    In the last century, there have been a number of discoveries regarding the treatment of human disease and genetic conditions. The current on-going research is in the field of gene therapy, an experimental technique that uses genes to treat and replace the defective genes of an affected person. Instead of treating disease symptoms, this has the potential to correct the underlying cause (1). Besides its high costs and ethical concerns (therapy involving germ line treatment), this technique also poses a considerable amount of risk. Thus, gene therapy is currently only being tested on the diseases for which there is no cure. This article shall look primarily into cystic fibrosis, as well as X-linked severe combined immunodeficiency (SCID), as examples to describe the potential of gene therapy in medicine.…

He gave an example of how we are focused on ourselves that we are affecting others countries. In the Foxconn plant which is located in China had at least fourteen workers committed suicide due to the harsh work conditions, so there were suicide nets placed outside of the windows, and the workers were forced sign pledges not to commit suicide. He also stated that Earth is pushed beyond its limits; we are using 1.5 million of the planet’s resourced causing us to be in an environmental crisis.
