We want land for so many of humanity's growing needs, such as food for an expanding population, renewable energy, carbon storage, flood water and timber.
Traditionally we have stolen it from Nature, but the resulting toll of pollution and extinction is now punishing us.
Tom Heap (Countryfile, BBC Radio 4) has toured the British countryside meeting farmers, scientists, conservationists and even warehouse managers who are finding solutions to this geographical crunch. Use land cleverly and we can give both Humanity and Nature the space to thrive.
