    Let's define "valid happiness is the feeling of things being a-step-better for keeping our DNA alive"
    and, the feeling is one of our instincts formed 10,000 years ago by our ancestors from their successful experiences for survival and saved in our DNA.

    Then, the happiness out of the validity scope of our instinct of happiness is the “invalid happiness”.

    We are unable to detect this invalid happiness intuitively
    because we have not bio-evolved to renew our instinct to detect it.

    This invalid happiness is harmful in most cases.
    Such as: taking junk food, drinking alcohol, wearing clothes not for protection,
    ... making too much money to cause greed, inequality, crimes, wars,
    ... “unsustainable” world.

    Obviously, by well-proven common sense, they are:

    (1) Threats ---- Invalid (harmful) happiness,
    which wastes about 90% of our planet resources.
    (2) Solutions ---- Quit the invalid happiness,
    which saves about 90% resources to increase plenty food.

    (from Be Happy Validly)

    • May 30 2013: i agree with you LaMar, industrialization, urbanization and population growth all taking place, on the other hand land is reducing meaning limited food production. do the industrialized countries have enough land for farming? i quote you "When we build towns and cities we need to include areas for farming and food production in those plans..", i stand to be corrected, the developed world has limited land compared to the third world, am i right to say the rural areas and the third world are key to achieving food security?

    May 28 2013: Thanks to Genetic Engeneering we already have coltures in some areas that we would never been expected to have, considering the natural characteristics of some products. Now we're able to plant and cultivate strawberries, wheat, barley, tomatoes and lots of others in extreme terrains in which they would never been growth without improving their genoma. All without any risk for health, despite what we can listen occasionally from some unschooled voices (you know...audience brings money), and with great perspectives for the developing countries and the 3rd Wolrd. Then, if you're asking if we can solve global hunger, the answer is "Yes, but hungry people is easier to control low-cost. That's why many political leaders are refusing to take this promising way. They need global hunger to legitimate their power, to employ low-cost workers, to remain among the rich countries by making them to stay among the poorest ones. "
    From this point of view, we live in a sad and senseless present, so here's another question Njavwa: "How we could change things?"
    • May 30 2013: considering its "global food security" do the low income countries with land in abundance afford the new technologies? and enlighten me on how global hunger is of essence ans we both walk through the path of how we could change things.
