Reckless farming is harming the planet. This could save it

The United Nations released a dire warning recently: Climate change is here and it's a clear and present danger to our entire planet. Of course, we didn't need another report to tell us that — we see it in extreme and unusual weather, disappearing wildlife and falling farm yields. But there is one major cause of this global catastrophe that doesn't get the attention it deserves: industrial-scale chemical agriculture. Story here.

Plastic Proliferation Threatens the Climate on a Global Scale

CENTER FOR INTERNATIONAL ENVIRONMENTAL LAW.

The plastic pollution crisis that overwhelms our oceans is also a significant and growing threat to the Earth’s climate. At current levels, greenhouse gas emissions from the plastic lifecycle threaten the ability of the global community to keep global temperature rise below 1.5°C. With the petrochemical and plastic industries planning a massive expansion in production, the problem is on track to get much worse. Story here.

New research shows affected areas are losing ice five times faster than in the 1990s, with more than 100m of thickness gone in some places. Story here.

Two-thirds of world's longest rivers throttled by mankind: study

The design of the "site c" dam in B.C.

Almost two in three of Earth's longest rivers have been severed by dams, reservoirs or other manmade constructions, severely damaging some of the most important ecosystems on the planet, researchers said Wednesday. Story here.

Microplastics in freshwaters

Microplastics in sediments from the rivers Elbe (A), Mosel (B), Neckar (C), and Rhine (D).Note the diverse shapes (filaments, fragments, and spheres) and that not all items are microplastics (e.g., aluminum foil (C) and glass spheres and sand (D), white arrowheads). The white bars represent 1 mm. PhotoS by Martin Wagner et al.

As small as a grain of dust—but of great global significance. The word microplastics is familiar to many, but the dangers are virtually unexplored. In recent years, plastic pollution has become an ever-increasing burden on the environment. Countless videos and media reports draw attention to this problem. While the dangers of large plastic pieces for animals are impossible to overlook, there is practically nothing about the dangers posed by microplastics. But what are microplastics anyway? Get the answer here.

Jury rules Roundup gave a California couple cancer - orders the manufacturer, Bayer, to pay $2B.

It’s a record settlement in a Roundup case, so far.

In Canada, there are no signs of similar court actions, even though  Roundup is generously applied here, too. 

Sadly, our Canadian regulators seem far from vigilant in protecting the public against harmful chemicals. For example, less than a year ago, the PMRA re-registered a fungicide so its main uses can continue. That same product has just been banned in the EU as a possible carcinogen!

And the same corporation, Bayer, is busily registering (or trying to register) its latest insecticide for use, worldwide, including Canada. Never mind that scientists are questioning Bayer’s claim that it is not harmful to pollinators. 

The PMRA has been stone-silent on my own requests to justify this apparent inaction in either of these cases. I call it governance by neglect. 

It is to be hoped that punishing fines like this will eventually call this monstrous Corporation to heel and make it more accountable to the public good.

The government of one of Canada’s northern territories may soon adopt a recommendation which may well threaten the ability of the polar bear to reproduce. Story here.
