Biotech crops have been promoted since 1996; however, some food activists have expressed concern that biotech crops are not as safe as conventional crops. People need to be better informed about food production as agricultural biotechnology becomes more widely used around the world. Biotech crops are currently preferred by over 15 million growers in 29 countries. According to the UN, the world's population will grow by one-third to 9.1 billion people by 2050. This will require a 70% increase in agricultural output. Food biotechnology has proven to be an important tool in addressing the challenge of increasing our food supply while remaining safe and cost-effective.
