No country buys more sneakers than the United States

No country buys more sneakers than the United States,where people purchase 3 pairs a year on average.To meet this demand, roughly 23 billion shoes are produced each year,mostly in factories across China and Southeast Asia.But making shoes has become more complicated, more labor-intensive,and in some ways, more dangerous,for the workers involved and for our planet.Shoe manufacturing accounts for roughly one-fifth of the fashion industry carbon emissions.
