Coal mining
March 11, 2025
Everybody knows we are living in an age of disinformation and we need to be alert so we’re not taken in when it comes our way. The subject of an earlier letter was coal mining, until it went off on a bit of a tangent into climate change denial.
The letter seemed to be about coal mining on the eastern slopes, but referred to the four Teck mine sites on the western slopes in BC and claimed the rivers and valleys were “pristine.” Not quite. For example: It’s taken the Ktunaxa Nation 12 years to convince the US and Canadian governments to convene the International Joint Commission to look into the pollution (especially selenium and calcite) in the Elk and Kootenay Rivers caused by the mining of coal.
The letter said that renewable energy sources require far more land than coal mining, and claimed that a 2,000-kilowatt solar farm would occupy 80 square kilometres (about 20,000 acres; that’s 80 km x 1 km, or about 9 km x 9 km, not 80 km x 80 km as claimed in the letter!). But, I’ve got a 332 square foot 5.3-kW solar array on the roof of my house; expand that to 2,000 kW and we’re up to almost three acres (nowhere near 20,000 acres).
Furthermore, renewables, like wind and solar, can be compatible with agriculture; also, the renewable installation stays put, unlike coal extraction, which depletes one area and expands to mine another. The Elk Valley mines in BC already have a footprint of about 113 square kilometres (as of a few years ago) and are expected to expand beyond that. In Alberta, coal companies have leases to explore, and potentially mine, 1,880 square kilometres of land. The land disturbed for coal exploration and development is immense in comparison to renewables.
The letter’s comments about atmospheric carbon dioxide are so preposterous I don’t really know what to say. Sure, 0.04 per cent doesn’t sound like much, but Earth’s atmosphere is pretty big and there are lots of carbon dioxide molecules to allow the sun’s visible wavelengths in but prevent some of the resulting infrared radiation from leaving, and this causes increasing temperatures. The carbon tax cannot “tax us into poverty” because it is set up to refund the tax to those who cannot afford it; even I, who could afford it, get back, I’m sure, more than I pay.
Everybody knows that “do your [own] research” is a euphemism for “don’t trust/believe science.” I say, if you can’t trust/believe science, who can you trust?
