Though it is true that pollution does affect amphibians, and this was considered to be the leading contender for their reduced populations. Currently the main concern is a widespread fungus which apparently has spread globally and is harming many frog populations. This is very unusual in that it does not seem to be something caused by humans. It appears to be in fact a natural phenomenon. It is unclear whether their populations will recover from it or not. A group has gotten together to capture and raise the most endangered species in captivity until the fungus problem resolves itself and they can be re-released.
BTW amphibians are still considered a VERY important early warning sign of pollution since their eggs are exposed to it for as extended time (their eggs lack shells).

Some are, many have undergone sharp population declines, and the population status of many is not clear. Like many organisms, frogs don't get noticed very much - you have to actually hunt for most of them, and even if you do a census now, you may not have good information about the population 10, 20, 50, 100 years ago to compare it to. For most of us, it's an anecdotal-level feeling: "When I was a boy, you could find lots of tree frogs or Leopard Frogs; now you hardly see any.."

lol; if extinction of species were to refer to the rate at which humans eat them; then, I think frogs are going out of extinction.Asians eat these at an alarming and geometric rate, lol. They are a delicacy. Visit Chinese restaurants, lol

on their way to it-pollution has altered their reproduction organs anatomical structure in size and shape so they can't fertlize or inseminate the opposite sex properly to yield a viable number of offspring to continue their species.
frogs are also the best indicators of a ecosytem so what happens to them will happen to other animals in the ecosystem working up to the next level of the food chain.

They're actually getting mutilated from the pollutions causing the stagnant water we have today.

It appears they are rapidly on the decline but widespread flooding will help recovery.

No they are a very reproductive species.
