A daring question: Is Homo sapiens itself an invasive species?

# data[].attributes.body
Invasive non-native species are species alien to an area that are introduced into it either unintentionally or intentionally and that spread quickly and cause a lot of damage to native natural or urban ecosystems.
So, what about humankind?
Humankind makes up about 0.01% of all Life and has caused, since the beginning of its appearance, the extinction of 83% of wild mammals and about 50% of all plants. We, ourselves, Homo sapiens, are causing tremendous damage to natural habitats. When are we going to put ourselves in check?

Based on the "evidence" given in the following article:

Theme 2: Two species that share the same food (niche partitioning) on Crete

# data[].attributes.body
The bearded vulture and the Griffon vulture share the same food - carrion. The way they share it is that when an animal dies, first the Griffon vulture approach in a large flock and devour the mammal's flesh. Waiting nearby for its turn, the bearded vulture (usually a single individual) awaits until it can get to the bones of the carcass, which is its source of food. So, the two species feed on the same carrion but eat different parts of it, efficiently partitioning their niche and are thus able to share the same habitat.

Possible signs of climate change on Crete

Possible signs of climate change on Crete

# data[].attributes.body
During the last decade the number of days with sand storms has been gradually increasing, beginning in spring and occurring up until late fall or even throughout the winter, though less obvious. Also, though winters are getting milder with less precipitation, there are days with extremely high precipication, as occured in October 2018, when on a single day the highest precipitation of over 300mm was recorded near the town of Chania. These weather extremes (in either direction) could constitute signs of climate change.

A highly invasive plant from Mexico.

# data[].attributes.body
Crete, being part of the Mediterranean, is an "area of intense cultural and commercial exchange" and as such, "it has been subject to the invasion of several species. Some have adapted and became incorporated into the local environment. However, many such invasive species alter natural ecosystems and drive local species of fauna and flora to extinction."
(NHMC, exhibit on Crete)
Examples:
- Red-eared slider (Trachemys scripta)
- American bullfrog (Lithobates cartesbeianus)

A most recent - 2016 - invasion to Cretan marine waters, the lionfish is now considered one of the most invasive species of the world.
It is poisonous but can be eaten if certain poisonous parts are removed.

(Lagocephalus sceleratus)
An extremely poisonous (highly toxic) recent invasive species!
First recorded in Greek seas in 2005. Causes damages to local fishing gear. But more studies and monitoring are needed to assess impact to local ecosystems.
