98. (c): The benthic region includes all the sea floor from the wave-washed ashore-line to the greatest depths. Depending upon the penetration of light it is subdivided into two main zones: the lighted or littoral zone and the deep sea system. Due to abundance of light, water, oxygen, carbon dioxide and less salanity of water, the tidal zone is characterized by exhorbitant growth of plants. The dense growth of vegetation, on the other hand, provides shelter and food for animals. A wide variety of algae, few grasses and animals of every phylum of animal kingdom are represented in this region.

The second point in support of tree plantation pertains to the role of trees in keeping the pollution levels within a city under control. To expand on, the extent to which air pollution has becomes a cause of concern in urban dwellings is highlighted by the ever increasing number of people migrating to countrysides for fresh air. This is an extreme step, I believe, which can easily be avoided, as the natural mechanism within a tree to absorb toxic gases, and to convert them into oxygen presents itself as a feasible alternative remedial measure. Trees can thus be of immense importance in urban landscapes.

In the course of this enquiry I found that much more had been done than I had been aware of, when I first published the Essay. The poverty and misery arising from a too rapid increase of population had been distinctly seen, and the most violent remedies proposed, so long ago as the times of Plato and Aristotle. And of late years the subject has been treated in such a manner by some of the French Economists; occasionally by Montesquieu, and, among our own writers, by Dr. Franklin, Sir James Stewart, Mr. Arthur Young, and Mr. Townsend, as to create a natural surprise that it had not excited more of the public attention.
