Humanity will be challenged by increasing population growth

Harrison Brown : physicist, geochemist
The future will be determined by the rates of birth and death, speed of nonrenewable resources consumption, rapidity of technological development mostly to solve the problem of resources and food.
A linear scientific approach when all the conclusions and treats which humanity has to face by 2057 has to deal with increasing rate of population growth. Probable solutions consist of both developing technologies in industry and agriculture and eugenics (breeding and death control) that should follow. This approach mostly includes 2D-modelling, 2 factors correlation without understanding the purpose of civilization development.
