Genetically Modified Food is a blessing. GM food is crops modified to enhance desired traits‚ and promises to meet the demand for food for this booming population in the near future. GM food allows modified crops to be pest-resistant‚ herbicide-tolerant‚ disease-resistant‚ cold-tolerant and drought-tolerant or salinity-tolerant. Pest-resistant crops prevent farmers from incurring huge losses from insect pests. This trait also allows non-usage of chemical pesticides‚ which are typically used in
