The government needs to tackle the UK's "failing food system" by linking its policies on health, environment and education, a committee of MPs has said. The Environmental Audit Committee said a focus on sustainable intensification - or increasing food yields - risked "damaging the environment and society". It called for gardening and cooking to be part of school curriculums, and for stricter junk food advertising limits. Defra said it was trying to boost food production at less environmental cost. "We spend £400m a year on agriculture and food research, we're close to publishing the ambitious Green Food Project to make the whole food chain as sustainable as possible," a spokeswoman said.
