    #14 @Devesh Bhatt thanks for taking the time to reply and for the very informative perspective. I agree "we have to do better at truly understanding the present set of circumstances associated with this and related issues (Food, Energy, Water, Population) with an eye towards the collective future of mankind and our earth." The sad thing is that in many respects we have been watching the scientific and economic yin and yangism on the subject since 1896 when Svante Arrhenius, a Swedish scientist was the first to claim that fossil fuel combustion may eventually result in enhanced global warming.

    To me it is not an East thing. It is not a West thing, It is not a young thing. It is not an old thing. What it is, is a ONE EARTH thing. It is a journey to enlightenment and understanding before it is too late. Thank you again and all the best to you. Keep making a difference; one person, one step, one generation, one tree, and one river at a time.

    #11 @Todd Jones Thank your for the comment and thoughts. Wouldn't it be nice if we all could just think differently about our ONE little EARTH? Awhile back I was in a discussion on a different social media blog site. The discussion was on population and I had made a comment about the fact that ours was increasing and would hit the 9+Billion mark on or before 2050. I received a scathing rebuke by this individual that statistically speaking the world population was actually decreasing. After wading through semantics and other nuances, a couple well intended arguments I merely responded with the following: "OK, so help me with the math here. If the world population is currently at 7+Billion and will be at 9+Billion in about 30 years, I will give it to you, statistically that may reflect a potential decline in the rate of increase? In the end though, doesn't that decline still show and increase albeit at a decreasing rate? Never got a response back To me, in the end I just want to get past the yin and yang of it all and do things differently. Keep making and difference; one person, one step, one dare at a time. I Dare You to embrace a different mentality about ONE EARTH as it is the only one we have.

    en we show corporate backed experiments of greening wastelands.

    It all boils down to proper land use, which is 0 here, I still think that residents and people born at a place have affinity with local ecology, mass migration to cities leaves the rest of the country at the mercy of rampant exploitation and one city near a river bank can be more harmful than a 1000 villages just consuming and dirtying everything around...But that is the definition of progress.

    Ancient cities survived at river banks and were surrounded by forests, in their new form they are not fit to be at the riverside, rather use that land for forests and agriculture, and build a conservation model centred on trees, they clean air water soil and sustain wildlife.
    Environment + economics + local sustenance, it is possible but the way you are considerate for the coming generations, that is no priority of the young here, not the farmers son, not the local village chap, nature seems like old world to them and they would sell it any chance they get.
    If only we secured critical ecosystems while we Heal the cities.

    I am from a populated country , India. I was born in the Himalayas, people here want mother nature to survive and thrive as it is.

    While the world is being told about air pollution and receding glaciers etc , what I feel is this. The per capita consumption of this area is very low, our population pressure is also very low and the people have more or less taken care of their energy needs from.renewable sources.

    Still the problem persists ...Why? People from the city are grabbing land, encroaching on forest land and cutting trees, making summer homes and resorts that have less than 50 days of occupancy... What they actually hurt is the underground springs, the strength of the hillside which earlier came down as soil but now comes down as rock.

    Population control, reduction etc are a huge loop, despite all the planning, it's results would be evident after a few decades, what is a must right now is that populous nations do not ape the West blindly cause we suck at waste management and we have outright ditched traditional practices rather than filtering out local conservation practices which are community driven, cheap and sustainable.
    Now if I talk about Delhi region, same problem, 60 million flats under construction next to the Yamuna river bank with less than 10℅ occupancy, rampant deforestation and agri land misuse. Contd

    Great post Joel.

    On the issues of water, food, energy, and population, it is population that drives scarcity of the other three resources and hence the most important element of this discussion. Research suggests that the planet broke the billion person mark sometime around 1800. It took 125 years to add another billion people. Then 33 years to add a third billion. We now stand at over seven billion, and are adding an additional billion people to the planet every 15 years or so. It is simply not sustainable.

    Thanks for re-upping this with a link on the other site, @Joel Anderson. I have to simply make one tiny change..."complementary nature of opposites that may just be interconnected"

    It is all interconnected. Every single bee - each literal and metaphorical bee - has a part to play in each of these global environmental topics because we are all contextualized within the planet Earth's ecosphere.

    But here is the rub, as you rightly mention we are dependent on corporations to a tremendous extent to wake up and smell the humanity not the profits, but we've let them be exempt from concerns apart from increasing shareholder value EVERY 90 DAYS. Until we begin to challenge this concentration of financial and human capital within organizations more powerful than most governments, we are not going to stand a chance towards collaborating towards a sustainable future for the entire planet.

    Capitalism is swell to a certain extent, but when it creates entities that can decide to take over the world's seeds, or introduce endocrine disrupting plastics into baby bottles to increase profits, or bottle up the liquid elixir of life and in the process generate waste that will last for decades we have to ask when will we wise up and ask for these organizations to have oversight ensuring that they don't jeopardize the planets future? That has to be the definition of 'good' business.

    #2 Hi Ken, it seems that straw bale building is taking off in SA at long last. In fact the largest straw bale building in the world is the Didmala Lodge in Limpopo - see links below. http://inhabitat.com/five-star-didimala-lodge-is-the-world%E2%80%99s-largest-strawbale-building/worlds-largest-strawbale-bldg-1/

    This is most interesting, Claire Caldwell. I didn't know there were so many benefits to building with straw. I thought the flammability would be an issue but perhaps if it is densely baled, then it's possibility is reduced.

    #5 Thanks for tagging me @Ken Boddie. Natural materials and building techniques are one of my favourite subjects regarding civil engineering. There are many research papers on straw bale published by large standards organizations like ASTM, as well as many academic journal papers. In US and Canada, as far as I know, the Straw Bale Construction Building Codes have been adopted in 2013. Thanks for interesting article @Claire Cardwell.

    #7 Thanks, Ken @Ken Boddie. My memories are 20-yrs old, of course, the situation might have changed since. But alas, at the time, this would only happen in rural areas, while urban communities were awash in concrete, owing to the fact that the local elites had shares in cement factories and... well, you get the logic. The concrete of course is susceptible to mildew, tends to crumble after a while and does not "breathe" well, not to mention how ugly it looks when big black living blotches overtake it randomly... So that glorious building tradition was on the brink of extinction. I hope and prey it will enjoy a revival.

    Great observation, @Maja Vujovic. Certainly Sri Lanka has a history of impressive structures and technology. I remember touring there in the 1970s and being particularly impressed by the ruins of Anuradhapura. #6

    I've seen many traditionally built houses when I lived in Sri Lanka, and seen people first-hand erect them very quickly. The prevalent material there is straw mixed with dung, which of course dries up in the sun and gives off no odours. It's also very easy to patch up any cracks over time. You wouldn't believe the solid shade and coolness this provides inside, without any mildew anywhere. And Sri Lanka is very humid, plus battered with monsoon twice yearly, for months on end.

    Fascinating. I wonder how they would hold up in a humid climate though. I am guessing quite well since as you mention, thatched roofs have long been used in England - Hence Margaret Thatcher came from a family tree of thatchers.

    I could've thought that this kind of material would be very flamable but now I see the solution for this, it's interesting how much materials are coming up for sustainable projects. I think that these kind of techniques should be taken to 3rd world countries in a massive way so people can start having a roof over their heads. Great share @Claire 🐝 Cardwell

    Interesting concept, Claire. As with all innovative materials, I suspect it may be hard to establish as an alternative concept for large scale housing, outside the one-off novelty, without credible research regarding its longterm durability, strength, fire resistance, resistance to insects, etc. Has much research been done in South Africa on these aspects and is there any sign of it being adopted with any confidence as a viable alternative to more conventional materials?

    I had heard of straw being used for sound proofing but this is a fantastic use of a material that as the article indicates is largely 'waste material'. Great ideas here!
