I think it might be a dandelion...

whatever it is, the little fellow has some spunk. New tarmac and this tiny little thing pushes through it like it is tissue paper. One is reminded of Samuel Beckett and 'Not I':
: . . . . out . . . into this world . . . this world . . . tiny little thing . . . before its time . . . in a godfor? . . . what? . . girl? . . yes . . . tiny little girl . . . into this . . . out into this . . . before her time . . . godforsaken hole called . . . called . . . no matter . . . parents unknown . . . unheard of . . . he having vanished . . . thin air . . . no sooner buttoned up his breeches . . . she similarly . . . eight months later . . . almost to the tick . . . so no love . . . spared that . . .
And so on!
It is quite clear that when we have destroyed the planet, or the rich nations have done so, it will only be humankind that disappears - much of nature will carry on regardless without us, no matter how much tarmac and concrete we lay. Humans may perish, along with many other species, but chaps like this will find a way.
