Biotechnology and Ethics
New biology raises ethical questions.
About this topic
Biotechnology applies biology to create products: GM crops, gene therapy, cloning, stem cell treatments, genetic testing and CRISPR. These offer benefits such as new cures and food security, but raise ethical questions: Is it right to modify embryos? Who owns genetic data? Could it widen inequality?
Ethics means deciding what is right and wrong, and in science it involves weighing benefits against risks and considering different viewpoints. CRISPR allows precise editing of DNA, potentially correcting genetic diseases such as sickle cell, but editing embryos would pass changes to future generations, which many find troubling.
Consider genetic testing: it can tell someone they carry a disease gene, allowing early treatment, but could lead to anxiety or discrimination by insurers or employers. Stem cells can grow tissue for repair, but embryonic stem cells involve the destruction of embryos, which some people oppose. Designer babies raise fears of choosing traits.
Decisions are made through laws, regulators and public debate, and different countries have different rules. A good approach is to use evidence, listen to all stakeholders and consider fairness. Students should remember that science tells us what can be done, while ethics asks whether it should be.
