Seven Billion - and Counting
The human population of Earth has reached seven billion. This Catalyst article explores the impact that human activity may have on the planet.
The article looks at the rate of population growth and how human impact is also related on the amount of resources used by an individual. It considers if the effects of human activity could lead to a mass extinction on the scale of previous events, such as the one that saw the disappearance of the dinosaurs 65 million years ago.
The resource can be used to stimulate discussion on topics such as sustainable development, renewable and non-renewable resources and population growth.
