In  past decade, bugs have become  familiar sight on dinner tables. One reason for this is they are  great source of protein. Another reason is that people are concerned about  environment. Traditional livestock farming is detrimental to  environment as it is generally unsustainable. Raising insects is much more environmentally friendly. One kilogram of insect protein needs about 10 per cent of  feed, water and land used to produce  same amount of beef. Experts say farming insects is better for  environment than raising livestock.  final reason we may have to eat insects is because of  rise in the world's population. By 2050 this is expected to be 9.8 billion, up from the current 7.7 billion.
 insect farming industry is growing quickly. There are hundreds of companies worldwide creating meals made from bugs. Many supermarkets around  world now stock food made from insects. There are vending machines in Tokyo, Japan where you can purchase  can of insect snacks.  menu includes dried tarantula and scorpions. However, not everyone is excited by  idea of insects as food. An Israeli insect farmer, Dror Tamir, says there is  "yuck factor" to the thought of eating insects. He said people will get used to  idea and will find insects tasty. He said: "I am convinced it will soon be widely accepted, just like eating raw fish in sushi was embraced."
