    The relationships between plant groups are still being worked out, and the names given to them vary considerably. The clade Viridiplantae encompasses a group of organisms that have cellulose in their cell walls, possess chlorophylls a and b and have plastids bound by only two membranes that are capable of photosynthesis and of storing starch.

    Solow [4] showed that, given a degree of substitutability between human capital and natural capital, one way to design a sustainable consumption program for an economy is to accumulate man-made capital. When this accumulation is sufficiently rapid the effect from the shrinking exhaustible resource stock is countered by the services from the ...
