Caffeine Is A Natural Pesticide

by Englishclub

Caffeine wakes us up and helps us stay alert. Many
people rely on a caffeine kick a few times a day. In fact,
coffee and tea are the most popular beverages in the
world, making caffeine the most popular drug. Caffeine is
found in the seeds, leaves, and fruit of certain plants.
Have you ever wondered why caffeine exists in coffee
seeds and tea leaves? Studies have shown that caffeine is
a natural pesticide. It gives off a bitter odour to ward off or
kill insects that come to feed on it. While caffeine is
generally safe for humans, it can be toxic to pets and
should be kept away from cats, dogs, and birds.
