«The Final Appeal to Mankind» by Nicolai Levashov

            noi — is the optimum quantity of plants of each species (j) on a unit of surface satisfying
            the requirements for ecological balance.

            njo — is the quantity of vegetable species growing upon a unit of surface.


            Part of the vegetative biomass is consumed by herbivorous animals. The biomass of
            herbivorous  animals  is  accordingly  synthesized  out  of  this  fraction,  following  its
            digestion and metabolism.

            where:

            M p(t) — is the biomass of carnivorous animals synthesized per unit of time upon a
               cg
            unit of surface.


            χcg —  is the BEF  of animals showing which fraction  of the consumed biomass  of
            herbivorous animals becomes transformed into the biomass of carnivores (c) of each
            carnivorous species (g).

            χcg — is the number of carnivorous organisms (c) of a given species (g) dwelling upon
            a unit of surface.

            It should be noted that:


            0 < с < nсо
            0< g <nog

            where:

            nсо — is the optimum density of carnivorous animals of each species (g) dwelling upon
            a unit of surface satisfying the requirements of ecological balance.


            nog — is the optimum density of carnivorous species dwelling upon a unit of surface
            satisfying the requirements of ecological balance.

            Drawing on the mathematical symbols introduced earlier (1), (2), (3) we will now be
            able to represent the mathematical model of the resulting ecological system:

            M p(t) + M    ab p(t) + M p(t) = const.  (4)
               ij
                                     cg
            After the substitution of the values of items into equation (4) we obtain:

                                   s a b                               s a b                s a b
               ij
            M p(t) {1+ ∫ ∫ ∫ χab nab dsdadb + ∫ ∫ ∫ χab nab [ ∫ ∫ ∫ χcg ncg dsdcdg ] dsdadb=const.   (5)
