How Does BT Corn Help Humans Change The World
The new Bt corn is genetically modified with a certain gene that when a caterpillar or other harmful insect/animal tries to eat the corn they die making it so there is less corn being eaten. Caterpillars alone cost over $1 million in damage to farms all over the world. Also because of the gene being genetically modified into the corn that means that all of the non-harmful insects/animals aren't effected by the corn unlike when it was a sprayed on insecticide. One non harmful insect is the beetle, without the beetles there wouldn't be as much insects eating the weeds that are growing in the corn yeilds. Without these beetles there would be a decrease in corn yeilds which would cost even more damage adding onto the damage caused by the caterpillars.
When the insecticide was sprayed onto the corn it could often infect the pollen which means when the bees come to pollinate the corn they could get infected and die. Without the bees, like without the beetles, there would be a decrease in corn on farms because there is less bees to pollination all of the corn meaning less money being made from the corn.
The new BT gene helped the corn to when the insects started eating the crop they died in a rather short amount of time compared tot he insecticide.
Since the first time BT corn was introduced to farmers the amount of corn and other crops that has a genetically modified gene in it has risen by a lot. In 2012 about 88% of all corn was GM with the BT gene inserted into it. In 2013 93% of all corn had the BT gene in it. Now about 70-80% of all of Americas processed food has at least 1 GM gene in it.
