We are producing fresh, home-grown salad for both the restaurant and our animals and educating audiences about sustainable food production, while researching outputs of VertiCrop. Nature would be less stressed if we all thought carefully about where our food comes from.

I hope our project catalyses the change we need to see - growing food in urban centres, taking pressure off transportation, water and marginalised habitat in the wild, and reducing the embedded fossil energy in crops.

Nature would be less stressed if we all thought carefully about where our food comes from

Paignton Zoo Environmental Park, a conservation, education and scientific charity, plays a crucial role in the conservation of the Sulawesi crested black macaque - a critically endangered primate - with a project in Indonesia and staff working on the island of Sulawesi.

But the zoo is not only dedicated to protecting global wildlife - it also aims to inspire in people a respect for animals, plants and the environment. As a result, the organisation is heavily involved with advances to reduce human impact upon the Earth’s ecological systems.

A good example is VertiCrop, an innovative, high density, vertical crop growing system housed in a modest greenhouse next to Monkey Heights, where the Sulawesi Macaques are housed. Designed to grow crops where they are needed in towns and cities, the system uses less water and land while also reducing carbon footprints and food miles.

So visitors to the zoo, as well as the Sulawesi Macaques can enjoy locally grown mixed salad leaves with little environmental impact.
