Biotechnology applications involve using living organisms or their components to develop products and technologies that improve our lives. This includes areas like medicine, where genetic engineering is used to create vaccines and therapies for diseases, and agriculture, where genetically modified organisms (GMOs) are developed to enhance crop yield and resistance to pests. Another significant application is in environmental management, where biotechnology helps in waste treatment and pollution control. For instance, bioremediation uses microorganisms to clean up contaminated environments, while biofuels are produced from organic materials, providing a renewable energy source that reduces reliance on fossil fuels.
