Ethnic groups in Asia

There are an abundance of ethnic groups throughout Asia, with adaptations to the climate zones of Asia, which can be Arctic, subarctic, temperate, subtropical or tropical. The ethnic groups have adapted to mountains, deserts, grasslands, and forests. On the coasts of Asia, the ethnic groups have adopted various methods of harvest and transport. Some groups are primarily hunter-gatherers, some practice transhumance (nomadic lifestyle), others have been agrarian/rural for millennia and others are becoming industrial/urban. Some groups/countries of Asia are completely urban (Singapore and Hong Kong). The colonization of Asia was largely ended in the twentieth century, with national drives for independence and self-determination across the continent.
