Far be it from me to defend this drivel but, it could be the writer means each year the count is down 1% from the year before - a geometric progression that does not end in zero - kinda like walking half way to the wall with each step.
But a projection like this requires that you accurately measure the phytowhaterver count every year. To my knowledge, there was not/is not a yearly plankton census commencing in 1912.
These people are so unhappy when the sky isn’t falling.
What a dismal life.
1% a year for a hundred years equals damn near gone.

So, you picked number 2....
