In his new book The Journeys of Trees，science writer Zach St.George explores an extremely slow migration，as forests creep inch by inch to more pleasant places. “The migration of a forest is just many trees sprouting(发芽)in the same direction，”St.George writes.“Through the fossils that ancient forests left behind，scientists can track their movement over thousands of years.They move back and forth across continents，sometimes following the same route more than once，like migrating birds or whales.” This has happened over thousands of years，and climate change tends to be the driving force. Of course，today，climate change is speeding up，and trees can't keep pace.Take California for example，it's getting hotter and drier and scientists estimate that before too long，Sequoia National Park may not be able to keep giant sequoias (巨杉). “The scientists there had never seen anything like it，”St.George says.“They worried，and I think at some point we will lose these ancient trees and that we will have to think about what we do with the places，and whether we should plant new groves where they are easy to grow.” This is known as “assisted migration”—humans planting trees in other places where they're more likely to flourish．But this process carries risks—people can accidentally introduce insects and diseases to new places，where they may wipe out entire native populations.So，St.George writes，there's a debate among conservationists and foresters today：Should humans help the trees escape? “There may be cases where people are probably going to step in and help species move to places where they'll be more suitable in the future，”St.George says.“So far，there are no huge movements of citizen groups moving trees north.But that is kind of one vision of the future that the people I
