Prof. Judith L. Capper has spent the last 5 years researching the environmental impact of dairy systems and how this can help us as we try to grow more food with less land for the estimated 9.3 billion people in 2050. Capper’s research discovered that jersey cows don’t produce as much milk as Holsteins but they do produce more cheese. So is jersey cow production the future? According to Capper, producing 500,000 tonnes of cheddar cheese from jersey cows will save 1.71 MT of CO2, the equivalent of taking 337,000 cars off the road and 252 billion litres of water which could supply 4.3 million people per year.
