will vs could. (a nitpicking session)
You say: "(...) in just 30 years, it is estimated that one fourth of the worlds' mammals will no longer exist.(...)"
Actually, the article doesn't say that it will no longer exist, it says, "(...) an equal number predicted that up to one-fifth of all living species could disappear within 30 years. (...)"
So, who knows, they could but maybe they won't.... maybe but it's OK to dismantle the Clinton wild spaces initiatives. Hey, them biologist may be all libruls too... :-) (Maybe their just helping out with propaganda (?))
