While incremental improvements are being made to crop yields, food production needs a major boost. Some suggest production will need to double in the next 30 years. A more efficient photosynthesis will lead to better yields and some simple plants employ this already. It is seen in a single cell in some blue green algae. Ben Long is part of work being undertaken in labs all over the world hoping to capture the more efficient photosynthesis and apply it genetically to crop plants such as cassava, soy beans and rice.
