Mother did not have the strength to swim back and save her three babies.
The weather is already getting cold, lakes and rivers are freezing and the water is already dangerous, especially for animals. That is why when there are severe frosts, animals must cross over to the opposite shore, and this is very dangerous.
Once a bear with her cubs approached the river. The mother was first and the babies were behind. Soon the current did not allow them to be.
Cute cubs were very difficult to keep afloat. Mother swam to the shore and she no longer had the strength to swim back and save her babies who could drown and die.
Fortunately, there were fishermen on a boat and when they saw this scene they decided to help the cubs.
Mother Bear noticed that a boat with people swam up to the babies and of course got very worried.
The mother immediately began to growl. The fishermen realized that they should not touch bear cubs because bears are very dangerous animals and can attack people when they get close to their babies.
But people decided to put these cubs in the boat because it was impossible to save them in any other way. The fishermen managed to pull the babies out of the water and save their lives. And there was another obstacle ahead.
If people would decide to swim to the shore, then mother bear could attack them. So they decided not to approach the shore, but move along it and quickly released the cubs one by one.
Mother bear immediately followed them, took them, and ran into the forest.
