The productive ecosystems in the world total an estimated 50 billion hectare, excluding the icecaps. Marine ecosystems occupy approximately 36.5 billion hectare while the terrestrial ecosystems occupy approximately 13.5 billion hectare. Gross primary productivity for the marine ecosystem is estimated to be about 1 t/ha/yr, making the total biomass production about 36.5 billion metric tons or 145×1015 kcal/yr. In contrast, the terrestrial ecosystem produces about 3 t/ha/yr, making the total biomass about 40.5 billion tons or 162×1015 kcal/yr. The total biomass produced is approximately 77 billion tons or about 12.8 t per person per year.

Britain-science for all by Peter J. Bowler

Historians such as Bernard Lightman, James Secord, and Aileen Fyfe have shown us how the development of Victorian science was shaped by the interaction between working scientists and the general public. Darwinians such as T. H. Huxley openly competed with the advocates of natural theology for the attention of the reading public. Lectures, entertainments, and exhibitions played a role in shaping the careers of many scientists and would-be scientists. Yet we know surprisingly little about the situation after 1900, apart from the influence of a few bestselling scientist-authors such as Arthur Eddington and Julian Huxley, and the efforts of left-wing scientists to raise public awareness of how science was being exploited. We do know something about the development of popular science writing in early twentieth-century America and in some continental European countries. But for Britain we have only a few case studies by Peter Broks, Anna-K. Mayer, and Sophie Forgan. A broader study will allow us to address important issues about how the relationship between scientists and the public has changed between the Victorian era and the present. The early twentieth century was a period in which there were major developments within both the publishing industry and the scientific community.
