If we all are against usage of plastic, what stops us from eliminating it completely around us.

#112The actual study is here https://www.sciencedirect.com/science/article/pii/S030438942... The study presents three scenarios assuming different assumptions about the mass of plastic particles. In the worst case scenario, where I think the assumptions are bad, they estimate 5g of plastic per week. In the other two scenarios which used more complex but more realistic modelling they estimate 0.15 and 0.3g of plastic cons…
I can't take anyone seriously who publishes a pie-chart like this: https://ars.els-cdn.com/content/image/1-s2.0-S03043894203199...

You might care to state why the chart is problematic.

nice. >In these scenarios (0.15g and 0.3g) about 90% they estimate comes from salt. for a few years now we have switched to rock salt completely at home. it's like 20-40% more expensive and we have to use a hammer/grinder every month or so but we are doing that. by reducing say 90% of the microplastics, is that.. good?
What makes you think that’ll reduce it?

That seems a rather arbitrary trait to dismiss a researcher for. It is possible to be correct with flawed design choices.
that pie chart to the left is not poor design choice. it demonstrates actual incompetency.
Why? The labels are given in absolute units but they are correct.

I didn't get it at first but you're right, it's horrifying. They put the total and the breakdown into the same pie chart.

Yes, you are of course right. One shouldn't dismiss good work because of some flaws. But anyway... this is a rather silly pie chart and I wonder how this was able to pass through multiple authors and peer-review.
The popular conception of science is really outdated in this respect. Peer review still matters, but most meaningful peer review happens post-publication, not pre-publication. People should not take published papers as reliable statements of "what the science says".
Scientists are not going to expend a lot of effort on the thankless work of peer review, taking time away from their own careers, purely out of professional integrity and the goodness of their hearts. And their competency to do so is uneven at best anyway. What happens when the people who wrote this paper review other people's data?

Yes and silicate is an environmental component that's well understood and our bodies have adapted to it because sand has been a thing forever. And glass is chemically inert.
Asbestos is a silicate…
And, in quantity, even the "harmless" silicates aren't.

Is that because the "Consumables ingested" on the right side looks like Pac-Man eating the other two categories?
The pie chart on the left double counts everything. The total is represented as a slice in the pie chart.
Probably a case of automatically converting an Excel column into a pie chart.
