What is BT cotton?

BT cotton is geneticly modified to contain a natural toxin created by a bacteria whos initials are BT. the bacteria as well as its toxin have long been used in organic farming as it is only activated in a highly basic (as in not acidic) envirument which is rather rare in nature execpt for the digestive system of several butterflies one of which is a major pest in cotton crops (i think its called pink worm something but its been a while). anyway the use of such plants mean many chemical treatments will be made redundunt which is good for the consumer as well as the envirument and the farmer. it has also been proven that although there is the ability to develop resistence to the toxin (in the lab) the living cost of of this resistence prevents its build up in nature. that along with the law that stats one has to grow at least 20% of the area with non BT plants aliminates the risk of its efectivness being damaged over time as happens to so many pesticides
