Cleaner But Greener

The National Aquarium

If your household is like most, you’ve likely accumulated an array of scrubs, sprays, paints and solvents, each aimed at helping you tackle a dirty job. But what if having a squeaky clean bathtub leads to tainted ground water, or a shiny car in the driveway means fewer fish in the creek? As with so much in our lives, some of these choices are…complicated.

The National Aquarium

If you’ve ever peered into a tide pool and glimpsed an exotic, pulsing flower-like creature, you’ve probably seen a sea anemone. Found across the globe, these diverse and beautiful creatures aren’t plants, they’re colonizing animals, and they occur in nearly every marine habitat—tropical, temperate, shallow or deep. And they’re even here in Baltimore’s Inner Harbor.

This is a re-broadcast.

Many people seem confused about climate change, perhaps because of a fundamental misunderstanding of the difference between weather and climate. Let’s get our facts straight!

Many of us try to minimize our impact on the environment by buying local food and low-emission vehicles, but what about with our clothing choices? 

Your clothes might be sources of ocean and plastic pollution unless you take a few steps to prevent it. John tells us how to do that. 

It’s consistently astonishing to me how much of an impact we humans have on our native species. Our decisions to develop and farm lands, level forests, and hunt can have a wide-reaching impact on plants and animals alike. This is especially true for the top predators, who rely on a finely-tuned natural web of other species to survive.

For nearly 40 years, the Marine Mammal Protection Act has kept dolphins, whales, polar bears, sea otters and other species safe along American coastlines. However, this protective order is now more endangered than any animal it protects. Listen in to learn more.

When most of us think of volcanoes, we think of mountains, rising and looming over flat plateaus. Cone-shaped and spewing burning ash and molten rock in flows of hot orange-red rock. Washington State's St. Helen's and Italy's Mount Vesuvius are famous volcanic explosions. 

And of course, the Hawaiian Islands-you can take a helicopter ride right over the smoking and steaming new coastline.  

It’s unusual for people to have an incredible sense of smell. In the perfume industry, these people are called "noses." But in reality, you don't smell with your nose, you smell with your brain. Our sense of smell increases until we’re about eight years old, then plateaus and declines as we age. Yet even the best "noses" pale in comparison to others in the Animal Kingdom.

Any guess as to whose sense of smell is among the best? Is it the bloodhound? The truffle-hunting pig? The answer may surprise you. To find out, you're going to have to leave the land, grab your scuba gear and get in the water, for the holder of this distinction is the shark, the bloodhound of the sea.
