Just because something seems intuitively obvious does not mean it is true, and it certainly doesn't mean government institutions will accept it as fact. If a credible, peer reviewed scientific study demonstrates a societal issue that is a small step towards real change.

If you close one eye your brain ignores the signal from the closed eye. That is what people who are completely blind see, nothing.

The moon is extremely far away from earth, even if you could throw objects from the surface to escape the moon's gravity they would still just fall in a ever so slightly smaller or larger orbit around earth and would never go anywhere near the surfcace.

I worked in a lab researching this a few years ago.. our studies found fatalaty rates of bleeding and transport around 33% at the time. Also the amount of blood you can collect is proportional to their size so companies were deliberately collecting females which are larger, causing extremely skewed sex ratios in the surviving wild populations (10 males: 1female). Also the synthetic substitutes are nowhere near commercially viable but the research is promising.

Not if we continue to harvest them for their blood unfortunately

Sorry I at least editted in the correct title of the paper, hopefully someone can help

In the fall the Indigo Bunting becomes restless and wants to constantly move towards their southern migration. Studies were conducted in an observatory with a simulated night sky. With a normal sky the birds almost always trended in the correct direction (south) even if their magnetic sense was interupted. scientists then had the observatory simulate the night sky rotated 180 degrees and noted that the birds now wanted to go north.

Edit: apparently I am bad at making links can anyone help?
