One night during winter, a bear came into the city of Vancouver in Canada. It walked through the streets, found some food in trash bins (垃圾箱) and started eating. In the morning, someone saw the bear and called the police. They came and took the bear back to the mountains. Luckily ( 幸运地), the bear was safe. But what happens in other countries when big animals go into cities?
In Cape Town, South Africa, baboons (狒狒) go into the city when they are hungry. Sometimes they go into houses and take food from fridges! They can scare (惊吓) people. But the city can be dangerous for baboons too.
Sometimes, they die in traffic accidents (交通事故). Human food is very bad for their teeth. It has a lot of sugar. Now, there are baboon monitors (监督员) working in Cape Town. These people return the animals to the countryside.
In Moscow, there are 35,000 wild dogs. They live in parks, old houses, markets and train stations. Many people give them food and water. Some make small houses for the dogs in their gardens. This helps them during winter.
In some cities, you can see birds, insects (昆虫), mice and squirrels (松鼠) every day. But sometimes, bigger animals can be dangerous. We need to stop them from coming into the city without hurting them.
