(EXPRESS) — Experts urged westerners to become “demi-tarians” by halving the amount of meat they eat.

A report for the UN Environment Programme said that pollution from fertilisers is threatening human health and the environment by causing phenomena such as toxic algal blooms.

It said that 80 per cent of the nitrogen and phosphorus used in fertilisers is consumed by livestock because it is used to grow the crops they eat.

The scientists, led by Professor Mark Sutton of the UK’s Centre for Ecology & Hydrology, said eating smaller portions or having meat every other day would help slash pollution.
