I think it might mean different things for different people, but the world's population is growing. As some areas that have historically been more economically disadvantaged become more economically affluent, dietary preferences are changing. Many areas people have more meat, will want to eat more meat which requires more feed to be produced. Again, calling into production more acres of land. Combine with the loss of environmental resources and the importance of sustainable agriculture becomes pretty clear.
Modern biotechnology can help in many ways.
I think there are people who certainly have some concerns, but what it is as I use the term, what I meaning is the transfer of genetic information or DNA from one living organism to another to achieve a desired trait. First of all we'll discover a gene that we believe have the characteristic that could be important. Then we'll transform a plant or what we are doing there is inserting that gene into plant tissue. We'll grow that plant, produce seeds from that plant and make sure that the genetic trait is present and that the plant still functions normally in every other way. That the only thing that happened was the insertion of the gene into that plant.
