From the video, what do you see is the impact of an oil spill on light entering the water?

As a text-based AI, I'm unable to watch videos or perceive visual content. However, I can tell you generally that an oil spill can significantly impact light entering the water. The oil forms a layer on the surface of the water, which can block sunlight from penetrating into the water. This can have several effects:

1. Reduced light levels can affect photosynthetic organisms in the water, such as algae and phytoplankton, which rely on sunlight to produce energy. This can disrupt the base of the food chain and have knock-on effects on larger marine creatures.

2. The lack of light can also affect the behavior and survival of other marine species. Many marine animals rely on light for navigation, hunting, and mating.

3. The reduction in light can also affect the appearance and visibility of the water, making it harder for rescuers and clean-up crews to assess the full extent of the oil spill and its impact on the marine environment.
