Who knew about microbeads?

August 19, 2016

Not I. But when I checked our current tube of toothpaste, there they were.

This is a preliminary study so bear that in mind.

Microbeads could be turning the fish we eat toxic, study finds
Sashimi, please. Hold the plastic.

Scientists have found worrying evidence that fish are becoming toxic, as their environments are being polluted with billions of microbeads – the tiny plastic particles commonly found in face scrubs, body wash, and other cosmetics.

Several governments, including the US and Australia, are in the process of phasing microbeads out, but based on their findings, researchers are pushing for an immediate ban. […]


The world farm report

October 16, 2015

Matt Ridley writes about the (northern hemisphere) harvest season, both globally and on his own piece of land.


This week’s autumn equinox is traditionally the time for the harvest festival. I have just taken a ride on the combine harvester cutting wheat on my farm. It is such a sophisticated threshing machine that long gone are the days when I could be trusted to take the controls during the lunch break. A screen showed how the GPS was steering it, inch-perfect and hands-free, along the edge of the unharvested crop; another screen gave an instant readout of the yield. It was averaging over five tonnes per acre (or 12 tonnes per hectare) — a record. […]

Last week, my fields were yielding 60 or 70 grains (seeds) of wheat for every grain that had been planted a year before. This would astonish our ancestors. A farmer in England in the 1300s was lucky to get four grains for every grain he planted. One of those four had to be saved for next year’s planting, leaving a precarious three to feed not only his own family but the various chiefs, priests and thieves who fed off him.

The truly surprising thing about this bounty is that not only are yields going up and up, in Britain as in the rest of the world, but that the amount of land required to produce that food is going down; and so is the amount of pesticide and fertiliser. Not just in relative terms, but in absolute terms. […]

Here’s a related graph which appeared yesterday at Carpe Diem.


I’m not a farmer but I know a few. My guess is that one big factor driving this trend is the adoption of man-made fertilizers after World War II.

One fellow I know, who in his spare time helps his dad farm, told me that his dad recalls the days before anhydrous ammonia became available. Back then the only choice was to fertilize with manure and supplies of that were limited.


When wolves returned to Yellowstone

November 6, 2014

This article’s about a year old; I just came across it a couple of weeks ago. It sounds to me like the root problem was failing to keep the deer population under control. (I’m guessing they didn’t allow humans to hunt the deer in Yellowstone, so the wolves may now be doing something no one was doing earlier.)

But it’s a nicely done clip and makes a good point about nature’s balance.

When They Brought These Wolves Into The Park, They Had No Idea This Would Happen

In 1995, wolves were re-introduced into the Yellowstone National Park, after being wolf-free for 70 years. What naturalists and biologist never imagined, was that the most remarkable thing would take place. Mother Nature knows what she’s doing if we just leave her alone.
