PETS
Nowadays, animals can be classified into three broad categories:
Wild or non-domesticated, utility or commercial, and pets. Together with the plants, animals, including humans, are very important
to the ecological balance of all life forms. Also, animals and plants,
have supported and contributed to human race’s developing. Wild
animals are very important from environmental point of view and
as reserve for the developing of new pharmaceutical and industrial products. Commercial animals have had a special role in humanity developing because they have worked for us and they have
given food and shelter. Today, Poultry, cattle, and pig livestock, beekeeping and aquaculture are big industries and the mayor source
of food for human society. From the earliest time of humanity,
pets have been our companions, from the affective and the emotional point of view. But pets, now, have a big economic and social importance, and the emotional relationship between pets and
people are much closed, because people are humanizing pets.
