ESSAY TITLE: The evolution and the Nature degradation Since the beginning of times, every creature has been part of Nature and produced useful trash, which has been the basis of the future generations. The environment or biosphere is a system that includes every being in our planet, as air, water and soil constitutes their habitat: the place where the vital cycle takes place. Each biological process begins with solar energy, the real source of life on earth. Green plant use solar power for photosynthesis, turning inner matter into organic substance and releasing oxygen. In early times, man’s nourishment was just related to soft and juicy food, like fruits, roots, insects and scarcely meat. During this period, man’s action upon the biosphere was minimum, limiting the use of fire to certain ecosystems to push animals outside the forests and therefore get an easy hunting. The step from primitive community to the first shepherds and agriculture civilisations derived from the
division of
work and the first social class division, bringing about the disturbance on the environment. To cut down and burn was the basic crop way that allowed man to be free from their millennial dependency on hunting and the picking of fruits and roots. At the same time, the abusive practice of vegetables destruction carried out deep
climate changes in many parts of the Earth; turning wide lands into sabanas ,arid and poor soils and even deserts. With these actions, man began to
change the sacred balance of Nature. The looting of Nature The next step to more developed ways of productions involved the availability of more effective technical means, and that matched with an increment in the population. All along Middle Ages, the abusive forest depredation to ease agriculture and cattle raising kept on, and wood became a commonly used product. With the European
geographic expansion and its powerful means of destruction, the “wild nature” was just a simple enemy to defeat, and its natural resources, because of its abundance, were supposed inexhaustible. The
Industrial Revolution At the end of the XVIII century the new social and economic productive conditions determined major scientific breakthroughs. Until 1800, all the energy available was supplied by food metabolism and biological oxidization from those compounds that storaged solar energy. With the Industrial Revolution new machinery tools were introduced in the productive process, which needed solid fuel as power source and, with its combustion, brought with it a gradual increment in nocive effects. The
urban explosion The historical process of urbanisation that took place as a consequence of the agriculture labour surplus did not represent a major influence on the environment. But the Industrial Revolution starts the emigration to cities, promoted in order to elevate the working forces rates, essential to the industrial development. These are the conditions that determined, along with the recession of natural systems, the growing environmental pollution derived from the abuse in the energy expenses, the multiplication in the material volume and density, and illogical space organisation, without respecting the ecological lows of a healthy human society. The future Whether the evolution has been planned by an Upper Intelligence or is just a simple chain of natural facts, it does not matter. There seems to be no point in trying to stop the human development. Our only hope may reside in the Indian said: “ When the last tree has fallen the last river dries up and the last fish has been eaten men will realise that they cannot eat the money.”
