What Happens in Space Matters on Earth

Solar activity and planetary changes have repeatedly shaped human history in unexpected ways. Beginning in the 14th century, reduced solar activity combined with volcanic eruptions caused global cooling that destabilized empires through harvest failures. Space scientists studying Venus's atmosphere discovered that CFCs were destroying Earth's ozone layer, leading to their global ban, while research on Martian dust storms revealed that nuclear war could trigger catastrophic cooling. As humanity enters a new space age focused on resource extraction, we need cosmic environmentalism that prioritizes Earth's needs.
