The population is increasing very fast
We use the present continuous when we talk about changes happening around now - so this sentence should be correct.
But what if I say this?
The population increases every day
I can't use present continuous, right? Because of "every day"
This week I am having a lot of work
This week I have a lot of work
Even though we are talking about a permanent situation, the verb to have is non-progressive in this case so we should use the present simple, right? But I have seen a lot of sentences such as
"I am having a party today"
The verb have is non-progressive in this sentence so why people tend to use the present continuous?
