  • Although the main consideration of policy must be the reduction in pollution at source, there has been an increasing recognition that the biosphere is an important sink for many pollutants, with plant canopies being considered more effective than other land uses. Thus, the biosphere provides benefits additional to those associated directly with their aesthetic and wildlife characteristics. Plants facilitate the uptake, transport and assimilation or decomposition of many gaseous and particulate pollutants.

  • Scientific perception of nature relies on a process of transforming data to information, and then information into understanding.

  • In a book titled Photosynthesis it is easy to forget that light is not simply the energy driving plant metabolism. Light also is the central environmental factor that affects plant size, shape and development. In fact, light activation of photomorphogenic signaling pathways sets the stage for photosynthesis and ensures the maintenance of the apparatus. The effects of specific wavebands of light exert their influence on plant biology from the molecular level all the way up to the higher morphological level, and even contribute to the canopy form as a whole.
