There's a headline news article today here in the UK announcing that the UK is no longer a majority Christian country.

Some part of this is due to a growth in other religions caused by immigration and their differential birth rates but the real cause is Christians no longer believing in Christianity.
This is mirrored across the Western world:
While most countries in the Western world were historically almost exclusively Christian, the post-World War II era has seen developed countries with modern, secular educational facilities shifting towards post-Christian, secular, globalized, multicultural and multifaith societies. While Christianity is currently the predominant religion in Latin America, Europe, Canada and the United States, the religion is declining in many of these areas, including Western Europe, some countries of North America (including the United States), and some countries in Oceania. A decline in Christianity among countries in Latin America's Southern Cone (in particular Chile and Uraguay) has also contributed to a rise in irreligion in Latin America.

As an atheist, I think that this is excellent news, the fewer people wasting their time and resources worshipping non-existent gods the better.
(And btw, as criminality is also declining, there is no associated decline in moral values; who knew!)
But do we have anything to lose?

"Science adjusts it's views based on what's observed.
Faith is the denial of observation so that Belief can be preserved."
