How come "-ing" was used to here? Why this sentence is starting with "forcing"?

The sentence begins with the verb "forcing" here because it connects to the previous sentence, however, this is confusing as there is a pause between them so it sounds like two separate sentences. So the full sentence should be "demand for short-term rentals like Airbnb has dropped 60 to 75 percent over the summer, forcing some owners to unload their property".
