Flies is one type of animal that is harmful to human health. flies bring the spread of disease through the food we consume.
However, every living being has the right to trace the right to life, and the living beings also have the right to preserve the offspring, so as not to become extinct.
In this post, I put one example of breeding that is done by animals of flies, they do marriage as happened to other animals. they (flies) breed by mating, or so-called vegetative means. that is by doing the relationship of two types of animals that meet the eggs contained in male flies with ovum cells contained in female flies.
