Happy Earth Day to everyone! In today's milieu, it is impossible for most of us who read the papers and watch the news on television to be unaware of our environment and how we are all contributing to its degradation. Even then, most of us don't give a thought to what we choose to eat. There's a great demand from conservationists that we should eat `local' -- whioch means food that has been grown locally and has not travelled a long distance to reach your dinner table. The distance it travels is measured by Food miles. The more miles an item of food has travelled, the less sustainable it is because so much energy has been burnt up and Carbon dioxide emitted during its journey. So in India, when we eat Japanese apples or Californian grapes, they may taste great but the fact is that making such choices is bad for us and bad for our planet.
