Will the planet be able to feed future generations? This question is by no means a new one, but the context in which it is being asked is. In the past, many worried that the ever-increasing rate of population growth would leave us with simply too many people to feed. However, the combination of huge increases in crop yields and evidence that the rate of population growth is slowing has redirected attention away from the issue. The original question, however, is still hotly debated.
In recent years, many have argued that our food system is not sustainable, meaning it is damaging the environment to such an extent that it will be unable to support the demands of the future. One of the reasons this has become an issue is because of the global transition towards a diet containing more meat, alcohol luxury foods. These types of food take a great toll on the environment because they require more agricultural inputs than they supply to the consumer. For example, Michael Pollan explains that it takes about 10 lbs of grain to produce 1 lb of beef. Another problem is that the intensive cultivation of non-rotated crops with large additions of fertilizer severely depletes the soil. Warren Belasco in “The Future of Food” argues that the shifts and innovations that have made possible the unprecedented quantity and variety of our current food system also have unintended consequences that will trouble future generations sooner than we think.
Belasco identifies two types of possible solutions to this crisis. The first is the technological fix. In this solution profit-seeking free enterprise will continue to innovate and will eventually solve sustainability issues with technology. In my opinion, however, we have already done too much damage for this solution to work alone. The second solution is the anthropological fix. In this solution future generations will have to change their attitudes about food. People will adopt more environmentally friendly diets, such as vegetarianism, and forget their desire for unsustainable foods such as cheap beef. Belasco recognizes that the future may need to require a combination of the two options.
Will the planet step up and work make our food system sustainable before its too late?
Are the current fears just like the fears of population growth from the past? Meaning that the global economy will just naturally find a solution?
