(Fun fact, Homo sapiens is Latin for ‘wise man', but we'll get to that later.)
All life has an impact, as does what we call ‘natural disasters’ (mostly when it occurs to people) but humans have really done a job of it.
Not only in driving native species out of their territory, but in bringing in non-indigenous ones to eradicate the first, only to find it did more harm than
good. It is done with plants as well as animals, many of them adapting so well they become the dominant species of the area.
Humans have done it naively (as in life hitching a ride on modes of transportation), as well as ignorantly on purpose.
Some have been harmless enough, but others, devastating.
And it continues.
Inter-breeding, creating hybids, from that which might never have done so (or had the opportunity to) is another way (as with livestock, dogs, cats either beneficially or simply for pleasure.)
It has been done for centuries.
And now cloning. Can't forget that.
Same with plantlife, genetically modifying them, splicing one to another, etc.
Yes, we have done a lot of manipulation to the planet itself as well as the life living upon it.
But that is because we have a larger brain and opposable thumbs and are the
superior lifeform, so we know what is best.
Except perhaps for the microscopic, such as virus, bacteria, parasites and so forth that we are hosts to.
In the end, it may be what is invisible to the naked eye that wins....that is, of course, barring the fact that we may just destroy ourselves along with everything else.
Because we are superior.
‘Wise [wo]man’ (yes, it refers to both genders although, mulier sapiens would be ‘wise woman’ but why be picky, and anyway, I don’t like the sound of that, seems too much like ‘mule’, but then homo hasn’t the nicest ring to it either anymore. Maybe it should, in all fairness, be homo-mulier sapiens. And maybe not.)
(And maybe none of the above.)
(yes, I am in a mood. More to come -_- <very serious face.)
