This phenomenon may have started in the US, but they know very well they'll eventually reach some point of saturation in such a politically divided country. That's why creation science proponents are on an all-out assault on science throughout the world, especially in developing nations.
Oh, you thought it had something to do with missionary work and spreading the Gospel message? NO. These organizations (Institute for Creation Research, Creation Ministries International, The Discovery Institute, and a few other smaller ones) are big business. Look at their Web sites. From the very first page, they're either asking for donations or they're selling you their wares. Homeschooling textbooks, tracts, videos. Yes, the missionary work is integral to their purpose -- they need a wide audience of buyers. They're happy to do that too.
You aren't going to be able to counter this movement with any kind of science education. They have their own "science" now, any science from any other source will be viewed with tremendous suspicion if it conflicts with their view of creation. You need to work this at its source -- by educating people on the history of creationist thought, and the reasons *why* they believe what they do -- educate them on the *reason* why they have a certain *interpretation* of the Bible. If you're an atheist, you'll think it's easy enough, just discredit the Bible. But attacking a person's faith at its core is NOT going to help, it only adds fuel to the fire. So please DON'T take that approach. Seriously, it will make things much, much worse.
The only way forward is to educate Christians on creationism as a movement itself, in a way that is NOT abusive to their faith. Get people to learn specifically about the history of the three organizations mentioned above! There is a tremendous amount of dirty laundry there (see http://truecreation.info/ or the book Searching for Truth with a Broken Flashlight) Better yet, find respected Christians who they trust, who understand science -- and geology, cosmology, and evolutionary biology in particular. It can be done:
The Language of Science and Faith, Karl Giberson and Francis Collins
Origins: A Reformed Look at Creation, Design, and Evolution, Deborah Haarsma and Loren Haarsma
Searching for Truth with a Broken Flashlight, Michael Hawley
Beyond the Firmament, Gordon J. Glover
Only a Theory: Evolution and the Battle for America’s Soul, Kenneth Miller
The Passionate Intellect, Alister McGrath
I Love Jesus and I Accept Evolution, Denis O. Lamoureux
The Lost World of Genesis One, John Walton
