How many new species are being discovered?

https://stateoftheworldsplants.org/2017/new-plant-discoveries.html

1,730 new species discovered in the single year of 2016.

So for those keeping score, 571 extinict in 250 years versus 1,730 new species discovered in a single year.

If one does a simple linear extrapolotion... which is never correct to do, but is quite popular among certain Environmental Groups... Let's see how these numbers compare:

571 / 250 = 2.284 loss per year

or

1730 * 250 = 432,500 gain per 250 years

So... No, the Earth is not currently experiencing a Great Dying due to evil hummans and their awful Industrial Revolution.
