Second, is a genetically engineered corn. The corn is engineered to be insect resistant which when the milkweed plant grows on the edges of the fields, the studies have shown the monarchs are being killed (Stix, 1999). Lastly, is the interpopulation of the monarch butterfly. The monarchs live on both sides of the Rocky Mountain Range. Some scientist have taken the monarch west of the Rockies and mixed them with the monarchs east of the Rockies and vice versa. There are two arguments against this interpopulation. First, transferred butterflies can bring infectious and lethal diseases into new populations. Second, transfers may hurt or confuse our understanding of the biology of the monarch. With all these different ways man is endangering the monarch butterfly; it makes us wonder what can be done about it (Brower, et al, 1995). In Mexico, a man by the name of Jose Luis Alvarez, is working to teach the local ejidatarios on how make better use of their land (Clattenburg, 2004). In the past ten years, he claims he has plant over a million new trees to help with the deforestation and the demise of the monarch (Clattenburg, 2004). In the US, the corn industry is hurting by the genetic engineered corn. It cannot sell the corn to European markets so the engineered corn is not the premium corn on the market. With the help of Alvarez, Mexico will still be the place of the monarchs winter home, and the human race
