Jennifer Doudna, a co-developer of CRISPR, emphasises the transformative potential of the gene-editing technology in combating climate change through the development of resilient crops and animals. She highlights that CRISPR’s precision allows for faster and more targeted genetic modifications compared to traditional methods, enabling the creation of plants and livestock suited to extreme climates. Examples include cattle with shorter coats for hotter temperatures and crops engineered to withstand storms, drought, or promote carbon sequestration. Regulatory adjustments in the US have facilitated the deployment of CRISPR-edited crops, particularly those mimicking natural genetic changes, which avoid bioengineered labelling requirements.
The Innovation Genomics Institute, founded by Doudna, is exploring applications such as methane-reducing cattle microbiomes and drought-resistant rice, showcasing CRISPR’s capacity to address agricultural and environmental challenges. However, obstacles persist, including regulatory complexities, intellectual property disputes, and concerns over consumer acceptance of genetically edited products. Critics argue that the current rules lack transparency, although Doudna maintains that the US regulatory approach balances safety with innovation. She stresses the importance of responsible use to harness CRISPR’s potential while mitigating risks, positioning it as a critical tool to address global challenges like food security and climate adaptation.
