Since my topic is light pollution, I think it’s only fitting to draw attention to the invention of the incandescent light bulb, which most agree was invented by Thomas Edison. Without such mass market lighting technology widely available, we wouldn’t have any light pollution because we’d barely have any light! There are many additional functions of electrical light that contribute to light pollution, such as AC power (Nikola Tesla) which has enabled electricity to be transported extremely long distances from its source, but ultimately, the light bulb is responsible for light pollution. Thomas Edison (in collaboration with other scientists) developed the incandescent bulb and changed the world really. We are so dependent upon artificial light nowadays, our world would be very different without those lights. Although they are very useful, we need to find ways to target lights in places where they are needed to avoid waste lighting which contributes to light pollution. We also need to consider the most efficient applications for light, and where they pose the greatest harm to the environment.

When responding to your peers’ posts, consider how the work of the scientists they chose has influenced the modern world. Why does their research matter to us as individuals? Are there any connections to the natural-science topic you identified in your news article?
