Once I up or down-vote a post, I never see it again, unless someone responds to something I wrote. If there's something I want to check later, I have to Save it.
If I respond to a post or comment, and then that gets edited, I'm pretty sure I don't get notified. And since I've already up-voted it, I'll never see it again (unless I Save it and remember to check it later).
If a post is more than a day old, and the info you're editing is important, make a new post. Reference the first post if necessary.
I played with this a couple times. Once it located a nondescript stream in the UP of Michigan to within 200 miles. It knew the picture was taken in the UP. The second was a ferry dock in a foreign country (English speaking). It found a sign and that misdirected it to the other side of the country.
California is "abandoning" these because they need EPA approval, and the EPA has dragged their feet. Since the Trump admin is unlikely to grant approval, California isn't going to waste time and money on it.
The earth gains somewhere between 40,000 and 100,000 tons every year, just naturally due to space debris. But I've also read that that's offset by atmospheric gasses leaving the atmosphere, so the earth is actually losing mass.
But there's also the question of how much of that mass entering or leaving is actually affecting the system mass. Any additional mass entering orbit of the earth and moon should affect the earth's orbit as well.
And then, there's the "slingshot" effect where items traveling /with/ the earth's orbit can steal orbital speed from the earth, or when traveling /against/ the earth's orbit can add orbital speed to the earth.
So, the answer is: it's complicated.
I personally don't think it's much to worry about. Before we add enough mass to the earth to affect the orbit, I think we might notice a gravitational change.
âPlants need carbon dioxide along with sunlight, water and nutrients to prosper. The more carbon dioxide available for this, the better life can flourish.â
Someone should demonstrate the effect of too much water on the human body.
I add to make a password last fall that had the requirement "numerals or special characters". A password with both numerals and special characters wouldn't work.
