No, restricting immigration does little to control population increase in global terms. It just builds pressure along our borders and means more expense and more annoyance any time you try to cross them. Aren't our borders obnoxious enough already? Scan your travel documents, put all your precious goods in this tray while we put it in a conveyor and leave it lying around for anyone to pick up, take off your belt, take off your shoes, stand there with your arms up while we take a picture of you naked, give me your passport, take off your glasses, look into that camera (what do you mean you can't see where the camera is without your glasses?), who are you, where are you going and why?
Also, there's a range of opinions on whether peak population is coming sooner/lower than the UN headline prediction.
http://www.bbc.co.uk/news/magazine-24303537 but one of the things that reduces population growth is better education and access to healthcare (including understanding of and access to contraception), which is often funded by UK overseas development money... oh and which party wants to cut that? UKIP, yet again saying one thing but having policy that does another.
It's not just transport where UKIP makes no sense at the minute
