In the 1630’s and during what is now considered the Dutch Golden Age, contract prices for newly introduced species of Tulips reached astonishing heights that were completely removed from concepts of fundamental or inherent value. The rapid escalation of interest in the fashionable bulbs, however, dramatically collapsed within a few years causing what is believed to be the fall of the first speculative bubble and the start of what is now coined the futures markets.
Fast forward 400 years, and it appears we are entering into another type of flora-based mania – this time under water – as venture capitalists masquerade to save the planet from carbon dioxide (CO2) and other equivalent molecules.
Enter into the discussion Algae, one of the most important substances on earth. A complex evolutionary masterpiece, there are approximately 12,000 known Algae species, and which are popularly (if incorrectly) merged into the term Seaweed.
The Seaweed family contributes more than we could ever understand to life on earth, from sequestering CO2 from the earth’s atmosphere, to supporting the base food source of all marine life, through to cures in modern medicine and the foundation of the skin and beauty industries.
And Asparagopsis Taxiformis, a red seaweed species, is no exception. It is marketed as a leading solution to combat methane emissions, and has shown to reduce ruminant enteric methane (CH4) production up to 99%, decrease the carbon footprint of ruminant livestock and potentially increase production efficiency.
Across Australia, New Zealand and many other parts of the world, the race is on to produce, refine and manufacture this wonder seaweed due to its incredible effects on reducing methane in the ruminants of Cattle, Sheep, Goats and Deer.
In Australia the market controlled by a joint venture between CSIRO (Federal Government Research Agency), James Cook University and producer owned Meat & Livestock Australia held under the entity ‘Future Feed’. Future Feed licenses companies to grow, harvest and manufacture the seaweed for commercial use in feedlots.
Large scale investment and government grants have produced seaweed farms across the southern shorelines of Australia and New Zealand with hundreds of millions of investments. And with the intellectual property seemingly locked up, investors are in a frenzy to lay their claim. And like any bubble, it seems few are pausing to address either the potential harm to humans or impacts on the environment of the associated growing, harvesting, manufacturing and distribution channels.
It is well understood that the active ingredient in Asparagopsis Taxiformis that reduces methane is the compound Bromoform (CHBr3). The first challenge for proponents and investors of this Seaweed is that in its raw form, Bromoform is a carcinogen. It could have immediate and long-term effects on the nervous system depending on the amount and frequency of exposure. While human data thus far is considered inadequate in providing evidence of cancer by exposure to Bromoform, animal data indicates that long-term oral exposure can cause liver and intestinal tumours. On the question of whether Bromoform administered to livestock will find its way into the food chain, a recent study from a Dutch University (Wageningen University and Research) concluded that in dairy Cows tested, Bromoform was found in samples of both milk and urine. This concerning transfer and retention of Bromoform has of course been vigorously defended by Future Feed as it pushes the boundaries of production with the few licenses it has granted, creating scarcity, demand and an economic bubble.
The second challenge is that to materially reduce methane emissions from cattle, the recommended daily dose for cattle is understood to be approximately 0.5% or less of highly bioactive Bromoform. With 27 million head of cattle in circulation annually in Australia and only 4% in a feed lot environment at any one time, how this dose is efficiently administered is anyone’s guess. Sheep, Goats and Deer are even less controlled.
The third challenge is the carbon footprint of growing, manufacturing, and distributing this form of seaweed. By way of example, the Australian company Sea Forest is licensed to grow the seaweed product in a suitable environment off the far south-eastern corner of Tasmania. The electricity and diesel used to grow and harvest the seaweed from the oceans, coupled with the high electricity output required to freeze dry it and the subsequent distribution to feedlots on mainland Australia (often over 3000km away), are staggering for a commercially unproven and potentially unsafe emissions reduction product.
As a cautionary tale, in recent times the New Zealand dairy industry was hit with extreme export sanctions from China on the basis of a perceived threshold issue relating to the DCD nitrogen prohibitor in dairy cattle. This locked NZ out of trading dairy items with China for 12 months, costing the industry and investors heavily.
Just as tulip traders met with overzealous buyers in smoky taverns in the Netherlands in the mid 1630’s, we are today confronted by frenzied investors and venture capitalist players chasing a potentially harmful and environmentally risky product that may well be better left in the oceans to absorb CO2 naturally and replenish the marine ecosystem.
