2d Role play
Interviewer: Jason and Susan, what are your ideas for solving these problems? Jason: Well, to cut down air pollution, we should take the bus or subway instead of driving. Susan: Yeah, or ride a bike. There are other advantages of bike riding. It’s good for health and it doesn’t cost anything! Interviewer: Great ideas! What about waste pollution? Susan: Mmm, I think simple things like bringing a bag to go shopping can help. I started doing that a year ago. Jason: Me, too. Also, I never take wooden chopsticks or plastic forks when I buy takeaway food. I use the ones at home. Susan: And remember to throw rubbish in the bins and keep public places clean and beautiful for everyone. Interview: So together, our actions can make a difference and lead to a better future!
Environmental protection groups around the world, such as WildAid and the WWF, are teaching the public about “finning”. They have even asked governments to develop laws to stop the sale of shark fins. So far, no scientific studies have shown that shark fins are good for health, so why eat them? Help save the sharks!
When people catch sharks, they cut off their fins and throw the shark back into the ocean. This is not only cruel, but also harmful to the environment. Without a fin, a shark can no longer swim and slowly dies. Sharks are at the top of the food chain in the ocean’s ecosystem. If their numbers drop too low, it will bring danger to all ocean life. many believe that sharks can never be endangered because they are the strongest in their food chain. But in fact, around 70 million sharks are caught and traded in this industry every year. The numbers of some kinds of sharks have fallen by over 90 percent in the last 20 to 30 years.
