A 25 year study by Welsh scientists has recently concluded and suggests climate change might be hampering the recovery of Earth’s rivers from the effects of acid rainfall.

This research study was conducted by Cardiff University Professor Steve Ormerod and biosciences researcher Isabelle Durance. The effort was undertaken in Wales and studied 14 middle-Wales rivers, involving the assessment of the number and variety of insects present each year in these rivers. The scientists said they also measured concentrations of acid and other aspects of stream chemistry.

For years the use of monosodium methanearsenate, or MSMA, was prevalent in British Columbia as a means to control Pine Beetles. Sold for a long time under the trade name, Glowon, it was considered safe and useful, posing no threat to the environment or to human health. This sounds like a song I’ve heard before, how about you? Even though this product was no longer in use as late as 2005, mainly because the manufacturer did not renew the permit, the residue of this product remains all throughout the region. IN fact, they are now issuing maps of areas that they are urging loggers to avoid because the residue is that bad. And what is the residue? Arsenic.

Now, my first question, as an intelligent, alert individual with common sense, is to ask how on earth anyone could think that arsenic, a known volatile and dangerous poison, could be environmentally safe and non toxic to humans? Seriously. To it’s credit, the US EPA decided in 2006 not to re-register MSMA as a pesticide because it “posed a cancer risk”. This is because of it’s potential to “transform to a more toxic inorganic form of arsenic in the soil with subsequent transport to drinking water.” Yep. You heard right. Drinking water is likely contaminated with this poison through natural run off.

And the Forest Practices Board recommended, in it’s 2004 annual report, that the ministry track MSMA treated trees to ensure they are not harvested or milled. This board found, in it’s studies, that MSMA was used near human habitation and that treated trees had been logged and milled within the past year. Therefor the restriction on access to these trees was decided upon.

Guess what? MSMA is still being sold in the US. I don’t know if anything will amaze me but this does upset me… does it you?

Most people are ignorant of the crucial role the rainforests play in keeping the global climate stable, a survey has revealed.

More than 60 per cent of people questioned thought air travel and domestic heating produced more greenhouse gases than the destruction of the forests.

Deforestation releases huge volumes of CO2. In fact deforestation releases more CO2 into the atmosphere each year than all of the world’s planes, trains and automobiles put together.

The survey commissioned by the Rainforest Foundation UK (RFUK) revealed that 62% thought more CO2 is produced by the UK’s housing stock each year than by deforestation. The truth is that cutting down the rainforests for agriculture and grazing produces more carbon emissions than all the UK domestic energy use. …Read More…
