The two questions I am about to pose might be stupid (should there be a comma here, by the way?) but I checked and rechecked the rules and still can´t wrap my mind around it. Maybe there are several ways to do this!
This is what I am wondering about (The first sentence is for the sake of context):
For instance, when a large field of rapeseed withers, bees can’t find food in this area anymore. As a result, a lot of beekeepers have to feed their bees from June until the next year’s spring.
What are the consequences of the/a decrease of bees?
In the first sentence I wrote, "the next year's spring" but then I had second thoughts about. Sure, it's this very spring, but it is always next year's spring when June is the starting point in the year before. Should it be omitted?
In the second sentence, I started out with, "a" since I had heard something like that many times before. But shouldn't it be, "the" since it is a specific kind of decrease?!
Maybe I am thinking too much?
