Pick of the Day

Chris Packham: 7.7 Billion People and Counting, 9.00pm, BBC Two

According to the UN, the human population could reach ten billion by the year 2050. That's a lot of people.

For broadcaster and naturalist Chris Packham, who has dedicated his life to championing the natural world, the subject of our growing population and the impact it is having on our planet is one of the most vital - and often overlooked - topics of discussion in an era of increasing environmental awareness.

Travelling around the globe in search of answers to difficult and sometimes controversial questions, Chris investigates why our population is growing so rapidly, what impact it is having on the natural world, and whether there is anything that can be done.
