One of the biggest problems is plastic pollution in the ocean. Whales sometimes mistake plastic bags for food like jellyfish. When they eat plastic, it can block their stomachs and make them sick or even cause death. Another threat is noise pollution from ships. Whales use sound to communicate, find food, and navigate. Loud ship noises can confuse them and make it hard for them to hear each other. Climate change is also affecting whales. It changes ocean temperatures and currents, which affects the availability of their food. Many countries now have laws to protect whales, but international cooperation is needed to truly save these magnificent creatures.be in danger, take action, run out of, cut down, care about, throw away, clean up, belong to, take part in, find out 1.

B Trees are often called the“lungs of the Earth” for a good reason. Through the process of photosynthesis, they take in carbon dioxide and release oxygen, which is essential for most life on our planet. But trees do much more than that. Their roots hold soil in place, preventing erosion. They provide homes and food for countless birds, insects, and other animals. Trees also help to cool the air and provide shade. In cities, trees can reduce noise pollution and make the air cleaner. Sadly, forests are being cleared at an alarming rate for agriculture, logging, and urban development. This not only threatens wildlife but also contributes to climate change. Planting trees is one of the simplest and most effective ways to help our environment.

First,we should protect their natural habitats. This means we need to stop cutting down forests and polluting rivers. We can support national parks and nature reserves where animals can live safely. Second, we must not buy products made from endangered animals, like ivory or fur. If no one buys these things, hunters will have no reason to kill the animals. Third,we can learn more about endangered animals and tell others about their situation. Knowledge is power. Finally, we can donate money or volunteer for organizations that work to protect wildlife. Every small action counts.If we all work together, we can make sure these amazing animals are still here for future generations to see. 学科网（北京）股份有限公司 $
