Is opposition to biotech crops by some environmental groups slowing down the growth of this promising technology?  Apparently not, as global acreage devoted to such crops jumped 15% last year – the seventh straight year of double-digit growth.  According to The Washington Post, a million more farmers adopted the crops worldwide, raising the total to 7 million. Indeed, some of the world’s largest countries, including Brazil, India, and Indonesia recently embraced the technology, and there are millions of small, peasant farmers in China now growing biotech cotton.  Even though genetically modified seeds can cost twice as much as conventional ones, the massive benefits of higher yields and lower costs for labor and chemicals suggest a continuing boon for biotech.
