-Spread of Invasive Species
-Pollution (from both natural and human sources)

Man is only one factor that affects extinction and endangered species.
How can you say man is only one factor? You have tunnel vision or your
way of thinking is only as you want. Acid rain. Pollution, Habitat
change, Hunting, I can see more than one.
To put it another way, what's dumb about M's list is that man is
in fact responsible for most of those "other factors" today too.
Other factors on the list, eg volcanoes and meteors, last happened
millions of years ago and are not causes of endangered species
today.
Do you know how many volcanoes have erupted recently, and what sort of
damage they've done to the environment?

According to the Global Volcanism Program at the Smithsonian
Institution, as of December 2014, there have been a little over *400*
confirmed eruptions in the world *since January 2004*...
*How do volcanoes affect the environment?*
An erupting volcano emits gases and dust particles that can cause
profound changes in weather and climate throughout the world. Volcanism
also *affects the environment by producing acid rain* and making ocean
water warmer.
The sulfur dioxide that large volcanic explosions hurl into the
stratosphere mixes with water to create sulfuric acid. If the acid
droplets are large enough, they prevent heat from escaping Earth's
atmosphere. That results in higher temperatures, an element of the
greenhouse effect.
The carbon dioxide released by volcanic activity is a greenhouse gas.
Greenhouse gases are responsible for extreme weather and temperature
increases around the world. Among the consequences are health problems,
crop failures and the loss of habitat for animals and plants.
Eruptions might warm the water on the surface of the Pacific Ocean,
triggering the El Niņo effect, a weather pattern that brings about
torrential rain or heavy snow in some places and drought elsewhere. Acid
rain, which contaminates water sources, is another environmental effect
of volcanism.

That said, it's obvious you and I aren't going to get along, and I don't
have any intentions of calling you nasty names, either. With that I bid
you farewell on this topic.
