1, the first is the threat of gene technology abuse. Technology has always been a "double-edged sword", just as nuclear technology can be used to generate electricity for the benefit of mankind, and it can also be used to destroy mankind in war.
2. With the development of molecular genetics and related technologies, we have to think about the question of "what is man". As critics have repeatedly stressed, genetic and reproductive engineering seriously endangers human nature and related humanitarian and human problems.
3. Genetic discrimination and the concept of equality are also worth discussing. With the development of gene technology, a new kind of discrimination-genetic discrimination has appeared in human society.
4. Genes are limited resources. The human body has about 40,000 genes, and the human genome has only one set. Whoever has more genes will have an advantage in the commercial development of genes. The way of gene possession is "gene patent", which ensures the owner's high monopoly on gene application.
