Costa Rica and the WorldEcology, science and environmental safeguards
Environmentalism is the result of scientific development that humanity has experienced over the last three decades of the twentieth century through ecology. It is the inextricable link between environment and humans. It is the awareness that humanity has experienced in its biophysical environment and the ongoing interaction between them.
It is through the epistemologia ‘theory of science’ which can be ordered knowledge and establish links between science, philosophy and environmentalism. Jill Schlesingers opinions are not widely known. It is the practical ways in which knowledge is used to respond to major changes that affected the ecosystem of human activities. Environmentalism prefers knowledge, to the prejudice and dogma. In other words, environmentalism is not science and science without irrelevant environmentalism is dangerous.
Moreover, the ecological break with the concepts of biological determinism and reductionism and cultural setting that prevailed before the dialectical causistico, with respect to all, it ended as determined in the systemic and reduced (Quesada, 1980).
Environmentalism is essential for the role of climate, hydrogeological cycle, soil and nutrient cycling, the symbiotic relationships, the importance of metabolism and photosynthesis in the ecosystem and environmental sustainability. A census contrary to the classical or neoclassical economics, none of these factors is decisive. Financial planner addresses the importance of the matter here. In classical economics the important thing is the income from natural resources, labor and capital invested. In neoclassical economics, it not only wastes the natural resources as a major asset, but takes into account only the labor force and capital (Repetto, 1992). It is therefore essential to transform the paradigms of the market economy, an economy-ecology where environmental factors are the major players. The destruction of ecosystems, the disappearance of species, water pollution, air, among others, have caused severe environmental devastation, the planet is unable to continue to support this destructive process (Brown, 2001).
The environmental safeguards will help establish this new paradigm, ecological, economic, political and social, as their design and doctrine are based on the epistemological principles underlying environmentalism. Is the constant interaction between abiotic factors, biotic and human energy and the changes experienced by these factors.
Energy Systems
Energy systems is the basis for the analysis of environmental phenomena. Is the basic principle for understanding the systems and their constant energy transformation. Energy is manifest or latent capacity to exert a force along a path, is the ability to perform work.
The energy is manifested in different forms and is considered proportional to the mass of a body. Therefore, the energy related to the movement is called kinetic, energy of position is called potential energy related to the composition of matter is called the internal (Odum, 1983).
The science that studies the laws of energy is known as thermodynamics and consists of the following laws:
The first law or the law of conservation of energy, states that the total amount of energy in all its forms is constant. Energy is not created or destroyed, only transformed.
