A
cross Africa, deep beneath a host
of varied terrains, vast groundwater reserves lie almost untouched.
These aquifers are some 410,000 cubic
miles thick and contain 100 times the
freshwater that exists on the continent's
surface. As Africa's population expands,
these aquifers could prove critical in
increasing food production, reducing
poverty, and adapting to climate change.

| Summary/Abstract |
Prince of Wales Strait, Northwest Territories-A century ago, traversing the Northwest Passage was a grueling effort that often took years. Explorers frequently perished as their boats sunk or got trapped in the abundant pack ice. Today, these waters are mostly ice-free during the summer, and ships can sail through with ease.
