What can I do about feral and stray cats in my area?

If you want to help the cats and ecology in your local area the best thing to do is to work with your local animal shelters and local government to push for more spay and neuter programs. You should also just tell other people what you know about feral cats and stray cats, it helps for a community to be well informed, especially because if people are at least aware of a problem they are much more likely to do something about it. There is a lack of reliable reporting on the amount of feral cats in America, but if everyone in a local community is on the look-out it becomes much easier to get numbers and gauge how big the problem is in your area. What you should not do is hastily take matters into your own hands, if your area has a real feral cat problem don't be the one to resort to lethal control all on your own- bring up the problem to the local shelter and local town hall meetings, if you know there is a feral cat colony near you don't take it upon yourself to catch them unless you have training or are being advised by an authority on the matter, or else you could harm not only the cat but also yourself. Remember that change starts with information and is furthered by action, the fact that you are here reading is a step in the right direction!
