Possibilities offered by genetic engineering

• Treatments for currently incurable diseases such as cystic fibrosis, Alzheimer's disease and Down's syndrome could be developed through genetic engineering
• It is thought that within a generation, it will be possible for parents to select the DNA that would lead to their offspring being super-intelligent or super-fit (genetic enhancement therapy). These are known as 'transhumans'
• Genetically modified animals have produced a human protein in their milk that has been used to treat some people with lung disease
• Crops genetically modified to produce significantly larger crop yields and to be disease-resistant could help to address the problem of global hunger
