“Earth's Final Hour!”

In "Earth's Final Hour!", the Justice League of America faces a chilling threat when industrialist Theo Zappa begins draining Earth's plankton to fuel a desperate trade with the ecologically ruined planet Kalyarna. With Aquaman sounding the alarm, the League divides into teams to stop Zappa’s plan before it triggers mass starvation—before the planet’s delicate balance collapses. Written by Mike Friedrich and Dennis O'Neil, with dynamic art by Dick Dillin and Joe Giella, and a striking cover by Neal Adams, this 1970 issue delivers a timely, high-stakes crisis with the fate of Earth hanging in the balance.
