It’s one of the oldest existing lifeforms on the planet—blue-green algae. Treating bodies of water affected by “harmful algae blooms” or HABs, is an all-encompassing water treatment challenge, one that begins by understanding the opportunistic nature of these organisms and the constant nature of their threat to water quality, from pools to ponds to the world’s largest lakes.

For the millions of homeowners with swimming pools, water conservation means rethinking how they manage one of their property's most water-intensive features. The good news? One of the most effective solutions is already well-established—the automatic pool cover.

New research reveals that fog is far more than suspended water droplets. It is a temporary aquatic world filled with microbial life that may help cleanse the atmosphere, influence climate, and even affect human health. In a very real way, fog is, in fact, alive!

Far below the surface of the Atlantic Ocean, beyond the reach of wind and waves, a vast and patient machinery is at work. It does not roar or churn in ways we can easily see, yet it moves heat, salt, carbon, and life itself across the southern and northern hemispheres. Known as the Atlantic Meridional Overturning Circulation, or AMOC, it is one of Earth’s most consequential natural systems. It is also one of its most vulnerable.

At first glance, the California Aqueduct can seem almost unassuming, but in truth, it is one of the most ambitious and consequential feats of hydraulic engineering ever attempted in the United States — nothing less than a modern-day river sculpted from concrete and willpower, delivering life-sustaining water to millions of people and acres of farmland in an otherwise arid landscape.

Preventable, yet tragic on a global scale, unsafe water, poor sanitation, and lack of hygiene kill millions each year—more than all acts of violence combined. Tracing the history of water treatment and today’s waterborne-disease crisis, calls for renewed commitment to clean water as humanity’s most essential defense.
