THE ENVIRONMENT

INTRODUCTION The environment is everything that surrounds us and that we must take care to keep our city clean, school, home, etc.. Finally we can be all in, so we have made the following Environmental investigation.

-OBJECTIVE GENERAL To contribute to the preservation of the environment, strengthening the culture of recycling, caring for watersheds and the use of natural resources through the use of techniques for transforming the role, undertake marketing of recyclable materials and implementing campaigns proper management of wastes, process performed based on the use of computers and telecommunications for consultation, exchange of inputs, processing and sharing of work experience. -SPECIFIC OBJECTIVES *Consult the Internet or with the use of multimedia software, related terms environmental pollution, with processes of care and environmental protection and recycling. *Consult about recycling processes and experiences in different parts of the world through the web, in magazines or other media. *Know and apply the basic principles of environment to foster a sense of belonging to the institution, running ecological actions for the protection and improvement of the environment, creating harmonious half for a peaceful coexistence.

-ENVIROMENTAL CONCEPT Environment, abiotic itemset (solar, soil, water and air) and biotic (living organisms) that make up the thin layer of the Earth called biosphere, livelihood and home living. -COMPONENTS OF ENVIRONMENT. The air, which protects the earth from ultraviolet radiation and excess allows the existence of life is a gaseous mixture of nitrogen, oxygen, hydrogen, carbon dioxide, water vapor, other elements and compounds, and dust particles. Warmed by the sun's radiant energy and THE EARTH, the atmosphere circulates around the planet and modifies the thermal differences. In regard to water, 97% is in the oceans, 2% is ice and the remaining 1% is fresh water from rivers, lakes, groundwater and atmospheric humidity and soil. Soil is the thin mantle of matter that sustains life on Earth. It is the product of the interaction of climate and bedrock or bedrock, as glacial moraines and sedimentary rocks, and vegetation. Of these depend living organisms, including humans. Plants use water, carbon dioxide and to convert sunlight carbohydrate feedstocks through photosynthesis; animal life, in turn, depends on plants in a sequence of links interconnected network known as trophic . During its long history, the Earth has changed slowly. Continental drift (result of plate tectonics) separated land masses, oceans and land invaded withdrew from it, and rose and eroded mountains, depositing sediment along the coast (véaseGeología). Climates flared and cooled, and appeared and disappeared lifestyles changing environment. The latest major environmental events in Earth's history occurred in the Quaternary, during the Pleistocene (between 1.64 million and 10,000 years ago), also called glacial period. The subtropical climate disappeared and changed the face of the northern hemisphere. Large ice sheets advanced and retreated four times in North America and three in Europe, swinging the cold to temperate climate, influencing plant and animal life and, ultimately, leading to the climate we know today. Our was received, either the names of recent postglacial and Holocene. During this time the global environment has remained more or less stable. -ENVIROMENTAL PROBLEMS The species Homo sapiens, ie human beings, appeared late in the history of the Earth, but has been able to modify the environment with their activities. Although, apparently, humans made their appearance in Africa, soon spread throughout the world. Thanks to its unique mental and physical abilities, managed to escape the environmental constraints that limit other species and alter the environment to suit their needs. Although certainly the first humans lived more or less in harmony with the environment, like other animals, their distance from wildlife began in prehistoric times, with the first agricultural revolution. The ability to control and use fire allowed to modify or eliminate the natural vegetation, and the domestication of animals and grazing herbivores led to overgrazing and soil erosion. Growing plants also resulted in the destruction of natural vegetation to make room for crops and fuelwood demand led to the denudation of mountains and depletion of entire forests. Wild animals were hunted for their meat and were destroyed in the event of being considered pests or predators. As human populations remained small and modest technology, its impact on the environment was only local. However, as they grow and improving the population and increasing technology appeared most significant and widespread problems. Rapid technological development occurred after the Middle Ages led to the Industrial Revolution, which brought about the discovery, use and exploitation of fossil fuels and the intensive exploitation of the mineral resources of the Earth. It was with the Industrial Revolution when humans began to really change the face of the planet, the nature of its atmosphere and the quality of your water. Today, the unprecedented demand for the rapid human population growth and technological development are subject to producing an environment increasingly rapid decline in its quality and its ability to sustain life.

-CONCLUSIÓN The Environment is the greatest work of the Lord, that is why we care for and preserve it for the good of ourselves and all living beings on our planet. Causes the destruction of the ozone layer, water pollution, carbon dioxide, acidification, soil erosion, chlorinated hydrocarbons and other sources of contamination such as oil spills are destroying our planet, but the "cause which produces other causes "is ourselves ... there are people who do not mind throwing a can in the street or a paper, or anything else, knowing that more and more are polluting the environment, the right thing would be to put the trash or waste in the trash or take it to the nearest trash that is on the street, regarding air pollution drivers should look for ways that your vehicle does not create as much carbon dioxide, which is completely harmful as well as acids used for plants, also insecticides and other chemical sprays, for the ozone layer is very important for us because it protects us from the sun's ultraviolet rays. My message is: Do not throw trash where you should not, keep your environment clean as if it were your own life, because it is.
