Humans are an infant species, a mere 150,000 years old. But, armed with a massive brain, we've not only survived, we've used our wits to adapt to and flourish in habitats as varied as deserts, Arctic tundra, tropical rainforests, wetlands and high mountain ranges.
During my training to become an airline captain, I had to learn how to navigate an airplane over long distances. Flights over huge oceans, crossing extensive deserts, and connecting continents need careful planning to ensure a safe arrival at the planned destination.
Food deserts on Chicago's South Side have shrunk some since 2006, and this has provided health benefits to the communities.
Having lived in the arid deserts of Southern California since the 1970s, my interest in water conservation is a very personal concern. Water! The source of life! Some people are squandering the world's most precious resource while others have too little clean water to drink.
Opening up Atlantic and Arctic waters to drilling would lock the next generation into burning oil and gas in a way that only makes climate change that much worse, fueling ever rising seas, widening deserts, withering drought, blistering heat, raging storms, wildfires, floods and other hallmarks of climate chaos.
Places that have become agricultural deserts, trashed by giant corporations, could be reforested, drawing carbon dioxide from the air on a vast scale. The ecosystems of land and sea could recover, not just in pockets but across great tracts of the planet.
Official education was telling people almost nothing of the nature of all those things on the seashores, and in the redwood forests, in the deserts and in the plains.
From space, the earth appears predominantly blue; the clouds are brilliant white. Surprisingly, you don't see much green, although Ireland looks green, and so do Scandinavia and New Zealand. The deserts are brick red and really stand out.
Human civilization has been changing the Earth's environment for millennia, often to our detriment. Dams, deforestation and urbanization can alter water cycles and wind patterns, occasionally triggering droughts or even creating deserts.
I'm conflicted because I like being in deserts. I find them sort of cleansing, but there's another part of me that hates dust. And I particularly hate dust in cars, so it's a huge conflict going on there.
