Episode notes
Food Production Drives Planetary Harm
- Global food production is a major driver of environmental damage and biodiversity loss.
- Meeting 2050 demand requires ~50% more food while freeing 30–50% of land for nature, creating an existential challenge.
Production Method Beats Distance
- Food miles matter but production method and food type often outweigh distance.
- Beef has a far larger carbon footprint than pulses, and British beef emits much less than South American beef.
Adopt A Flexitarian Diet
- Eat less meat and shift to a flexitarian diet to cut emissions and improve health.
- Increase consumption of fruit, vegetables and pulses for nutrition and food-security benefits.
