I quite agree with what you said, all or more than one of the above approaches should be applied.
Point number 5 seems to me to be a very good one. I can understand that people can't be persuaded to reduce meat consumption, for such a thing impinges upon freedom of choice. But wastage of food...
Yes , then that is good.
But I heard reports similar to the following that suggested that cattle feed is foodgrains :-

Such practices seem wasteful.
But , in case cattle can be supported on...
Wow, thanks for fishing out this piece of info. I was looking for something like this.
Now I will try and develop a taste for pigeons , rats and not to mention http://en.wikipedia.org/wiki/Common_House_Gecko" [Broken].

But the cattle will still consume lots of fodder for it's entire lifespan , say 3-4 years on an average. And that fodder will need land. And in the end the cow will be eaten in a week or so. The farther our diet is from the solar energy in the food-chain , the more resources consumed.(A...
Wouldn't you rather have tofu ? :biggrin:
No just kidding.
Yes, you are right . I did mention it in my first post that changing food habits is not practical.
But what I meant was smart changes in dietary patterns. Not complete abstinence . That is way too extreme.
But if a person on...
Or is it because she wants to share food with us ? Give-and-take, maybe ? We give her cat-food ,so on occasion , when she brings home food, she maybe wanting us to have a bite or two.
How do cats view their owners is a question that props up in my mind. Cats in the wild are solitary animals. So...
Most of the world consumes non vegetarian food significantly. http://en.wikipedia.org/wiki/Virtual_water#Agricultural_products" compares the virtual water requirements of various food products :-
I am showing the water requirements just as an example. But even land required to produce 1 kg...
I've a white cat. She is semi-domesticated, i.e she spends half of her time inside our house and half of her time roaming outside.She visits our apartment on the 5th floor of the building. Whenever she catches a prey be it a rat or a pigeon , she has a tendency to meow a lot in front of us. She...
"Any thing that is a Greek, is a man in virtue of being a Greek."
I think I will have to read some literature before I can understand whether this statement has existential quantifier or not. I am simply unable to decide and hence I am confused about it.
The if-then statement I am somewhat...
"Any thing that is a Greek, is a man in virtue of being a Greek."
Now I am confused , doesn't this imply something about existence of Greeks.
However ,
"For any x, if x is a Greek, then x is a man." , this one seems better. But this is just writing the if-then statement in a more formal way...
This seems a good point to me.Could you provide some good references to the above. I would really like to learn more on this point of view.
I am not sure if we can use "anything" as "it" . The statement "Anything is Greek" can't be taken in isolation. It seems meaningless.(although, "It is a...

I want to know whether I have understood this right.
We shouldn't be saying , "All Greeks are men,all greeks are white,therefore some men are white".
So we should be saying "there are...
yes N(a,b) takes a pair of natural numbers (a,b) to a single natural number N. But why should the other way around be a problem. Since the map is injective (as the problem asks us to prove) , there would also be an inverse map N-1 such that N-1(N) = (a,b).
of course proving it that way would be...
Homework Statement
Prove that the function N = 1/2*((a + b)2 + 3a + b) is an bijective map from the set of natural numbers to the set of pairs of natural numbers (a,b).
