What are anthropogenic factors?

The primary anthropogenic factors produce ecological and genetic effects contributing to extinction risk.
What does the word factor mean in algebra?
factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The prime factors of a number or an algebraic expression are those factors which are prime.

How do you find factors in algebra?
Find two numbers that both multiply to make c and add to make b. Once you find these two numbers d and e, place them in the following expression: (x+d)(x+e). These two terms, when multiplied together, produce your quadratic equation – in other words, they are your quadratic equation’s factors.
What does by a factor of 3 mean?
Last year there were 3000 observations, this year there are only 1000. This is described as showing a “fall by a factor of 3”. This phrase doesn’t ring true. If a factor of 3 is a 1/3, then a fall by a third would be down to 2000. So the phrase is meant to represent a fall to a third.
