Reindeer help Santa Claus to deliver presents to children. However, the animals are in danger. Many reindeer are being killed by wolves. Reindeer owners say wolves killed 1,950 reindeer in Finland this year. That is a 70% increase from last year. This increase has upset the natural balance between reindeer and wolves.

A reindeer owner joked about his animals, but he is worried. He said: "These are Santa's reindeer. We are really lucky because Santa needs them for one day, so we can fly them for 364 days." Many people believe the Ukraine War is why there are more wolves. Many wolf hunters in Russia have gone to fight in Ukraine.
