Japanese Language on the Verge of Demise

Recently, many japanese people are talking about a book titled '日本語が亡びるとき'. Its English might be 'Japanese Language on the Verge of Demise' or 'Japanese Language in Crisis'. 

Anyway, it shows our fear that English cannot be a true native language for most of the Japanese people, but the world has been changing toward the direction in which everything, that includes business, technologies, and also cultures, will be talked in English. I haven't yet received this book from Amazon, so I'd like to wait for a moment before discussing this problem in detail.
