If industrial pollution continues to deplete the ozone layer, the resulting increase in ultraviolet radiation will endanger human health, causing a rise in the incidence of skin cancer and eye disease, and perhaps even threatening global ecological systems.
As written "ultraviolet radiation will endanger human health, causing ... and perhaps even threatening ...", the sentence seems to present two HOW-aspects of the action "will endanger human health".
It is not correct as "causing a rise in the incidence of skin cancer and eye disease" definitely explains how UR causes bad things to human health, but "threatening global ecological systems" is not. This is an incident of forced parallelism, the second part does not explain the effect of UR of health rather completely different effect.
We need an answer choice that makes parallel another list: "will endanger" and "will threat".

- incorrect for the reason explained above

- correct
Quote:
- "and" requires us to maintain parallelism: noun ("a possible threat") is not parallel to verb ("will endanger")

Let’s simplify the sentence:
If pollution continues, the increase will endanger X, causing …, and [threaten] Y.
We can see that X and Y have to be parallel and the verb forms as well. Based on this we can eliminate the options:
(A) and perhaps even threatening – not parallel. Eliminate.
(B) and may even threaten – parallel. Best choice.
(C) and even a possible threat to – not parallel. Eliminate.
(D) as well as possibly threatening – not parallel. Eliminate.
(E) as well as a possible threat to – not parallel. Eliminate.
Hope this helps!
