I did see that quote that you had in your study, that the population by the year 2050 is going to increase to so many billions of people and we're going to need to increase food production by 70%. However, current studies show that 30% to 40% of our current food production is lost as a result of wastage in industrialized countries. There are some studies that say that the food scarcity problem in a lot of countries exists because of poverty levels, not really their ability to grow food. There's a real imbalance.
We in the west are lucky to have advanced agriculture techniques. Our farmers, generally and comparatively, are well off. But there have been studies conducted by the United States Department of Agriculture where the yields that have come about from fertilizer use have been so massive that farmers have actually had to sell their crop at a loss. That kind of makes you scratch your head as to whether the system's really working.
Do you have any comments on that?
