This news is about leopards in Russia. There are not many leopards in nature today. This is thanks to human activity. Now people want to have more leopards in nature again. They put three Persian leopards in nature.
These three leopards are from a center for leopards in Sochi National Park. People trained them to survive in nature. People want to monitor them and help them if necessary.
Difficult words: survive (not to die), monitor (watch closely), if necessary (if needed).
