Well, i didn't mean it like that. My english isn't all that good, alrighty?
The internet can be said to be manmade, but it's not a construction. A bridge is a construction. A scyscraper is a construction. BBC News is not a construction, but still manmade. See what i mean?
...soooo. the part about bridges and blablabla wasnt questions, just a clarification. Hm.
EDIT:
I'm not making any sense, am I...
