Hippopotamus Population Rises in a Small Colombian Town
People in a small Colombian town are reporting increased sightings of hippo-potamuses in the area.
The hippopotamus is native to Africa, not South America. But a local population of the animals developed from a private collection brought to Colombia by infamous drug trafficker Pablo Escobar.
At least 80 hippopotamuses are estimated to live around the rural town of Doradal, about 140 kilometres east of Medellin. The town is near Escobar’s former private estate, covering about 2，225 hectares.
In the 1980s, during the height of his power, Escobar kept the hippos on the property in a private zoo, along with other animals such as elephants and giraffes.
Following Escobar’s death in 1993，most of the animals from the zoo were taken to new homes or died. But because the hippos were difficult and costly to transport, they were left in the area.
Conditions in the area are favourable for the hippos. They live in nearby lakes and waterways, enjoy endless feeding on grass and have no natural predators.
One of the first hippo sightings in Doradal came in 2018. Since then, the animals have continued coming. Officials are worried that they could one day attack members of the local population.
Large hippos can weigh several tons and can be aggressive. The animals kill more people a year in Africa than any other kind of wildlife. Scientists say the presence of hippos in Colombia also threatens the other animals and plant life.
Students who attend a small school behind Escobar’s former property arrive for class each day passing a sign that reads “danger—hippopotamus present”.
So far, the hippos around Doradal have not attacked any humans. But as their numbers grow and they expand into more populated areas, experts fear an attack is more likely.
However, many people enjoy looking at the hippos. The animals have even brought new visitors into the area. Stores throughout the town sell tourist items related to the animals.
A new study by researchers at the University of California, San Diego, UCSD, found that the hippos are changing the quality of the water in which they spend much of their time. The hippos feed at night and then spend the day cooling off in the water, where they release bodily waste.
Scientists have warned that such waste can cause harmful growth and bacteria to develop in lakes in the area. The concerns have led local officials to seek new solutions to the hippopotamus problem.
The local environmental agency responsible for the area, Cornare, is working to find a solution that is acceptable to people in the area, but that will also treat the animals in a humane way.
Gina Serna is a specialist with Cornare. She is helping lead the project. She thinks the hippopotamus situation has become an “urgent” issue.
One plan is to sterilise the hippos. Last year, Serna and a group from Cornare carried out a successful in-the-wild surgical sterilisation of a female hippo, the first ever in Colombia.
Later this year, the group plans to attempt several more sterilisations, as well as a chemical sterilisation method that has proven successful in pigs.
加利福尼亚州大学圣地亚哥分校研究人员的一项新研究发现，河马正在改变它们大 部分时间所处的水体的质量。
The local environmental agency responsible for the area,Cornare,is working to find a solution that is acceptable to people in the area,but that will also treat the animals in a humane way.
此句的主干是： The local environmental agency is working。两个 that引导的是并列的定语从句，修饰先行词a solution。
负责这一地区的当地环境机构Cornare正在努力寻找一个该地区人民可以接受的解决方案，但这也将以人道的方式对待这些动物。
