Final answer:
Chemistry has led to advancements such as new materials and batteries, positively affecting modern society. However, it has also introduced pollutants that harm the environment and are linked to global climate change, exemplifying a negative effect.
Step-by-step explanation:
Positive and Negative Effects of Chemistry on Society
Chemistry plays a crucial role in society, providing numerous benefits as well as posing certain challenges. One positive effect is the development of new materials and batteries, which are essential for modern technology and energy storage. On the other hand, chemistry has also introduced persistent chemical pollutants such as CFCs and PCBs into the environment, leading to potential long-term ecological and health issues.
The use of chemical reactions for generating energy, as seen in the combustion of fossil fuels and other materials, is another example where chemistry has significantly impacted society. While enabling essential activities like electricity production, transportation, and industrial processes, it also contributes to global climate change, a major concern recognized by the scientific community.
