For example, in figure 2, one may see the effects fungal disease has on corn. It has made this corn inedible. Next, this disease may spread to other corn within the field or the corn stalk, greatly affecting a certain corn population. With the use of pesticides, corn is able to survive and feed many humans around the globe (PLOS Biology 1). Although pesticides are certainly not good to consume, without them, we wouldn’t have the quantity and quality of corn around the world that we have today (PLOS Biology 1).
