    January 24, 2011
    Professors Paul and Anne Ehrlich
    Center for Conservation Biology
    Stanford, CA 94505

    With this letter, the Committee for a Sustainable World Population (CSWP) of the Sierra Club Mother Lode Chapter wishes to recognize your courageous and resolute efforts over several decades to relate world overpopulation and world population growth to global environmental problems.

    World population growth increasingly stresses our limited global natural resources, and contributes to the degradation of our air, land, water, and fish and wildlife habitats. Continuing global population growth will inevitably overwhelm any attempts to reduce per capita resource consumption, and to attain environmental sustainability.

    Best wishes for success in your vital population-related programs during 2011!

    Our Mission

    Our goal is to increase awareness of the environmental impacts of population growth and overconsumption of natural resources, and to help improve access to family planning, reproductive health, and sex and environmental education services.

    We offer a speaker's bureau, and we promote population awareness at public events, fairs, and conferences.

    2012: Happy couple, just won a CBD condom on the CSWP roulette wheel

    Is there a relation between religion, sex and the number of babies per woman? In this TED talk from Doha, Qatar, Hans Rosling discusses this delicate topic and explains the main reason why the world population will increase with another 3 billion people.

    It's not religion; it's not income. What is it?
