The Leatherback Sea Turtle (Dermochelys coriacea) is the biggest, deepest-diving, longest traveling reptile on the planet, and has been in existence for over 100 million years - and was in existence when dinosaurs walked the Earth.

A recent NASA plane mission, termed “Operation Ice Bridge”, has discovered a huge crack forming in the Antarctic glacier. The NASA plane was able to capture detailed measurements of the glacier for the first time ever. The data that was collected from these airborne acquired measurements indicate that the Antarctic glacier is breaking up.
We all do it; drag the garbage out once a week and chuck it at the end of the curb, sometimes just one bag, sometimes more. The next morning, itʼs magically gone and our lawns look nice and tidy, problem solved! But where does it all end up? Over consumption and waste production are two huge issues in todays world.

This year, however, it’s walking amongst the living that may bring more than a few to gasp: the world’s population is projected to reach a staggering 7 billion on Halloween of this year, with another billion expected in just another 12 years: a far cry from the global population of 1.7 billion just a century ago!
In 1987, Robert Costanza from the University of Maryland (and colleagues) published a monumental paper in the scientific journal Nature, stating the value of global ecosystem services to be between $16 and 54 trillion USD/year – a benefit that isn’t accounted for in most estimates of GNP. Before taking those numbers at face value, I thought to myself – what IS an ecosystem service?
When I was in grade school, I was told that we learn about history so that we don’t repeat the same mistakes twice. Apparently, some people didn’t hear the same message, including Brazilian ranchers who are spraying one of this century’s most hazardous pesticides over the Amazon.
Think mass extinctions are just catastrophic things of the past? Think again – quick – before our species disappears.
Globalization has had many obvious, yet controversial benefits. But did you know that globalization has also led to the introduction of invasive species?
