One of the many interesting things about the JWs is this (from Wikipedia):
Jehovah's Witnesses distinctly believe that only 144,000 people will be raised to heaven, and will thus spend eternity with God. They do not believe that this number necessarily comes from descendants of Jacob, but from early Christians, and those of Jehovah's Witnesses who profess to be "anointed" (or "spiritual Israel"). Witnesses believe that the 144,000 have been selected by God from the time of Jesus' apostles through to today. They believe that the 144,000 (those having a "heavenly hope") will reign with Christ in heaven, while all other people accepted by God will live forever on a paradise earth (an "earthly hope").
The illustration must depict the "Paradise on Earth." It seems nice with racial unity and all, but people don't seem to be mixing. And it seems weird that the predator prey relationship has been suspended in the after life, but judging from the leaves, Fall is on the way, so they will still have to deal with winter.
