The issue is that there is an misunderstanding of what is happening and location.

Based on u/garlicroastedpotato first comment of this

>This isn't fracking. This is the Canadian oilsands.

He is very likely referring to the open pit mining/surface mines of the oilsands. It is pretty much what everyone refers to when they say the oil sands.

The article is talking about the oil sands formation. It is actually fairly large, it goes so far south that the oil fields in Montana and North Dakota are part of that oil sands formation. To get access to the oil in that formation, if you are not doing open pit mining you are pretty much doing drilling which is part of the process of fracking. On top of that Fracking and Steam-assisted gravity drainage is very similar in nature.

And considering u/garlicroastedpotato said it isn't fracking in his comments, he has to be referring to the open pit mining commonly referred to as the Canadian oilsands.

And if you look at the article, the earthquake is around the the Peace River oil sands deposit. Very far away from the open pit mines.

Ergo, u/garlicroastedpotato is both right and wrong. He is right in what is happening, but wrong terms and locations. And because he used the wrong terms and location, he is overall wrong.

I think expressing trust as a percentage like that is more to get the point across than some sort of internal metric the person keeps track of. Boils down to "if you burn me, we can still be friends but i will keep my gaurd up" which seems pretty reasonable. You don't trust everyone equally to begin with (or shouldn't anyway.)

Findings in title quoted from the linked paper^1 and a summary^2 from the University of Tokyo.

From the linked paper:^1

>We do not need living organisms, but the existence of life in exoplanets can be probed by remains of microbes, microfossils, minerals produced by biological activities (biominerals), or any other signatures of past biological activities (e.g. concentration of biological molecules or isotopic ratios) (Cavalazzi and Westall 2018).

From the summary:^2

>“I propose we study well-preserved grains ejected from other worlds for potential signs of life,” said Totani [of the University of Tokyo’s Department of Astronomy].

>“The search for life outside our solar system typically means a search for signs of communication, which would indicate intelligent life but precludes any pre-technological life.

>“Or the search is for atmospheric signatures that might hint at life, but without direct confirmation there could always be an explanation that does not require life.

>“However, if there are signs of life in dust grains, not only could we be certain, but we could also find out soon.”

> 

>The basic idea is that large asteroid strikes can eject ground material into space. There is a chance that recently deceased or even fossilized microorganisms could be contained in some rocky material in this ejecta.

>This material will vary in size greatly, with different-sized pieces behaving differently once in space.

>Some larger pieces might fall back down or enter permanent orbits around a local planet or star. And some much smaller pieces might be too small to contain any verifiable signs of life.

>But grains in the region of 1 micrometer (one-thousandth of a millimeter) could not only host a specimen of a single-celled organism, but they could also potentially escape their host solar system altogether, and under the right circumstances, maybe even venture to ours.

>There may be such grains already on Earth, and in plentiful amounts, preserved in places such as the Antarctic ice, or under the seafloor.

You typed a lot but said essentially nothing past "participate at local elections" which doesn't focus on the problems of not having time to research candidates or that only a certain "type" of person gets the chance to run for local office. I really think that you aren't as aware of and educated on the issues you pretend to care about

To be fair, Canada probably has one of, if not thee worlds most stringent set environmental laws and regulations. Of course this doesn't mean they can't be improved on but it certainly puts the rest of the world into perspective if you think Canada is lacking in that department.

Odd title. "Road noise" is typically what we call the noise that comes from your car'd being in contact with the road itself - road noise is louder on bumpier roads, more quiet on smooth roads. It also depends on how much noise-dampening ability your car's cabin has.

The sounds of traffic are different.
