Insects, imitation meat to cut environmental impact of livestock.
Insects and imitation meat are the best alternatives to real meat in tackling the huge and growing environmental impact of livestock on the planet, new research has shown.
The world’s appetite for meat is rising fast as incomes grow but the resulting greenhouse gas emissions, already 12% of the total, are also soaring and taming global warming will be impossible unless the trend is reversed. Rising demand is also leading to more of the world’s natural areas being converted to farmland, a key factor in the mass extinction of species currently unfolding.
Globally, twice as much land is used to raise cattle, pigs and other animals than is used to grow crops. Furthermore, a third of those crops harvested are fed back to livestock. The new research is the first systematic comparison of the environmental impact of various sources of food, and found that imitation meat and insects are vastly more efficient than raising livestock.
