Pet Bottle: Different Kinds and Facts!

The FACTS of it........

·  The PET bottle was patented in 1973 by chemist Nathaniel Wyeth (brother of distinguished American painter Andrew Wyeth).
·  The first PET bottle was recycled in 1977.
·  An estimated 7,700 curbside collection programs and 10,000 drop-off programs collect PET plastic in the United States, currently.
·  Approximate number of PET beverage bottles per pound:
16 oz. -- 18 bottles per pound
20 oz. -- 19 bottles per pound
1 liter -- 12 bottles per pound
2 liter -- 9 bottles per pound
3 liter -- 5 bottles per pound
·  Cubic yards conserved in a landfill by recycling PET beverage bottles:
4,800 recycled 16-ounce bottles saves a cubic yard
4,050 recycled 20-ounce bottles saves a cubic yard
3,240 recycled 1-liter bottles saves a cubic yard
2,430 recycled 2-liter bottles saves a cubic yard
1,350 recycled 3-liter bottles saves a cubic yard
·  Since 1978, manufacturers have reduced the weight of a two-liter bottle by about 29%, from 68 grams to 48 grams.
·  Recycling a ton of PET containers saves 7.4 cubic yards of landfill space.
·  According to the EPA, recycling a pound of PET saves approximately 12,000 BTU's. (To see our April 2010 Life Cycle Inventory Report, visit our Sustainability page.) 
·  The average household generated 42 pounds of PET plastic bottles in the year 2005.
·  Custom bottles (which are bottles used for products other than carbonated soft drinks) represent 62% of all PET bottles available for recycling.
·  Nineteen 20 oz. PET bottles yield enough fiber for an extra large T-shirt, or enough to make one square foot of carpet.
·  It takes 63 20 oz. PET bottles to make a sweater.
·  Fourteen 20 oz. PET bottles yield enough fiberfill for a ski jacket.
·  It takes 114 20 oz. PET bottles to make enough fiberfill for a sleeping bag.

Banana: The good thing!

Any of several tropical and subtropical treelike herbs of the genus Musa having a terminal crown of large entire leaves and usually bearing hanging clusters of elongated fruits
Classified under:
Nouns denoting plants

Fruit of the genus Musa (family Musaceae), a gigantic herbaceous plant spread by rhizomes, and one of the most important food crops of the world. The banana is consumed extensively throughout the tropics, where it is grown, and is also valued in the temperate zone for its flavour, nutritional value, and constant availability. Hundreds of varieties are cultivated. Perhaps the most important species is the common banana, M. sapientum. The ripe fruit is high in carbohydrates (mainly sugar), potassium, and vitamins C and A, and it is low in protein and fat. Though usually eaten fresh, bananas may also be cooked. The U.S. imports more bananas than does any other country. See also plantain.

Osprey: Its Meaning?

MEASUREMENTS: The Osprey has a body length of 21 - 24 inches, a 5 - 6 foot wingspan, and weighs 2 1/2 - 4 1/2 pounds.
HABITAT: The Osprey lives throughout the world near bodies of water, like lakes, rivers, marshes, mangroves, and seashores.

DIET: An Osprey’s diet is almost exclusively live fish, and includes a wide variety of fish species. The Osprey uses low, slow flights over water, and occasionally hovers to search for prey. When a fish is spotted, Osprey make dramatic dives from heights of 30 - 120 feet to plunge feet first into the water after their prey. 

REPRODUCTION: The nest is made of sticks and other material in trees, on cliffs, on man-made structures like power poles, bridges, buoys, and elevated platforms, or on the ground. The female lays 2 - 4 eggs that are incubated for 35 - 40 days. The chicks tend to hatch sequentially, 1 - 5 days apart. The young fledge at about 7 - 8 weeks of age, but are usually dependant on the parents until the fall migration. Ospreys become sexually mature at about 3 years of age.
NAME DERIVATION: The scientific name comes from the mythical king of Athens, Pandion, whose daughters were turned into birds, and the Greek words halos, which refers to the sea, and aetos, meaning an eagle. The common name is from the Latin word ossifragus, meaning "a bone breaker." Ospreys have also been called Sea Hawks and Fish Hawks.
  • Unlike Bald Eagles, an Osprey can become completely submerged during its dive into the water and still be able to fly away with its prey. Bald Eagles are usually limited to plucking fish at the surface of the water as they fly by.
  • Ospreys have an opposable toe that can face forward or backward. While the bird is perched, it usually has three toes in front and one in back. When an Osprey catches a fish, its feet and toes are positioned with two toes on either side of the fish, one foot ahead of the other. The head of the fish faces forward in a streamlined position for transport through the air.

What is Purified Water?

Purified water refers to all types of water from which chemicals are removed via a variety of different processes. The simplest of these processes are available to consumers with water filters that help sort out some of the chemical compounds found in tap water. Other more expensive filters use a reverse osmosis technique, which helps shunt chemicals in the water to the side while leaving the remaining water free of most commonly found chemicals. Distilled water and deionized water are also considered purified. 

Distillation of water generally means boiling the water so that any chemicals present are separated in the process. As water steam or vapor rise from a boiling batch, it is captured in tubes and allowed to cool back down to liquid state. Such a process can remove many chemicals from water, since they won’t turn into a vapor state. Often, water is double distilled.

How important is WATER ?

Water is very important for life. We need water to drink, to wash our hands, to cook, to water plants and many other things. What other important uses for water do we have?
Without water, the plants would die and people and animals would go thirsty.
Did you ever wonder why water was so important? Do you know why water is water? 

Let's take a closer look at water...
Your body is made up of many bones. All these bones make up your skeleton. 

When you get out of a pool, did you ever wonder where the water on your body goes as you begin to dry? 
The water on your body changes to a gas called water vapor. Water turns into a gas through a process called evaporation. Heat makes water evaporate faster. 

All air has some water vapor. Tropical rain forests and deserts are both hot. One is drier than the other. Where will water evaporate faster- in the rainforest or in the desert? Click on the picture that matches your answer.
Water evaporates faster with moving air. Warm, fast moving air makes water evaporate faster. These wet clothes are drying in the warm wind.

What happens to water vapor if it is in a cool place?

Water vapor may condense to liquid water as it cools. This is what happe ned to the water vapor from your mouth as it touched the mirror. The mirror was cold and so the water turned back into water droplets. Condense is the opposite of evaporate. 

Dew is a form of condensed water vapor. You can see dew in the morning on your lawn. Water droplets formed overnite as it became cooler.
Frost may form as the air gets colder. You may have seen frost on the windshield of your car and your mom and dad scraping it off. Frost is ice crystals that form on objects. Look at the frost on this pine cone.
