In the 1800's the Rocky Mountain West area of the USA that now includes Yellowstone National Park, was teeming with gray wolves. However they were considered nuisance predators who killed livestock and therefore, actively hunted down. By the time the National Park was established in 1827, the number of gray wolves had diminished substantially, a trend that continued thanks to a government predator control program that ensured that by 1926, there were none left.

Dandelions have long been considered a nuisance weed by most gardeners. However they, along with the rest of the world, may soon start treating the annoying plant with the respect it deserves. That's because the white milky sap of their taproot contains particles of rubber of such superior quality, that Dutch biologist Ingrid van der Meer, refers to dandelions as the future of road transport.
Death Valley National Park in California's Mojave Desert is known for many things - Its extreme temperatures, varied altitude that ranges from 282ft. below sea level to 11,000ft. above, beautiful rugged terrain and most of all, 'rolling' or 'dancing' stones. The phenomenon whereby large boulders, some weighing as much as 500 lbs, move several hundred yards in a straight line or zigzag patterns, has confounded experts for years.

What do Lil Bub, Princess Monster Truck, and Venus the Two-Faced Cat have in common with tigers? They are all kittycats! That is why when Greenpeace was looking for a way to spread the word about the rapidly dwindling population of tigers in the wild, they turned to these celebrities for assistance.
Mention Hawaii and the first thing that comes to mind are the pristine beaches. What is not as well known is that Hawaii's Big Island is also home to some of the world's most active volcanoes, including the spectacular Kilauea! While the dynamic volcano has been erupting almost nonstop since 1983, some years, the amount of magma coughed up is larger than others.
Scientists have long suspected that there is water trapped deep inside the Earth's interior. However, they had never been able to verify it. Hence geologists had no choice but to adopt the theory that the water in our oceans was deposited by icy comets hitting the forming planet. Now thanks to evidence uncovered by Associate Professor Steven Jacobsen of Northwestern University and seismologist Brandon Schmandt from the University of New Mexico, there is finally proof that our oceans may have emerged from a massive reserve that lies 400 miles beneath the Earth's crust.
Though most people believe that climate change is real and likely to result in some catastrophic events if allowed to continue unabated, very few are ready to make the lifestyle changes needed to turn things around. That's why Italian adventurer Alex Bellini has come up with the radical idea of living atop an iceberg, until it melts. He believes that witnessing something this dramatic may be the key to convincing more people to take action.
While most people are curious about how Earth was formed and more importantly, how it transformed into this habitable paradise, very few, have the patience to pore over complicated science books to find out. Now, thanks to this amazing video created by Germany's Kurzgesagt, our beautiful planet's entire history can be mastered in about seven minutes!
