Throughout Europe and North America, it is traditional for the bride to throw her bouquet at the reception and for all single women present to compete in catching it. The woman who catches the bouquet is said to be the next who will marry. But how did this custom originate?

The reason why whales sing has puzzled scientists and casual observers for decades. Many explanations have been offered for the vocalizations of whales, but despite many comprehensive studies, no explanation has proved conclusive.
Whether a mating call, an advanced echolocation technique, or a means of communication, whale song remains a continual mystery of the giant marine mammals, and inspires debate among scientists worldwide.

Animals migrate to reproduce, eat, or seek warmer climes. Those that migrate travel long distances in groups from one part of the world to another, past oceans, over plains, or through the sky on a decided route.
Some species must travel thousands of miles every year, while others make the trip just once in their lifetime.

Why is NOT clear cutting good for environment? |
|
|
|
|
Clearcutting, or clearfelling, is a logging practice which involves completely clearing an area of trees, regardless of their size and usability.Remaining scrub and brush are usually burnt in large burn piles that can cast a smoky haze over the area for several days.
A clearcut area may be relatively small, or may span for miles, and is often clearly visible through the air, along with the scars of logging roads cut to access it. The abrupt removal of trees can have a serious environmental impact on the surrounding area.
Negative impacts(by wikipedia)
Clearcutting can have major negative impacts. These have been cited as soil erosion, poor quality re-growth, increased risk of pest epidemics, increased wildfires, loss of biodiversity, and loss of economic sustainability and increased environmental instability, loss of carbon contributing to global warming and so on.[4] Unfortunately the response of governments around the world has sometimes been to marginalize community, environmental, social and academic concerns and defer to the logging industry.

Why flamingos stand on one leg |
|
|
|
|
Many observers have noted that flamingos and other wading birds often stand on only one leg while tucking the other leg up under the body.
Flamingos exhibit this behavior both in the wild and in captivity, suggesting that it is entirely natural, rather than the result of stress due to confinement. A number of theories have been put forward to explain this phenomenon, but ultimately no one is really sure about why flamingos stand on one leg.
