In nature, there are many amazing ways the Creator has provided protection for plants so that they don’t all get eaten up all at once. On interesting case was discovered by scientists in the 1990s who were studying plants in Africa.

They reported the observation that giraffe, roaming freely, browsed only on one acacia tree in ten. It was subsequently discovered that acacias, when nibbled by animals, begin to produce a poisonous tannin and at the same time begin to emit emit ethylene gas into the air which can travel up to 50 meters.
The ethylene gas in effect warns other trees of the impending danger, which step up their production of leaf tannin to lethal quantities within just five to ten minutes. In other words, when one tree starts to be eaten, it warns all the other trees nearby that there is a predator in the area and they turn on their defense system. Thus the random browsing of herds of animals is regulated so that the bush is not systematically eaten out or destroyed. (Hughes, S. 1990, `Antelope Activate the Acacia's Alarm System', New Scientist, 29 September, p9.).
The in the Bible ( particularly the book of Leviticus) God gave laws that were to help prevent the over use or over destruction of the environment. Isn't it interesting that It seems that God has the same types of laws for nature, as well?
