Biotech, short for biotechnology, is a field that uses living organisms or their components to develop products and technologies. This can include everything from creating medicines and vaccines to improving agricultural crops. By manipulating biological systems, scientists aim to solve problems in health, food production, and environmental sustainability. The applications of biotech are vast and impactful. For instance, genetic engineering allows for the modification of plants to resist pests, while CRISPR technology enables precise editing of DNA in various organisms. Overall, biotech plays a crucial role in advancing science and improving quality of life.
