Human beings are ultimately nothing but carriers-passageways- for genes. They ride us into the ground like racehorses from generation to generation. Genes don't think about what constitutes good or evil. They don't care whether we are happy or unhappy. We're just means to an end for them. The only thing they think about is what is most efficient for them. Haruki Murakami. Scientists are seeking to develop new methods and techniques in order to ensure the food security.
