Dogs are the most popular pets in the world. They make us happier and healthier, but scientists have found that they can also harm the environment in some ways.
One main trouble is dog waste. Unlike wild animals that live on natural food, pet dogs eat processed food, so their waste can pollute soil and water. When left on the ground, dog poop washes into rivers when it rains, spreading something harmful to the environment. In cities, dog waste is one of the top causes of water pollution.
In some natural areas, dogs also cause problems. Studies show that when dogs walk through forests, the number of birds and small animals becomes smaller. The smell and sounds of dogs can make wild animals avoid these areas. Some even leave their babies behind. In countries like Australia, pet dogs have hurt or killed local animals, including rare penguins. This is bad for nature because many plants need these animals to help them grow and spread their seeds.
There are over 700 million pet dogs worldwide, and their large numbers are making things worse. The problem isn't dogs themselves, but how people look after them without thinking about nature.
Since dogs will always be our important family, we need to find ways to enjoy the time with them while also protecting the environment. Simple actions like cleaning up after our pets and keeping them away from special natural areas can make a big difference. Since we share the earth with many other living things, it's our responsibility to keep it safe for everyone.
24. What happens when dogs walk through forests?
A. They help plants spread their seeds.
B. Dogs kill some wild animals for food.
C. Birds and small animals become more active.
D. Wild animals are afraid of dogs and they run away or hide.
25. What is mentioned in the passage about dogs and the environment?
A. Dogs can help protect nature in some ways.
B. Dogs sometimes leave their babies behind in natural areas.
C. Dog waste washes into rivers and pollutes water when it rains.
D. It's hard for dog owners to take action to protect the environment.
26. What is the writer's attitude态度 towards keeping dogs as pets?
A. Strongly disagree. B. Supportive but careful.
C. Not interested. D. Fully agree.
27. In which part of a magazine can you read the passage?
