Asteroids, Nuclear Wars, even (though extremely remote) Black Holes?! There are so many factors that in the end could decide the fate of human civilization! The only reason that we, as a race, are here in front of our keyboards today is since we were lucky. There were many plagues, epidemics, and other disasters that had the potential to end Human civilization, but Nature decided it wasn't our time. How do we know we'll be so lucky in the future?

I mean to say, remember the Black Plague that swept through Europe? It wiped MILLIONS of people; men, women, and children.
One asteroid alone ended the dominant species of their time, the dinosaurs, so who's to say that couldn't happen to us. As the dominant species of this earth, WE are the ones at greatest risk.

My question to you all, what can WE, as a people, do to prevent such a calamity?

Climate Change - Are We Doomed ?

If you were to stop all economic activity throughout the planet, would this arrest the rise in global warming ?
Just think that, if you could remove all of humanity from the planet, this would allow the rain forests ro regenerate and stop the relentless increases in CO2 and SOx's.
Perhaps I have answered my own question.
Anyone got any ideas ?

I'm not quite sure how to factor these expressions...?

I need help factoring these expressions.

1.

((3MN^2 - 3 M)/(N) x ((3M)/(N^2 - 1))
In case this is confusing, those are two fractions being multiplied.

2.

((48B^2 + 8B + 7)/(12B - 1))
Also a fraction (only one this time though)

3.

((x^2 + 4x - 5)/(x^2 - 2x - 3)) + ((2)/(x+1))
This time there are two fractions being added.

If you don't mind, please explain your answer.

I know how to factor. This is a review of what I learned last year and it's not graded. I just cannot get these 3 problems.

If I get an answer I can go back and see how to get to it. I'm not just going to copy answers from anyone without seeing how it was done.

Is there weakness in the Stealth Bombers "invisibleness" ?

I think there is. I wached someting about the Stealth bombers invisibility to Radar. Because, the waves just break up after hitting it. Due it's angular design. But, isn't it possible to hear it coming. Using somekind of modified sonar technology or maybe it can be seen with specially positioned infrared telescopes ?
