Daily tasks Gather the elephants at 6：30 am. Take them to look for food in the forest. Clean the enclosure (围场).Swim with the elephants in the lake in the afternoon. If volunteers want to relax after work, they can watch satellite television. How this vacation helps If these elephants hadn't been rescued, they would still be living on the streets of Bangkok. The rural environment is much better for them than the urban environment where there is lots of pollution.

Extra activities include dog sledding and a night trip to see the Northern Lights. How this vacation helps If the Arctic ice cap melts due to global war
