  This it may surprise you, but one of the top causes behind global warming and greenhouse effect is the cattle farm. The CO2 emission coming from cattle farms are impacting very badly our atmosphere.
  If we can find an alternative source of meat or animal protein rather than use intensive cattle farm, we could reduce drastically the emission of greenhouse gases.
  This is one of the reasons why there are many studies on the use of insect protein as a substitute for beef and pork meat.
