How can two species compete for the same resource even if they never come into contact with each other?

Answer 1

I have a patch of allium plants in my back yard.
The pocket gophers eat them by pulling them underground from below.
I eat them by cutting leaves off them.

I never come into contact with the gophers. Believe me, I've tried, and if I did come into contact with a gopher, there would be one fewer gopher in my back yard, and I wouldn't be sharing my allium plants.

Answer 2

I like this question.

I like most answers so far.

Yep, many ways. Resource can be shared like oxygen over wide range. They may be in different times.

Plants compete for some resource but might not come in direct contact.

You have resources that move like say water, air, fish, etc, etc,

In short, in many many many ways.

Answer 3

the classic technological knowledge fiction reaction is to attempt to kill it, for no different reason than the actual incontrovertible truth that that is diverse. this will be a huge mistake, fantastically if the alien species has come to us on our planet. in the experience that they could bypass the large gulf of area basically to come back and say hi in man or woman, then we should not be giving them an excuse to squash them. we ought to continually be very large to them and save on with all of their ideas like good little ones. for sure, that ought to artwork antagonistic to us. In "V" the extraterrestrial beings genuinely took over the planet, and began secretly harvesting people for nutrition - the authentic reason they'd come. If extraterrestrial beings arrived, it should be difficult to end them taking on, yet that doesn't end us from attempting, i assume. possibilities of success will be small to nil although. i assume your question isn't unavoidably about them arriving on earth, yet basically making contact with them. secure distant contact will be more beneficial for people. in the experience that they were a procedures sufficient away that they does not worry making the shape, then a minimum of we may be secure from conquest. lets change information and study from one yet another. they could help raise us up out of this barbarity we are presently so awash in. yet there'll continually be those who do not trust what the extraterrestrial beings say to us, that they should be mendacity in order to trick us. which could be what people would do, yet who knows how alien minds will imagine, or what avenues their common sense will take? Alien way of existence may be peppered with many assumptions that we do not percentage, ensuing in "risky" options being given to the human beings. The church will be in disarray, yet would quickly replace its music so as that "for sure God made different worlds - did not we are saying that beforehand?" i'm hoping that searching alien existence, or data for it, would wake us up, make us comprehend there replaced right into a huge universe available waiting to be explored with the help of a united humanity.
