Figures were published in yesterday's Telegraph which indicated that
2.5% of current carbon dioxide emissions worldwide are caused by human
activities. 97.5% therefore originate from other sources, presumably
natural, such as the exhalations of animals, emissions from trees and
plants, natural decomposition and fermentation processes, etc. How do
the environmentalists propose to reduce this?

The crucial point here is NET emissions. The biosphere emits 102 Gt of CO2
per year but also takes in the same quantity by photosynthesis. The 5 Gt
produced by burning of fossil fuels is just addition.
