 Elegant Description of Environmentalism

Man has generally been preoccupied with obtaining as much 'production' from the landscape as possible, by developing and maintaining early successional types of ecosystems, usually monocultures. But, of course, man does not live by food and fiber alone; he also needs a balanced CO2-O2 atmosphere, the climactic buffer provided by oceans and masses of vegetation, and clean (that is, unproductive) water for cultural and industrial uses. Many essential life-cycle resources, not to mention recreat...

We need more than production from the land, we need a clean environment because we live in that same land.

The authors comment that from this perspective, it could be stated that multiccellular beings are also ecosystems. That is, we are formed by different types of cells that cooperate and compete for resources; we are colonized by diverse types of bacteria (in the intestines, in the skin, etc.) whose activity is linked to other processes in our organism: we are invaded by viruses, which can be harmful or can take part in processes that regulate our DNA. "These beings are constantly being changed...

 Microscopic and Macroscopic Perspectives in Science

In science, simultaneous macroscopic and microscopic exploration is quite customary, especially in biology. Molecular biology, for example, which derived from the application of chemical analysis to biological problems and led to the discovery of DNA and its function as the carrier of information for every form of life, has developed independently from physiology, which concerns the whole animal and the way it functions as an integrated living system. In like manner, the difference between th...
