The two mainstream are options are: pretend that the elephant doesn’t exist. A strategy that had some currency back in, say, 1970, when the end game was 60 years off, less so now. Or you just sit there and say that science will come up with a solution. Again, ask yourself, would you invest in a company that told you this? Worse still, the relatively low-ball population ceiling predictions that had lulled everyone into thinking we’d be OK are starting to look very conservative indeed. That reassuring nine billion figure is unlikely. What is now more likely is 11 billion plus, all of whom will, on average, be consuming more methane-generating cows than we do today.
