How does climate change affect biodiversity and society?
How does climate change affect biodiversity and society? As climate change alters temperature and weather patterns, it will also impact plant and animal life. Scientists expect the number and range of species, which define biodiversity, will decline greatly as temperatures continue to rise. Why is climate change a threat to biodiversity? The risk of climate […]
How can theories change?
How can theories change? Theories may change, or the way that they are interpreted may change, but the facts themselves don’t change. Tanner likens theories to a basket in which scientists keep facts and observations that they find. The shape of that basket may change as the scientists learn more and include more facts. What […]
