    If you live in Shanghai, you might have taken a "lesson" in sorting(分类)garbage, as the city introduced new garbage-sorting regulations(规章)on July 1, 2019.

As China' s first city to carry out strict regulations on garbage sorting and recycling, Shanghai requires its residents(居民) to sort garbage into four categories(类别), namely recyclable, harmful, dry and wet waste. If people fail to sort their garbage properly, they can be fined up to 200 yuan.

Since the regulation took effect, the amount of total daily waste in Shanghai has been reduced by an average of 15, 500 tons, dropping 26 percent from the end of 2018, while the average daily weight of recyclables hits 4, 500 tons, five times higher than the end of 2018, according to the Shanghai Landscaping and City Appearance Administrative Bureau.

The city also rebuilt 21, 000 waste-sorting stations and more than 40, 000 waste bins have been dated(更新). The city's waste collection and transportation system is complete, according to the bureau.

"Proper waste sorting protects the environment and saves natural resources, " said Deng Jianping, director of the bureau. "Led by the central government, Shanghai is making efforts to develop long-term solutions to garbage management. "

However, there have also been some problems. Some people complained that it is difficult to deal with wet garbage, as they are asked to remove wet garbage from its bag when dumping(倾倒).

According to the sorting rules, the wet garbage must go in the wet waste bin and the bag must go in the dry waste bin.

This separation is necessary, as it ensures that the wet garbage will decompose(分解)properly and become useful organic(有机的)waste, the bureau said.

Plastic bags can affect this process. Some people in Shanghai are instead using paper bags that can biodegrade(生物降解)or plastic containers that can be washed and reused, according to Xinhua.

    Amy is a biologist(生物学家)working at a marine(海洋的) park. These kinds of parks provide fun and education for tens of thousands of people each year.

Amy takes care of many animals in the park, but she also does important research. As she observes the animals that she looks after, she learns more about their needs and behavior. This information helps the animals in the park, but it can also be used to protect other members of the species in the wild.

It's hard work to look after these animals. Their needs often change according to different hours of the day. So Amy must depend on her science knowledge and good number sense to help her make the right decisions all day long.

Even though dolphins spend much of their time underwater, they are mammals(哺乳动物). This means that they must come to the surface to take in air. Dolphins give birth to their young. They're not hatched from eggs. Just like all other mammals, mother dolphins must nurse, or feed milk to their babies.

Amy and her team know this first-hand. One of their dolphins recently gave birth. A baby dolphin is not small, either. It was almost 1 meter long the day it was born. A big dolphin usually eats about 4% of its body weight in food every day. Amy knows that a mother dolphin that is nursing needs twice the food. So when the baby dolphin was born, Amy immediately doubled the mother's food every day.
