A global push to 7 billion people
The world is becoming a hungrier place - consuming more food, fuel and material resources - as its population bulges. But the increase in consumption is not even and not driven by the same factors. China and India are consuming more because their populations have vastly increased in the past 40 years. The United States, Japan and many countries in Europe are having much less population growth, but the people are using more resources. Meanwhile, many in South American and African countries have had relatively small population growth and much less increase in consumption.
