He warned that if the influx of newcomers doesn't slow down soon, people may be forced to sleep out on the streets.
"Our hearts are endless, but our resources are not," Adams said during an interview with FOX5 NY's Rosanna Scotto for the Fox Nation special, The Sanctuary Trap. "It's not like New York is not saying we are not a city of immigrants. We are. We have a rich history of immigrants, but we can't take the global problem and [have] it become our problem. That is unfair to New Yorkers, and is unfair to migrants."
Adams went on to address the main issue facing newcomers and residents alike: a lack of space.
