Answer:
In recent years, many Arab and African migrants have braved the waters of the Mediterranean to find a better life in southern European countries like Spain. According to the article, the migration of people from Africa affected Spain socially, economically, and politically. We know the migration has affected Spain socialy when the article mentions " 'I think some people are scared. Like, when you see a big Moroccan guy or a big African guy, usually you think: ‘I’m going to cross the street. I don’t want to walk in the same street. Maybe he jumps me, attacks me, robs me,’” says Kunal Keswani, a 16-year-old student attending the Stop Rumors seminar. “People have that concept of them — and not just a small percentage of people. It’s a big percentage actually — many people are racist' ". The migration affected Spain economically because Spain spent a large sum of money to build a fence to keep out migrants. "Spain has spent more than $270 million fortifying its borders in the past five years." “You know how many lives I could save and improve, with that money?” Cortina asks. “If I only had the budget they use to put up fences — we could really change things.” The migration affected Spain politically because "If migrants do manage to get here, the government houses them in prison-like facilities — which creates a stigma, says Cortina, the NGO director."
