Every day 37,000 people leave their homes and join the 258 million migrants who live in a different country from where they were born (1, 2). And experts believe that the number of migrants will continue to grow. Climate change alone is expected to force 200 million people to leave their homeland by the year 2050 (3), and some expect the number to reach 1 billion by the year 2100 (4, 5). Routinely, we hear that these numbers are unprecedented, that this level of migration is unsustainable, and that these migrants threaten our way of life. Are these claims right?

观点：要了解迁移如何影响人的安全，请回顾过去。

每天3.7万人离开自己的家园，并加入258万个移民谁住在不同的国家，从他们出生（1，2）。而且专家认为，移民人数将继续增长。单独气候变化可能迫使两亿人2050年（离开故土3），并且有人预计数2100年（达到10十亿4，5）。通常，我们听到这些数字是前所未有的，这种迁移水平是不可持续的，而且这些移民威胁着我们的生活方式。这些主张正确吗？
