Should we eat bugs?


Do you know what Entomophagyis?
Entomophagy is the practice of eating insects - including arachnids (tarantulas) and myriapods (centipedes).



The word “entomophagy” derives from the Greek term éntomos, or éntomon, meaning, “insect(ed),” literally meaning “cut in two,” referring to an insect’s segmented body, and phăgein, “to eat.” Combined, the two terms mean, “insect eating.”
As a point of information the word itself is a rather new term. There’s no record of its coinage in the Oxford English Dictionary and its first usage to denote a human behavior may well be as recent as the 1950s.
There are no words equivalent to ‘entomophagy’ in the languages of the many ethnic groups that practice insect consumption, simply because these peoples never distinguished between insects and other varieties of food.

Why eat bugs?


Insects have served as a nutritional, tasty and safe food source for people for tens of thousands of years, all over the planet. Today insect eating is rare in the developed world, but eating insects is a common practice in over 13 countries. Insects remain a popular food in many developing regions of Central and South America, Africa, Australia and Asia. It’s only a matter of time till Eurocentric based cultures, like the United States, Canada and Europe catch on. Read more here.

Do you know what is/was the largest plant and animal

What do you thunk about this picture?



Do you know that sauropods were clearly the largest land animals that ever existed, but it has been difficult to estimate the length and mass of particular species because this has to be based on reconstructions of skeletons and soft tissue estimates.



There are some pictures of other large living beings below:


Sequoia


Blue Whale

News: Terrifying Medieval Sea Monsters. Part 1

From moviepilot.com by  ⋅ Posted on 
The seas have always terrified and beguiled mankind. Their almost endless scale, their tumultuous nature and unfathomable depths have led to countless legends and tales which have been spread around the world by those who were actually brave enough to embark across the inky, black watery abyss.
Whether it's Homeric tales of Charybdis and Scylla picking off Odysseus' men in The Odyssey, the Leviathan of Biblical lore, or modern day supposed sighting of Nessy, we've always thought there might be more going on under the waves than might meet the eye.
Early map-makers such as Abraham Ortelius certainly thought this, as he created one of the most beautiful and intriguing maps of Iceland. Around the island, labeled as 'Islandia,' is a menacing menagerie of bizarre watery beasts of unprecedented scale and ferociousness.
These monsters certainly plagued the fears of 16th century fishermen and sailors, but could there actually be some truth to these creatures? Are they merely real-life sea creatures blown out of proportion? Take a look at the pictures and descriptions and see if you can figure out the real life inspiration for the monsters. What creature are they really?
