With this method, plants themselves can produce the proteins and protect themselves from insects without any external Bt and/or synthetic pesticide sprays. In 1999, 29 million acres of Bt corn, potato and cotton were grown globally. Bt crops are protected specifically against European corn borer, tobacco budworm, cotton bollworm and the Colorado potato beetle.
    Benefits:
    • Reduced environmental impacts from pesticides – When the plants are producing the toxins in their tissues there is no need to spray synthetic pesticides or apply Bt mixtures topically.
    • Increased opportunity for beneficial insects – Bt proteins will not kill beneficial insects.
    • Reduced pesticide exposure to farm workers and non-target organisms. 
    Potential risks:
    • Invasiveness – Genetic modifications, through traditional breeding or by genetic engineering can potentially change the organism to become invasive. Few introduced organisms become invasive, yet it’s a concern for the users.
    • Resistance to Bt - The biggest potential risk to using Bt-crops is resistance. Farmers have taken many steps to help prevent resistance.
    • Cross-contamination of genes - Although unproven, genes from GM crops can potentially introduce the new genes to native species.

    - Richter’s scale: a way of measuring the strength, or magnitude, of an earthquake - it’s a logarithmic scale
    - seismograph: an instrument that is used for measuring the strength of earthquakes
