Population Matters



Humanity relies on ecosystems and biodiversity for its well-being in many acknowledged and some unacknowledged ways. Yet we are systematically reducing the quantity and variety of the natural world through development, pollution — including climate change — and resource exploitation. We must preserve nature through limiting our consumption and population to sustainable levels.

We rely on the world’s ecosystems and rich biodiversity for everything we need to exist, from the regulation of our atmosphere and the pollination of plants to the creation of important new medicines and crops.


The value of biodiversity lies in both the range of species and the genetic differences within species.

We are reducing this crucial diversity through development, exploitation and pollution; our numbers and activity increasingly encroach on the natural world. Our impact on biodiversity takes many forms, and population growth significantly contributes to virtually all of them.

Climate change, itself arguably caused by human activity, particularly in the industrialized world, is also playing a part in the rapid decline of global biodiversity.

We are putting already limited space and amenities under yet more pressure.

In summary, the more of us there are, the greater is our impact on the environment.
