How will transgenic animals impact the environment?
Some opponents of this technology consider “highly mobile” transgenic animals, such as fish and mosquitoes, to be of some risk to the environment. The principal concern is that genetically engineered animals may escape into the wild and breed with natural populations, which may harm those populations and their environment. Those developing transgenic animals seek to identify such risks and proactively work to minimize the factors that have the potential to cause environmental problems.
