World Environment Day (WED) is a day that stimulates awareness of the environment and enhances political attention and public action. It is on 5 June.

The first World Environment Day was on 1973. World Environment Day is hosted every year by a different city with a different theme and is commemorated with an international exposition on the week that 5 June is on. World Environment Day is in summer in the Northern Hemisphere and winter in the Southern Hemisphere .

There is nothing late, atleast now everyone must take CARE towards Environment and try to protect environment in many different ways at their possibility. Every individual had the right on this planet, so everyone is responsible even for distruction or to protect from environmental pollutions. Even a single member in a family must be aware of these environmental pollutions and he need to take initiative and make the other members to do their part to save the environment. SAVE this Beautiful Environment and we need to gift it to our Future Generations. Atleast START thinking from now.

Hope my blog will help atleast to some extent and i will be contributing my part to this planet by this.

Cities in 92 countries around the world prepare to shut off their lights for one hour today in observance of Earth Hour, an annual event geared at showing support for taking action on climate change issues.

During Earth Hour, people around the world are asked to turn off their lights for an hour at 8:30 p.m. local time on March 27. This year the event has topped its participation figure from last year, which was 88 countries.

Countries and regions involved for the first time include: the world’s newest country Kosovo, the remote island nation of Madagascar, Nepal, Saudi Arabia, Mongolia, Cambodia, Czech Republic, Paraguay, Ecuador and the U.S. Commonwealth of the Northern Marina Islands in the Pacific Ocean.

Earth Hour global organizers confirm there are currently more than 1,100 cities and towns signed up to switch their lights off on Sunday evening, 100 more than last year. Among the iconic landmarks in cities taking place are the Tokyo Tower in Tokyo and Berlin’s Brandenburg Gate.

“Earth Hour demonstrates the determination of the world’s citizens for a better, healthier world,” . “It brings together cities, communities, businesses and individuals on the journey to positive action on climate change.”

Earth Hour is an initiative by the non-profit environmental group WWF. The event began in Sydney in 2007, when 2 million people switched off their lights.

In 2008, more than 50 million people around the globe participated. In 2009, hundreds of millions of people in more than 4,000 cities and towns switched off their lights for one hour.

Importance of Adequate Water

When faced with a survival situation, clean drinkable water is often the most important consideration. People have survived without food for weeks or even months, but go without water for even just one day and the survivor will be in desperate straights indeed.

Knowing that water is by far the most important nutrient for the human body (besides oxygen) and, in particular, during a survival situation when finding potable water may not be easy, the question becomes - just how long can the human body survive without adequate water?

To maintain a high level of health and efficiency even in ideal environments, a minimum of two quarts of clean water per day per person is the generally accepted rule of thumb. In very hot or cold or very dry environments, or if you are physically active, two quarts of water a day may not be enough to sustain life over a period of days or weeks.

Water lost through sweating and normal respiration must be replaced in order to stay healthy and function at top efficiency. Water is also needed to process the food you eat, especially if it is salty or you eat heavy foods like meat.

Environment and Water Needs

In general the higher the temperature the greater your water consumption needs to be. If you are active or exposed to the hot rays of the sun you may need upwards of a gallon of water per day to stay to healthy.

Perhaps surprisingly, very cold environments can be as dry as the driest desert. This is because cold air cannot hold much moisture. This cold dry air serves to dehydrate your body with every breath you take. Cold dry air can also rob your body of moisture via loss from exposed skin. This is one reason why your lips may be prone to chapping. So during cold weather even though you may not be sweating nearly as much as when you are in a hot environment you may still easily become severely dehydrated without even realizing the danger you are in.

Wind can also play a role in the amount of water you need to take in. A dry wind on exposed flesh can suck the water right out of a person. Indeed, the remains of mummified animals and even people are often found in desert regions, their bodies totally dried out.

Effects of Going Without Water

Although two thirds of the human body by weight is composed of water, this water is needed for circulation and other bodily processes including respiration and converting food to energy. If you are losing more water than you are taking in, dehydration will occur.

It has been shown that if you lose just 2.5% of your body weight from water loss, you will loose 25% of your efficiency. For a 175 pound man that is only about two quarts of water. As the survivor dehydrates, his blood becomes thicker and loses volume. This causes the heart to work harder and circulation of blood to be less efficient. In a survival situation, loosing a full one quarter of your physical and mental abilities due to dehydration could mean the end of your life. Bottom line: drink plenty of fluids whether you feel thirsty or not so that you stay a peak efficency.

Survival Times without Water

Ill health, exposure to the elements, shock, and panic can reduce your survival time in any situation. An important additional consideration is whether or not to eat food when there may be an inadequate supply of water. Certainly foods that contain a high proportion of water, such many kinds of fuits and berries may actually aid the survivor in providing water. Meat, dry and salty foods should be avoided as they require water from your body for processing and will serve to dehydrate you further.

The survivor who is in good health, who uses his head, and rations whatever water is at hand may expect to be able to survive according to the following chart. Of course, there are many factors to be considered so your mileage may vary:

Recovering From Dehydration

The good news is you can lose as much as 10% of your body weight through dehydration and suffer no long term ill effects. Simply by drinking several quarts of water you will be restored in a very short time. However, a survivor who has lost this much water from his body will probably not be in a position to find water.

In cool temperatures, a loss of 25% of your body weight in water will probably be be the end. If the temperature is over 90 degrees farhanheight then you may not make it even at the 15% dehydration level.
