Case Study on CRISPR-based gene drives

Synthetic gene drives based on the CRISPR-cas9 genetic engineering method could be used to spread artificially modified genes through wild populations faster. The main promise of this technology is that it spreads itself: the gene drive is inherited by each next generation of offspring. This could make it possible to enhance, suppress or perhaps even eliminate a population. So far, CRISPR-cas9 based gene drives research has been limited to the lab, and has focused mainly on mosquito species that transmit malaria.

Taking stock of the precautionary principle since 2000

The precautionary principle is supposed to enable decision-makers to adopt precautionary measures even if scientific uncertainties about environmental and health risks remain. However, opinions about the precautionary principle are divided. To some, it is unscientific and an obstacle to progress. To others, it is a necessary tool to protect human health and the environment.
