Apples and oranges.
English as a second language, used as a global lingua franca isn’t threatening any other languages. If anything, it militates against language death by allowing both economic opportunity and the native language to coexist.
What threatens languages is primarily migration, usually due to economic reasons, that separates the generations in a region, with the younger moving off to a large city to find work. This creates a generation gap, where the grandchildren no longer learn the family’s native language. Or the reverse, when large numbers of people speaking another language, usually the official language of the country, move into a region, making the native language less useful. Another factor is official government policies that discourage speaking in other than the official languages.
The “killer” languages are proximate and vary by region. In some places, like North America and Australia, English is driving out the native languages, but in Latin America it’s Spanish and Portuguese. In central Asia, it’s Russian. In West Africa it’s French. In India it’s Hindi. Etc.
