Reading Passage:

Artificial light has become an integral part of modern society, but its impact on wildlife is increasingly concerning for environmental scientists. Firstly, artificial light disrupts the natural behaviors of nocturnal animals. Many species rely on darkness to hunt, mate, and navigate, and excessive lighting interferes with these activities, leading to reduced survival rates. Secondly, artificial light pollution affects migratory patterns of birds. Birds use natural light cues for navigation during migration, and the presence of artificial light can disorient them, causing collisions with buildings or leading them off course. Lastly, the proliferation of artificial light has been linked to the decline of specific insect populations. These insects are often attracted to lights, where they become prey or perish, disrupting the food chain and affecting biodiversity.

Lecture Script:

While the reading passage highlights concerns about artificial light, it's important to consider other perspectives. Firstly, regarding nocturnal animals, some species have shown adaptability to artificial light, adjusting their hunting and mating behaviors accordingly. Some even benefit from the increased visibility to spot predators or prey. Secondly, while artificial light can affect bird migration, advancements in lighting technology, such as shielded and motion-sensor lights, are being developed to minimize disorientation. Lastly, the decline in insect populations is not solely attributable to artificial light; factors like climate change and pesticide use play significant roles. Therefore, while artificial light has impacts, it is not the sole or most significant threat to wildlife.

Sample Essay:

The reading passage asserts that artificial light negatively impacts wildlife by disrupting nocturnal animals, affecting bird migration, and contributing to insect population declines. Conversely, the lecture offers counterarguments to these points. The reading claims that artificial light harms nocturnal animals, but the lecture suggests that some species adapt by modifying their behaviors, potentially benefiting from increased visibility. Regarding bird migration, the reading highlights disorientation caused by artificial light; however, the lecture notes technological advancements like shielded lighting that reduce such effects. Lastly, while the reading links artificial light to declining insect populations, the lecture points to other significant factors, such as climate change and pesticides, that also contribute to this issue. In conclusion, while artificial light poses challenges, it is not the only or most critical threat to wildlife.
