There should be critiques on the write up of a transgenic species. E.g. the BT cotton may destroy natural populations...or because of a transgenic species advantages it may become overly dominant in the population chaing the genetic make up. This would leave the species open whereby the transgenic species may have a flaw to a certain environment that the natural population would have been resistance against. Therefore, the species may die out.
There's also ethical responses. Take note, the specific dot point in the syllabus refers to all GM modifications, not just transgenic species.
