They have also increased outside the EU. So leaving will make little/no difference.
The question (which is impossible to answer with any degree of certainty) is whether they would have increased more/faster had we not been in the EU than they did with us in the EU.
It may make no difference to the fact that there is an increase regardless, but the rate/magnitude of increase is very important.
I'd really like to agree but since the EU has existed these things have increased so why should we believe that will change?
