Dead Animals
Over the last couple of years, many animals have died off in large numbers.
According to Hosea this is nothing new of course:
Therefore shall the land mourn, and every one that dwelleth therein shall languish, with the beasts of the field, and with the fowls of heaven; yea, the fishes of the sea also shall be taken away.
- Hosea 4:3 (KJV)
