A student I volunteer with started his essay in the following way:
For solving this problem we need to do more recycling.
I corrected him as follows:
To solve this problem we need to do more recycling.
This form (to solve) sounds more direct and natural to me.
I know that you can use for solving in other contexts, but it doesn't sound right at the beginning of a sentence.
I'm wondering if I was right to correct him and if so is there a technical or grammatical reason why for solving is less acceptable or is it just my bias?
