How many sepecies are believed to exist?

I think it is either 1000 or 30 million. I looked in my book and that is what I found, but I can’t tell which one it is. Which seems more likely?

The truth is, its very hard to know, or even estimate. Currently there are about 1.4 million species described. Yet, we’re probably far from being close to the actual number of species.

World Resources Institute states there are between 2 million to 100 million with a best estimate of near 10 million, and only 1.4 have actually been named.

Scientists have actually classified around 1.4-1.5 million species.
