I have figured this out, there is a logic hole in HL2 when it comes to leeches if leeches have eaten all the fish in the ocean, wouldn't they all starve? even if there was canabalism, they would eat each other before they could mate that means leeches could not properly exist on earth this seems to apply for other xenian creatures too (antlions and headcrabs) thoughts?
except they evolved to photosynthesize. They just enjoy meat more, but will not resort to cannabalism.
Where did it say they ate everything in the ocean?
I doubt their bodies could withstand deeper ocean pressures, meaning they are forced to stay near the coast, which explains their extreme concentrations in such areas.
Plus, the events of HL1 through HL2:EP2 have all taken place in a relatively short period of time. It would take a long time to totally destroy a species (of any type).
Think - in nature, do animals not eat eachother? But deer don't just go extinct in a few years because the wolves eat them a lot. There are a lot of animals on earth, a lot of fish in the sea. Just because they can eat through human skin (which is all in all like a wet paper towel) doesn't mean that they can do the same to say, whales.
As you can tell by the gameplay, its not so much that the aliens (excluding combine) are more advanced than the creatures of earth, its just that they came so fast and in such large numbers. Point being, earths creatures would stand a fair chance against some of the aliens of Xen (headcrabs, leeches, all that stuff. We probably wouldn't do too well against antlions because they are giant bugs..meaning they are dangerous/hardy and reproduce prolifically).
no the thing is, in Lost Coast the fisherman says Hope you enjoy leechs implying they've eaten all the fish(plus I heard that someone said there are no fish left in the ocean), leeches devour pretty much anything they find also with antlions there's just too many of them, what do they eat? Theres not much they can because nothing is stupid enough to end up on the beachs oh and its been 20+ years since black mesa in HL1
Perhaps all he can find are leeches.
Also, I really don't consider Lost Coast as cannon to the Half-Life story as Lost Coast takes place during Half-Life 2 and Half-Life 2 doesn't really show any room for it.
Yeah I dunno about whether lost coast is cannon, since it was meant to be an expo of hdr, and as the guys at valve said, it was originally meant to be in the middle of the campaign.
However, I wouldn't say that the lost coast is entirely uncannon. Basically I'm not going to use it as a cop out (I think that everything that happens in lost coast is realistic to the story of half life 2, save for the fact that gordon never went there).
But a small town fisherman is restricted to the shallows of the ocean. Just because all he can catch are leeches doesn't mean that deep down in the ocean there aren't fish. Consider my argument on pressure. If one whack from a crowbar/handgun/anything can kill a leech, there is no way they could survive in the deep sea where pressures are so extreme.
Antlions presumably eat the naturally existing wildlife of the local area, and once that resource was exhausted, they likely targeted humans and aliens. Again, there are a lot of animals on earth, and combined with the aliens, I have little doubt that the antlions could gather enough food. Also, they are basically big bugs, so their anatomy probably allows for digesting a wide variety of things (meaning they are probably omnivorous).

Technically, it's a bit more around 17-18 years seeing that Alyx has grown to that apparent age. She was at least 1 or 2 years old back at Black Mesa ('98) and she now looks 17-19, so Gordon was in stasis within the years Alyx wen from 1-2 to 17-19. This makes it 16-20. I don't think it goes over twenty years.
But yeah, I agree about the fish thing to the guy above me. I may not believe in evolution, but I do believe that many fish types that can survive such water pressure, would retreat deeper into the ocean. These leaches are so tiny, I doubt they could survive deeper into the ocean, not that size has to do with everything, but these are so close together that I doubt they would go deeper into the ocean. You can simply put it like this when the argument comes to a dead end: Valve has lots of leaches attack you so you know not to go into the water. And if the players try to get really far out, they'll be dead by then because so many leaches attack all at once. We Valve makes nearly everything in Half-Life so closely related, and all explained perfectly, so they might have their own explanation, like the guy above me.
