Population and the environment

Our numbers have a huge effect on our natural environment. The more of us there are, the bigger the impact on nature. Human population growth is a key driver of biodiversity loss, resource depletion, deforestation, climate emissions and pollution.

In the 1970s, Population Matters Patron Paul Ehrlich and his colleague John Holdren developed an equation to describe our impact on the environment:

I = P x A x T

Where "I" is impact, "P" is population, "A" is affluence and "T" is technology. The "IPAT" equation shows that our numbers, how we live, and the technology we use all have an effect on our finite environment.
