主题：The decrease of Chinook salmon in Alaska

1. Competition for Food

One possibility is that another salmon species-pink salmon—is outcompeting Chinook salmon for food. In Alaska, populations of pink salmon have been increasing. As pink and Chinook salmon feed on some of the same types of prey, such as small fish and squid, the larger population numbers of pink salmon give them an advantage over Chinook salmon when hunting for food. As a result, there is not enough food left for Chinook salmon to survive on.

1. First, the competition with pink. Yes, paint and chinook salmon eats some of the same play. But they don't look for prey in the same places. Let me explain. Chinook salmon tend to hunt in areas of the ocean closer to land, while pinks and hunting areas farther away from land. Also, should the nook salmon look for food deep below the ocean's surface? While pink salmon stay near the stitches. The fact that chinook salmon and pink salmon hunts from brain in different areas of the ocean means they don't have to compete for food.

2. Warm Ocean Temperatures

Another theory is that warm ocean temperatures caused the decline of Chinook salmon. Biologists noticed a significant decrease in the Chinook salmon numbers after a mass of unusually warm water called "the blob" appeared along the coast of Alaska in 2013. Chinook salmon are cold-water fish, and warm ocean temperatures negatively affect their health. When temperatures are higher than usual, it takes more energy for Chinook salmon to swim, which stresses their bodies, especially their hearts, and threatens their survival.

2. The warm temperature explanation is also problematic. You see, when the glob, that mass of warm water you read about appeared. Salmon had already been in decline for quite a while. In fact, chinook salmon had been declining for over a decade was working. Besides. In the last seven years ocean, temperatures have returned back to normal cooler conditions. Yet despite these, cooler coastal waters should examine, are still declining. Certainly the warm blob hurt the salmon population, but the decline was observed both before and after. So clearly there must be some of the.

3. Predators

A final explanation is that predators, such as sharks, are responsible for the decline of Chinook salmon. In one study, scientists attached satellite tags to a number of wild Chinook salmon in Alaska. Satellite tags are small devices that send out radio signals about the animals' locations and the surrounding environment. Data from the tags attached to Chinook salmon showed that the majority of the salmon ended up being eaten by sharks and other predators.

3. Finally, the creditors. Remember the satellite tags that scientists attach to the salmon in the study? Research has shown that these tags make it more difficult for salmon to swim. When tags are attached to salmon's bodies. Their swimming speed is reduced. Also, seaweed and other sea organisms make room on the tacks, and that further slows down salmon and prevents them from swimming fast enough to avoid predators. So it's probably the tags used in the study that made the salmon more vulnerable to being eaten by recorders. They have provided the tax do not mean a whole population of chinook salmon is threatened by predators

学术讨论

　　Your professor is teaching a class on sociology. Write a post responding to the professor’s question.

　　In your response, you should

　　· express and support your personal opinion

　　· make a contribution to the discussion in your own words

　　An effective response will contain at least 100 words. You have ten minutes to write.

　　Doctor Achebe:In today's world, we have various ways to stay informed about current events. Traditional sources like television and newspapers have long been trusted by many, providing detailed and well-researched news. However, with the rise of social media, an increasing number of people are turning to these platforms for quick and accessible updates. Which do you think is a better source of news: traditional outlets like television and newspapers, or social media?

　　Kelly: I believe social media is a better source of news because it provides quick updates. For example, during breaking news events, social media platforms often deliver information faster than traditional outlets like newspapers or television. This immediate access allows people to stay informed in real-time.

　　Paul: I think traditional news sources are better because they tend to be more accurate. Television, for instance, not only provides well-researched reports but also offers visuals that help viewers understand the story better. Social media might be faster, but it often lacks the depth and verification traditional sources provide.

　　范文：

　　I prefer getting news from traditional sources, such as television and newspapers, primarily because they provide reliable information and in-depth analysis. Unlike social media platforms, where anyone can post without fact-checking, traditional media rely on professional journalists and experienced editors to ensure the accuracy of their reports. This process gives me confidence in the news I consume and helps me gain a full understanding of the events. For example, after the Wenchuan earthquake in China, numerous users on social media spread false stories and edited photos, causing public panic. However, professional journalists, who traveled with the rescue teams, provided clear and accurate reports, reassuring people that the government was actively responding, and thousands of lives were being saved. This stark contrast demonstrates how traditional media play a crucial role in providing trustworthy news during crises. In conclusion, traditional media, with their professional standards, offer a more reliable source of information than social platforms.
