|More and more people are eating insects
In the past decade, bugs have become a familiar sight on dinner tables. One reason for this is they are a great source of protein. Another reason is that people are concerned about the environment. Traditional livestock farming is detrimental to the environment as it is generally unsustainable. Raising insects is much more environmentally friendly. One kilogram of insect protein needs about 10 per cent of the feed, water and land used to produce the same amount of beef. Experts say farming insects is better for the environment than raising livestock. A final reason we may have to eat insects is because of the rise in the world's population. By 2050 this is expected to be 9.8 billion, up from the current 7.7 billion.
