SkeptEco #1 – Can organic farming feed the world?

This is the first podcast from Skepteco in which we discuss the scientific basis for organic farming practices and ask the question: if most of the world’s agriculture was converted to organic, would yields be good enough to feed the world?

You can subscribe to the podcasts through itunes. Just search for SkeptEco.

with Eoin O’Callaghan, Naomi Fein, Christina,Michael and Graham.

SkeptEco #2 – Genetically Engineered Food

Genetic Engineering- perhaps one of the most contentious environmental issues of all. For many, the phrase summons up images of “Frankenfoods” and tampering with DNA seems akin to “Playing God”. Certainly, GE crops evokes powerful responses, and is one of the few issues- in common perhaps with some animal rights activism and anti-abortion attacks in the US- that is considered fair game for direct action. In Ireland and the UK at least, activists have repeatedly pulled up field trials of GE crops, and a Europe-wide ban is still in place.

Concerns about GE food crops include the potential for the creation of “superweeds” in the case of Round-up-Ready crops; possible health effects from eating these crops; and a fear of gene-flow from GE crops contaminating wild plants.

Perhaps the main objection however is a deep and pervasive distrust of the big companies like Monsanto who have developed these crops: is it just for profit? Or do their claims that GE crops could help feed the world’s growing population, and help reduce pesticide and fertiliser use, stand up to scientific scrutiny?

In this podcast the SkeptEco team explain what GE actually is, how it is currently being used, and review the current scientific literature for health, environmental and sustainability issues.

  1. Listening to 2nd podcast …
    Wow, professional & sane. I’ll have to stop praising as it sounds like I’m stalking. But really Richard Black’s position might be vacant soon & you guys could take over.
