Ocean acidification may have unexpected impacts

Alison Campbell Jan 20, 2019

A substantial proportion of the CO2 we release into the atmosphere, via burning fossil fuels, ends up dissolved in the ocean. The impact of this is a change in the ocean’s acidity: the pH drops. According to the Smithsonian, oceans have become substantially more acidic over the last 200 years (the period of the Industrial Revolution) – waaaay … Read More

WHO: ‘vaccine hesitancy’ is one of the top 10 health threats in 2019

Alison Campbell Jan 17, 2019

You read that right. Vaccine hesitancy – “the reluctance or refusal to vaccinate despite the availability of vaccines” – is viewed by the World Health Organisation as one of the top 10 health threats we face in 2019. And worse, that hesitancy will have an effect on other threats in that top 10 list. Ebola and the potential … Read More

Alison Campbell Jan 16, 2019

Every so often there’s a new story claiming that a study has overturned our understanding of human evolution. (Or something along those lines.) I’ve just come across another one**, & thought I’d write this post as a warning to year 13 biology students.

A pivotal species? What’s that?

Alison Campbell Nov 20, 2018

By the end of the school year, Year 13 students preparing for Schol Bio should have a pretty good grasp of the concepts and content they’ve encountered in their studies.

Agenda 21 and crank magnetism

Alison Campbell Oct 08, 2018

What with WAVES, and anti-1080 groups, and Rethink Fluoride (which, like FFNZ, opposes water fluoridation), there’s quite a lot of ‘alternative’ activity online these days. It’s actually quite interesting to look at the similarities that you can see in attitudes & opinions expressed on those sites. I mean, Agenda 21, anyone?

Anti-vaxxers’ dangerous misinformation

Alison Campbell Oct 03, 2018

That image is a visual counter to a now-removed billboard put up on an Auckland motorway by the NZ group WAVES (Warnings Against Vaccine Expectations). If you haven’t seen the offending item, this was it: That’s not a warning, that’s a scare tactic, and will surely have led to complaints to the Advertising Standards Authority. After … Read More
