Meat the challenge: sustainable diets

• sustainable 可持续性的

Today sees the first scientific targets set for a diet that is both healthy and sustainable, published by the Lancet, a medical journal.

The review also outlines actions that can speed the transformation of the food system.

Food production is a major source of greenhouse-gas emissions, the main user of fresh water, and a leading driver of biodiversity loss and land-use change.

• greenhouse-gas emissions 温室气体排放
• driver 驱动因素
• biodiversity 生物多样性（大量各种生物的共存以维持生态环境平衡）
• land-use change 土地利用变化；土地改变使用的影响；土地利用旳改变

At the same time, unhealthy diets are behind growing rates of diabetes, heart disease and cancer.

• diabetes 糖尿病
• heart disease 心脏疾病

This points to a need to change farming and eating if the world is to sustainably feed 10bn people by 2050.

• farming and eating 农业和饮食

One likely area of focus will be meat, which has an enormous footprint, with more than 80% of farmland being used for livestock.

Meat production is responsible for large losses of wildlife habitat, but provides relatively few calories—around 18% of the global diet, according to a study earlier this year.
