With CA comes the idea of producing enough food. With cutting back in fertilizer, not tilling the ground, and other processes comes the responsibility to feed the world. According to the Population Reference Bureau, there were around 6.08 billion people on Earth in the year 2000. By 2050 there will be an estimated 9.1 billion people. With this increase comes the responsibility for producers to increase food supply using the same or less land than we use today. Problems arise in the fact that if CA farms do not produce as much as conventional farms, this leaves the world with less food for more people.
