A living being is a organism of high complexity that is born, grows, reaches the capacity to reproduce and dies . These organisms are formed by a large amount of atoms and of molecules which constitute a system endowed with organization and in constant relationship with the environment.
Living beings can function autonomously throughout their existence and just suffer the loss of their structural properties at death. These beings are formed by cells , within which various chemical reactions take place that enzymes are responsible for catalyzing.
There are several characteristics that allow us to differentiate a living being from what is subjected to inertia. The organization (from the cells, which are its primary entities), the homeostasis (the balance that exists inside), the metabolism (the conversion of energy into nutrients), the irritability (response to external stimuli), the adaptation (living species evolve to adapt to the environment), the developing (increase in size) and the reproduction (The ability to generate similar copies of the same organism, either sexually or asexually) are some of the properties of living things.
Other types of entities share several of these peculiarities, but not all. The virus They also have a high degree of organization and can reproduce, although they do not have metabolism or develop.
The most typical examples of living things are the Humans , the animals (of all kinds: dogs, lions, elephants, dolphins, mosquitoes, snakes, etc.). and the plants . There are, however, other living organisms, such as mushrooms and the bacteria .
The different cultures created by human beings share the unfortunate tendency to harm other living beings, always looking justify your actions so as not to face his cruel and ruthless condition. The perhaps most innocent way in which people attempt against nature is the killing of animals for their own food; the different species that serve as a snack for the insatiable digestive system of men are raised in conditions that little could envy the victims of wars and concentration camps, deprived of their freedom and condemned to gain weight for later be killed.
It is sad to think that his only consolation may be the fact of living five times less than expected, at best, as many go through the blade shortly after birth, like calves. Human beings grow up as indirect participants in this horror, and some take the next step and become executioners. The most terrible and worrying thing is that we shield ourselves in ridiculous and inaccurate reasons, where the word protein is usually the protagonist.
But animals are not the only victims of our species, since the vegetables we eat do not enjoy a lifetime very natural. As usually happens, there are groups of people who try to promote change, end so much violence and begin to live in harmony with the other inhabitants of this planet; But the structure of human societies is not compatible with respect and equality.
Dogs are the closest example that many people have of living things that learn to adapt and respect those around you. Starting from the fidelity and affection they show us, they accept all kinds of impositions and humiliations, such as training processes, in order to make us happy. They support rides where they are not allowed to run in freedom, which should be tortuous for such active animals. They submit to all these unfair conditions and never use their superior strength or their Super senses or of its claws and teeth to be imposed; If only we began to imitate them, we would solve a large part of the world's problems.
