How We Eat May Be Biggest Impact of Urbanization on Nature
"The ecological implications of an increasingly urban world are in an important sense different than the demographic or metaphorical implications. In a world where humanity is overwhelmingly urban, our population dynamics or our cultural evolution will be mostly disconnected with what is happening in rural parts of the world. However, an urban world is still intensely linked with rural areas ecologically - we all need food."
Making sure we're able to provide enough food and farmable land means focusing efforts on improving agricultural efficiency, according to author Rob McDonald.
