At present, scientific research across the world is carried out and controlled sometimes by governments, sometimes by private companies. While there are some arguments in favour of scientific research by corporations, I agree with the view that this should be funded and supervised by the state. The private sector argues that it is willing to undertake scientific research, but there are two significant dangers in this. In terms of the quality and objectivity of the research itself, corporations that carry this out may be tempted to manipulate results in order to maximize profits. There have been numerous scandals as a result of new products being introduced hurriedly after inadequate trials. For example, thalidomide, developed by a German drug company, resulted in the birth of thousands of malformed children. From an ethical perspective, leaving research into areas such as genetic engineering in the hands of corporations may have profound social consequences -such as GM crops, with unproven effects which may destroy whole ecosystems as a result of meddling with nature. Although governments have to allocate resources to many areas of public spending, it is essential that they be responsible for scientific research.
