Dictionary

Encyclopedia
Turtles are reptiles of the order Testudines (or Chelonii) characterised by a special bony or cartilaginous shell developed from their ribs and acting as a shield. The order Testudines includes both extant (living) and extinct species. The earliest known members of this group date from 157 million years ago, making turtles one of the oldest reptile groups and a more ancient group than snakes or crocodilians. Of the 327 known species alive today, some are highly endangered.
Turtles are ectotherms—animals commonly called cold-blooded—meaning that their internal temperature varies according to the ambient environment. However, because of their high metabolic rate, leatherback sea turtles have a body temperature that is noticeably higher than that of the surrounding water.
Turtles are classified as amniotes, along with other reptiles, birds, and mammals. Like other amniotes, turtles breathe air and do not lay eggs underwater, although many species live in or around water. — Wikipedia

Banning plastic bags, town by town: A guide
on February 20, 2019 at 3:24 pm
Since plastic carryout bags were introduced in the 1960s, people have used trillions of them, and, for the most part, thrown them away. And whether they're sitting in a landfill, hung up in a tree limb or floating around the ocean, the bags don't biodegrade, and they're not going away anytime soon. They're free to consumers, convenient and cheap for stores to use. But they have joined billions of tons of tossed-away plastic packaging materials and products to cause a variety of environmental […]
