00:00 00:22 Isolated in the confines of the world, is Patagonia, pampas and forest, mountain and sea with its extreme climate… In this geography coexist two realities.
00:22 00:43 And the natural environment, unique ecosystem of the Patagonian pampa. An environment rich in insects, plant and tree species, bird species of mammals. Establishing a unique and balanced trophic relationships. It is here where the Patagonian man develops its existence.
00:44 01:08 Of the settler, Patagonian man, must conquer this hostile environment, fighting against the elements. It manages to adapt to this hostile environment and becomes another inhabitant of the pampa, it brings with it the domestic livestock and their field work. Breeding sheep and cattle, extract wood as energy source and for construction.
01:10 01:42 So far man has developed a multitude of activities in this environment. Sheep farming, animal husbandry, animal breeding. Has generated support for his family for society as a whole, from the colonization, achieving advances in machinery and procedures, however, these activities would not be possible without the participation of the ecosystem.
01:43 02:04 Where there are multiple species than in his act, in their surviving van controlling the trophic chains and controlling the number of individuals between populations of different species. In addition, marks functions as recyclers of the system consuming carrion and dead animals.
02:04 02:49 However, the man has a hostile attitude toward the medium that contains it and supports it. He attacks it and destroy it… Game over, taking some species on the brink of extinction, putting at risk the stability of the ecosystem. Excessive deforestation. Fire and their indiscriminate use, this led to devastating fires leaving the weakened ground.
Leaving an ecosystem degraded, non-sustainable for man, and dominated by species usually known as pests
02:50 03:01 Hence the importance of an ecosystem healthy to survive to have a sustainable development. We must learn to live in harmony with the environment.
