We have been doing that. But one problem is that it's easy to fool ourselves: you can temporarily raise carrying capcity by eating capital. So, we catch many more fish now, for example. But we are catching at faster than replacement rate, depleting the natural capital stock. Carbon energy + space in the atmosphere for CO2 is another variety of capital stock which we have used for temporary carrying capacity gains. There are also long run carrying capacity improvements in the mix. General efficiency improvements fall in this category.
