I'm aware that it's just a belief, not a fact. I'm aware that many before me have predicted doom...and been wrong, often ridiculously, humiliating wrong (Ehrlich).
I believe that we only need to sustain increasing productivity, not populations, and not raw land. In fact, less land is being cultivated with higher productivity in the United States, than was the case 50 years ago.
I agree 100%. If we can do this we're home free.
But even though it seems we can, it's not clear we will. So it's my function to continually point out what will happen if we don't. To point out the dangers, the signs of resistance and back-sliding.
Of course, we could both be wrong and the world could be moving in directions unseen by either of us. How many times before has that happened....
Many more times than not... forecasting the future is very difficult. I think the most likely future will be something that neither one of us has imagined... but, I am optomistic about it.
