These long-lived woody plants provide shade for people, homes for animals — and help protect the planet against climate change.
Excessive groundwater use could push more than half of the regions that depend on water pumped up from underground aquifers past an environmental tipping point by 2050. That could threaten aquatic ecosystems around the world.
