepting we do need resources and we do need to consume, but also restraining our ego on how much we should be consuming and what freedoms our species really needs.
I agree and don't see why people attack Attenborough. All he's said was more education, more birth control, more environment protection, less CO2 output etc.
And yes, for the last several decades we have been a plague in the sense of rapid growth. While it's true that the growth will slow down in the future, I don't think it's bad to have more education and birth control
now.
Most if not all developed nations are below sustainable rates.
Rates around the globe are dropping. This is what it is based off, it's not just pulling a number out of your ass. China's baby boomer generation is coming in 15-20 years. When that dies off that will be a huge chunk of the Chinese population. Developed countries are all an aging population. So in 100+ years when everyone currently alive is dead, then yes it is easily conceivable to see that the population will massively shrink.
On the other hand, the life expectaction goes up constantly in the industrialized world, perhaps with the exception of the US. And birth rate is climbing again in some industrialized countries. We won't reach 2.1 per female, but it won't stay 1.5 either.
It's funny because average Chinese and Indian can only obtain a fraction of natural resource compared to an American or European. So who is the real plague here?
That's only because there are hundreds of million peasants in China and India. Take them away from the equation, the average chinese in the urban area probably uses more resources than the average European. The 23 of the 26 most polluted cities are in China, go figure.
