Key Concept:
Biology and technology influence human life and the environment in both positive and negative ways, shaping health, agriculture, ecosystems, and ethics.
Short Notes:
Biology has improved our understanding of health, nutrition, and the environment. It helps us discover treatments for diseases, understand how our bodies function, and protect biodiversity. For example, biological studies have led to better vaccines, improved sanitation, and protection of endangered species. These benefits show how biology supports societal development.
Technology, when combined with biology, has created powerful tools such as genetic engineering, cloning, and advanced medical imaging. These tools improve life but can also cause harm if not used wisely. For instance, overuse of fertilizers and pesticides (a result of agricultural technology) can damage ecosystems and water sources. Therefore, technology must be applied responsibly to avoid harming the natural world.
Key Terms:
- Impact – The effect or influence of something,
- Society – A group of people living together in a community,
- Natural World – All living and non-living things in nature,
- Genetic Engineering – Changing an organism’s genes for specific outcomes,
- Cloning – Producing identical copies of organisms,
- Ecosystem – A community of living things interacting with their environment,
- Biodiversity – The variety of life in a given area.
Example:
In Ethiopia, biological knowledge is used to control the spread of diseases like malaria and improve local farming through natural pest control methods.
