The Pros and Cons of Genetically Modified Crops
The year 2015 marked the 20th year of the commercialiaztion of genetically modified (GM) crops. During the period from 1996 to 2014 the global hectarage of these crops increased 100-fold, making it the fastest adopted crop technology in recent times. But what are the downsides of this technology? In this review I look at some of the problems related to weeds becoming resistant to the main ingredient, glyphosate, that is used on herbicied tolerant crops, how these can be overcome and whether glyphosate can cause cancer. I also discuss the problem of insects becoming resistant to the toxins that are used in insect resistant crops and how these are being addressed. I look at what scientists around the world are saying on this topic and then consider GM crops that are in the pipeline and whether any of these are likely to be commercialized in the foreseeable future.
