This is the world of factory farming. In these generic looking sheds, live thousands of animals, caged and deprived of all freedom.

Spending their lives in cages, chickens are turned into egg-laying machines.

No room to flap their wings.

Spending their lives standing on wire watching their eggs role past.

How many people think about what suffering lies behind their neatly packaged supermarket egg.

Pregnant female pigs are some of the most cruelly treated animals in the world. This is their maternity suite, commonly called a 'sow stall' by the industry.

Pregnant pigs give birth in a 'farrowing crate'. Piglets are born into a world of concrete and steel. The only time they will see the sun is on the way to the abattoir.

Factory farming is growing and being used for other animals like sheep and cows. The time to end the injustice is now.
