We humans don't own the planet, nor do we own the animals that inhabit it. Animals are not ours to eat, wear or mistreat. It is our duty to live a kind, compassionate, animal cruelty free lifestyle. But more than that, we have to represent the animals.
The ambitious goal is to develop a real-world system that can capture carbon dioxide emissions before they vent into the atmosphere and then use solar energy to convert the CO2 into chemical products including biodegradable plastics, pharmaceutical drugs, and even liquid fuels.
Lead is a devastating toxin. It ravages the brain. Robs children of IQ points and brain function. And deprives our society of vast potential. It has cast a huge, destructive shadow across human civilization.
Miley seemed to fall in love with all the sights and creatures we saw, and we all had great fun learning and singing -- loudly -- some Native songs. Several times during our trip, Miley told us it was the best day of her life. For a gal who's been around the world, that's saying something.
If the U.S. Fish and Wildlife Services lists African lions as endangered, the disgraceful import of these lion trophies by American hunters should stop, denying the industry a vital class of fee-paying patrons.
Over the last year, the United States Trade Representative (USTR), desperate to reach a deal, has glossed over these concerns and attempted to paint the deal as progressive and environmentally friendly.
Now is the time to elevate engineering as key to innovation. While we can't all be Sally Ride or John Glenn, we can learn enough about engineering to thrive in our complex technological world. Let's make the Orion spacecraft, designed to take humans into deep space, a real first step toward Mars.
While the poaching and the cruel slaughter of these iconic animals primarily occurs in Africa and Asia, this is our problem as well. The illegal wildlife trade has become the world's top five transnational organized crimes.
There was a time, not so long ago, when the oyster was poor man's subsistence food, cheap, available and plentiful, and eaten more often than not because one could not afford anything else.
It is often all too easy to distance ourselves and corporate executives from the wreckage. It's clear that lack of enforcement is a problem in the U.S. and elsewhere, too. Unless we beef up government oversight, it's up to the consumers -- and we simply can't be trusted.
Beyond ecosystems, biodiversity, or economics, we have a creative and calming connection with the ocean that provides us with enormous emotional, psychological, social and spiritual benefits.
Back in 2007, a panel of scientists decided that to protect public health the national ambient air quality standard for ground-level ozone standard should be between 60 and 70 parts per billion. Last week, their recommendation was finally acted upon. But does the science still say that 70 ppb is enough?
It's easy to feel as though clean tech is an unstoppable juggernaut when you see unfathomably large clean energy targets in emerging markets like India. But the truth is, clean tech is not unstoppable.
While Easter Island is known all over the world for our giant moai statues, fewer people know that our waters contain brilliant biodiversity, with 142 species that can be found nowhere else on Earth.
If we assume a business-as-usual projection with growing populations, increasing plastic consumption and increased waste generation, by 2025, this number doubles -- we may be adding 17.5 million metric tons of plastic per year to the ocean.
