this article investigates all spheres, where people exploit animals (food, clothes, vivisection, entertainment) 1. General Ethics 98% of the total biomass -people and livestock, so there are less than 1% of predators. 65 billion animals and about 100 billion fish are killed every year by people only to eat meat. But predators kill according to need and instinct, and we kill unnecessary without need, create more deaths than necessary.Also predators do this because they can not reassure, they can not make another choice. For me, this nature, where one animal kills another is impossibly cruel too, but what people do with animals is worse than that.Popular paintings of chickens and cows walking through the meadow and pigs swarming in the spacious puddles -this picture of the life of life does not reflect reality. The reality is that the life of these animals is filled with suffering, fear and stress, lack of space, the inability to move around, the lack of communication with relatives, the lack of fresh air and sunlight. Now from birth to death each meat-eater in developed countries eats about 3000 terrestrial and 3 thousand aquatic animals. In tables 1 and 2 is presented some data about the exploration of fish and animals to meet our demands [1,2].
