[动物保护]The tequila fish is a kind of small freshwater fish that lives in the rivers and lakes of the southwest of Mexico. This kind of fish could be easily found in Mexico many years ago. Unluckily, it disappeared over 20 years ago.
However, a team had a great try. With the help of workers at Chester Zoo in England, scientists in Mexico have changed this situation—they raised the tequila fish first and put captive-bred(人工繁殖的) fish back to the wild when they grew up. The team has now made sure that the fish are producing eggs and that the population is increasing in the wild.

The good news is that the tequila fish is slowly coming back into the local river system. They think of that as a very good start and hope that more kinds of animals could have the chance to be alive.
It’s reported that one million kinds of animals are in danger around the world. So here in Mexico, what they did to the tequila fish is a sign that with people’s help, nature can make a comeback. For example, ▲ Many people believe that humans will get on with nature well.
