B(2025·绍兴嵊州市期末)
Wolves may seem scary, but they could help save Scotland’s forests! A new study shows that bringing wolves back can make the forests healthy. Why? Because wolves can help trees grow, and trees are really important. They take in carbon dioxide(二氧化碳), a gas that makes the world warmer.
In the UK today, there are no wild wolves. Over 250 years ago, people killed all the wolves in Scotland. Because there are no wolves, red deer have no natural enemies(天敌), so their numbers became very large. Red deer love to eat young trees, and this stops forests from growing. Now, only 4% of Scotland has forests, much less than in many other countries.
Scientists used a computer to see what would happen if wolves came back. They found that 167 wolves could control(控制) the number of red deer. Then, more trees could grow and take in more carbon dioxide each year!
Some people might not like this idea. Farmers are worried that wolves will make their cows and sheep in danger. But the scientists want to share this new information. They hope people will see the good things wolves can do for nature.
