To feed the burgeoning human population, it is vital that the world figures out ways to boost food production. Increasing crop yields through conventional plant breeding is inefficient – the outcomes are unpredictable and it can take years to decades to create a new strain. On the other hand, powerful genetically modified plant technologies can quickly yield new plant varieties, but their adoption has been controversial. Many consumers and countries have rejected GMO foods even though extensive studies have proved they are safe to consume. But now a new genome editing technology known as CRISPR may offer a good alternative.
