no
yes

More complicated than that OP. We are basically too late to stop irreversible climate change, but it can be slowed down. The slower the better. Climate change is a natural thing, but rapid change is not. Naturally it is a very slow process that happens in predictable cycles, but we have knocked the Earth out of its natural cycle for good. Rapid and unpredictable change will be a bad thing for us. We still have the means to slow it down so we can adapt as it happens.

Need to find a way to start rapidly taking carbon out of the atmosphere and oceans and making it solid.

We can put iron oxide into the ocean and cause massive algae blooms. Which will capture CO2 into organic solids and liquids. Though this will have other side effects.

Water consumption is basically just an equivalent of energy consumption.

>>7913155
In the developing world like China, India, Middle East? Yes. Contingency plans? Stop having so many people, which should slow the agriculture demand, and in turn allow for more water to be replenished underground.

In Russia and SubSaharan Africa? There's abundance of freshwater reserves (underground).

>>7913155
Yes, we are fucked if there is a disaster.
We humans have not self-organised well.
>>7913160
I wish, we can't convert sunlight to fresh water.
salination is not very feasible in the large scale and it is not very effective for providing water to the interior of continents.

2 times 4 every 25 hours

I'm retarded now.
Used to sleep 9 hours per 24h and was sharp as fuck.

>>7913118
Between 0 and 10 hours with no real consistent pattern.

I'm probably worse for it.

>>7913118
I have insomnia, so it's really dependent on the day.
Sometimes I just drink myself to sleep and am out for 12 hours straight.

>>7913091
salt makes you too lazy to fucking google "why is salt bad for me".

>>7913097

I don't want to hear it from google, I want to hear it from /sci/. I can goolge "why salt is good for you" and get a million reasons why it is. Doesn't mean its true.

Salt undoubtedly causes damage to your body, but the damage is pretty much negligible unless you ingest a lot at once. We're talking mouthfuls. Any damage caused is completely restored in no time at all. Dehydration can be an issue if you don't keep adequately hydrated regardless of salt ingestion. Otherwise, you're fine.

You bring up a good point

Look at America, for example.

You bring up a good point

Look at Britain, for example

You bring up a good point

Look at OP, for example.

companies do this shit all the time. they are called pump n' dumps, or boondoggles. basically you get to pay yourself a salary blowing through other peoples money while you basically do nothing, and its totally legal.

good work if you can get it as an engineer.

>>7912738
>will it become a reality?
Eventually.

Once you have a serious off-world economy going you'll see strange things happening though, the possibility of enforcing a space based economy will be challenging for earth governments.

I had a chat with one of my lecturers at uni about this once, he said asteroid mining is more than likely going to become a reality in our lifetimes since we're going to run out of certain materials/elements soon (like say, helium) and at that point it'll be a profitable investment. Although for the next 10-20 years at least, I don't really see it happening.

They are descendants of birds. Really "bird" is just the class aves of vertebrates. It doesn't imply that they fly.

They fly in the water.

>obvious bait
make sure not to fall for it guise

no one been a tutee or tutor at gcse or a-level? really?

>>7912538
I have I guess, why?

>>7912538
Yah, shit was mandated at my highschool, if that's the level you mean.

It isn't, it's expanding at 70km/s/mpc

don't reply.

>>7912437
Not an argument.

>>7912427
>climate change
obviously real.
>gender fluidity
can't be proven or disproven
>biological differences between races.
huh?

In order of answer:
A B C
D E F
35. F
27. D
32. D
34. Still couldn't figure out. Best choice currently is C I guess.

>>7912431
Edit: Just tried the test, got 143, the answer for 34 is not C.

>>7912431

Thank you so very much for your answer! :D

Could you pretty please elaborate the reasoning behind your answers?

>>7912156
Happened to me hundreds of times.

>>7912156
Know a kid that got a nosebleed before an exam

>>7912156
Me on a couple occasions.

Worse is that there's no proofs

They miss the essence of math in favor of mindless computation

Only shitty inner city school don't. All others have Calculus, and some go all the way to Multivariable.

>>7912147
American here.

Had logic and induction proofs in precalc.
However did not have any proofs in Calc.

>>7912101
oh also pic unrelated

The fuck is this shit

if you are asking about the picture it is a simple representations of genetic modifications I am working on for my grade 12 students

not possible
first take this example
all even integers can be represented as 2k, meaning that 2 is the only even prime
if you multiply infinity by two, you get infinity, meaning that infinity is not prime
of course you can also argue that infinity is odd
infinitely large primes is a nonsense concept anyway

Do you mean arbitrarily large?

It would be pretty big but the problem is out of reach of pretty much every non PhD student.

quantum computers (if they ever get made) can do that with their parallel processing
