Whats the worst sin of globalization?
To hear some tell it, it’s not unfair wages or job losses, but those little tagalong critters known as invasive species. World trade has enabled flora and fauna to set up camp far from home. Consider: European hedgehogs have arrived in New Zealand, and zebra mussels from the Caspian Sea have shown up in the Caribbean. Many scientists contend that alien species wreak havoc on native ecosystems, crowding out indigenous life-forms. But another word for invasion is migration, a natural process that dates back to the moment the first clump of cells crawled out of the primordial ocean. Today, some evolutionary biologists say that the invasive-species hysteria is just pseudoscientific xenophobia and that these so-called incursions are natural selection in action. After all, the human race is one of the worst invasive species out there. Darwin would be proud. – Patrick Di Justo Mesquite This tree competes with native species for water.
