Fast-growing global population. No additional land for agriculture. Climate change. These three pressures, linked through the process of food production, will become more daunting as we move toward 2050. That is the year, predicts the United Nations, when the world population will reach nine billion.
To feed that many people, as much as 50-per-cent more food will be needed. Much of that food will come from agriculture. Yet other UN data shows that the amount of land suitable for agriculture has plateaued. In the future, our children and grandchildren will live in a world with many more people to feed from the same agricultural land area we use today.http://ottawacitizen.com/opinion/columnists/gregorich-dont-jeopardize-long-term-farm-research-for-a-hospital-site
