Recently, it has been reported that human proteins can be produced in genetically engineered rice. The company expects to have regulatory approval within seven years for some of the medical products derived from transgenic plants. Cloning The production of one cloned sheep involves killing several sheep and subjecting a number of others to surgical interventions. Firstly, a donor ewe undergoes surgery to remove her egg cells. After a few days this 'foster mother' ewe is killed and the embryo extracted.
Cloned animals are sometimes abnormal.
Moreover, cloned foetuses sometimes grow abnormally large, leading to painful or caesarean births. Widescale cloning of livestock could spell disaster for farmers. In a herd of cloned sheep, all the animals would be similarly vulnerable to the same disease pathogen. In the longer term there could also be considerable loss of genetic diversity. Many of CIWF's concerns are shared by the European public.
