Bird-Watchers Flock To Florida Beaches
There’s now another good reason a growing number of bird-watchers are flying toward Florida beaches. The newly opened south loop of the Great Florida Birding Trail brings 116 sites across south Florida into the 2,000-mile highway trail designed to conserve and enhance bird habitat by promoting bird-watching activities and conservation education.
With more than 300 species of birds visiting or living along The Beaches of Fort Myers & Sanibel, visitors come from all over the world to explore sites along the shoreline, shallow mud flats, inland waters, back bays and forests. Birds are so prevalent in the area, it’s been named the top bird-watching destination in the U.S. by USA Today. Bird-watchers can spot egrets, wood storks, ibis and herons of every description and color. Rarities such as limpkins and reddish egrets may also be seen, as well as birds of prey such as red-shouldered hawks, bald eagles and osprey.
Mark Kiser of the Florida Fish and Wildlife Conservation Commission serves as birding trail coordinator. The Florida Birding Trail program identifies interesting sites for bird-watchers in a Birding Trail guide available, free, at the Audubon Corkscrew Swamp Sanctuary or www.floridabirdingtrail.com.
Corkscrew Swamp Sanctuary was selected as a premier or “gateway” site because of its extensive services for visitors, from a 2.25-mile boardwalk, to state-of-the-art Blair Audubon Center and a variety of educational activities, as well as more than 200 species of birds, including the largest nesting colony of endangered wood storks. The area encompasses more than 13,000 acres of natural habitats; there’s even the largest stand of old-growth bald cypress trees.
Birds – The Peregrine Falcon
The peregrine falcon is the best known falcon and most widespread in the world. However if you travel to North Dakota, you won’t see many and you will not find any at all in Antarctica.
This falcon was on the endangered species list back in 1970 because of a problem with egg shell thinning that was caused mainly by use of the pesticide DDT during the 1950s and 60s. It took biologists 20 years to figure out that the pesticide used to protect plants from insects was the problem affecting these birds and other animals. Small animals ate the plants contaminated with the pesticide, and when the peregrine falcon hunted those animals, the infected flesh poisoned them. The chemical even changed the behavior of peregrine falcons in that it made them stop caring for their young.
The federal government banned the use of DDT in the United States; however, the recovery process took a while because the chemical residue remained in the environment. Other countries which are home to peregrine falcons still use DDT, and that, along with trapping and shooting by poachers, still cause the bird’s population to decrease. Today the endangered list still includes the peregrine falcon, and they are gradually increasing in population.
The peregrine falcon is not a very large bird; it is about the size of a crow. It is identifiable by its dark blue to slate colored back and its white throat. It also has a black teardrop right under its eye, and small black sideburns.
Peregrine falcons hunt at dawn and dusk; they will prey on ducks, pigeons, other birds and small mammals. They search for their prey from the air, and when they spot something to eat, they attack, making a sharp loud territorial call. They will swoop down at an incredible speed, up to 200 miles per hour, which makes this the fastest creature on earth. When they target their prey falcons use their talons to strike a severe blow to the creature to eat on the spot or to carry away to their eyrie.
Peregrine falcons are normally cliff dwellers which build their nests far out of reach of people. However, you can find some in cities on top of high buildings. Researchers who study these birds help them with city nesting; they supply certain buildings with leaves and other materials which the falcons can use.
The peregrine falcon can be found all over the world. Just look out for a bird the size of a crow with dark sideburns, yellow legs and pointed wings when in flight. Hunting permitted with a camera only.
Rolex GMT- master replica
The Rolex watches have been called the king of the sea. The Rolex watches have also been called the king of the air. The Rolex watches are also truly King over all the fashion accessories in this world. Think of a watch that can probably beat the Rolex watch at its own game. You will probably think hard and long and at the end of the day you will conclude that the Rolex watch is truly on top of the game.
One such Rolex watch that also carries the mantle of being the unchallenged king of the air is the Rolex GMT- master. The GMT master has been used by pilots for over 100 years and it has explored the skies and the continents like no other watch. This watch was launched in 1954 and was the first watch to show the time in two time zones. Later the GMT I was improved into the GMT II which has the capability to show the time of three time zones. These watches are also amazingly water resistant. However these watches are expensive. Alternatively, one should opt for the high quality and affordably available Rolex GMT- master replica.
This replica is by all means an exact duplicate of the original GMT. It comes with a sapphire crystal scratch resistant glass and also with Japan made top quality automatic movements that make this replica not just accurate but highly precise. The Rolex replica GMT also has a body made of heavy construction that makes this watch highly durable and long lasting. Additionally this watch is highly water resistant, resistant to rain water but is not made for diving.
The Rolex GMT- master replica is the perfect gift for anyone who appreciates first rated accuracy and precision of a watch and also watches elegancy, yet at the same time not having the cash to purchase the original GMT.
Biomass: Heating Your Home With…Corn?
With fossil fuel prices expected to continue increasing, many people are nervous about future heating bills. Using biomass as an alternative is becoming particularly popular. As strange as it may sound, corn is a popular fuel.
Not Just For Movies Anymore
As mentioned by President Bush in his State of the Union speech, the United States has a bad oil addiction. Throw in the negative environmental impact of using fossil fuels, and it becomes apparent a change is needed. As we look around for alternative energy sources, biomass is becoming a popular choice. Biomass is simply energy derived from the burning of bio fuels such as animal waste and excessive crops.
As people starve around the world, it is sadly ironic that we have a major surplus of corn. Corn makes an excellent biomass power source. This is because corn packs a serious amount of energy in each kernel. When used with a heating system, they produce as much heat as traditional furnaces, but at a much lower cost.
Biomass corn energy is produced using dry shelled corn as the power source. Unlike the edible variety, the corn does not have to be of high quality stock. Pretty much any shelled corn will do so long as it is dry and free of husk fibers.
Corn is turned into heat for a home much the same way as wood. The process involves a fired stove with corn being used instead of wood. If you’re picturing standing in the snow with a shovel, you will be happily disappointed. These days, shelled corn is delivered to your home where it is stored in a tank. As the heating system requires additional fuel, a thermostat senses the loss in temperature and opens a door in the storage tank. A pre-set amount of corn falls into the furnace and, ta da, you have more fire and more heat. The heat is then piped into the home through the same duct system used with an electric heating system.
Generally, burning corn for heat will cost you half as much as oil produced energy, 30 percent less than coal produced heat and 70 percent less than heat produced with natural gas. If you’re buying energy to heat your house from a utility company, converting to a corn can save you as much as 75 percent.
At first mention, using corn as a fuel source might seem “out there.” In truth, it is the most searched type of furnace on the Internet. That should tell you something about its popularity and viability.
Bio-Fuels: The Fuel Of The Future
Biomass burning has an overall impact on the atmospheric chemistry as well as the climate. When there is a fire in the savannas, or tropical forests, or like the recent California fire, large quantities of particulate matter and trace gases are released.
Biomass fuel is also known as Bio-fuel. Bio-fuel is defined as liquid, solid or gaseous fuel that consists of biomass. Biomass fuels can be used for generating power and also for heating purposes.
Biomass fuels can help greatly in reducing the various greenhouse gas emissions and at the same time can increase energy security by being an alternative to fossil fuels. Today, you will find expansion of bio-fuel industries in Asia, Europe, and America.
Bio-fuels are most commonly used in automotive transport like the E10 fuel. They can easily be produced from any source containing carbon like plants. Biomass is mostly derived from living organisms, which includes animals, plants, and their by-products. Manure, crop residues and garden waste are some of the different sources of biomass. This is a renewable energy source that is associated to the carbon cycle as compared to various natural resources like coal, petroleum, and nuclear energy.
Some of the most popular agricultural products that are grown for the purpose of creating Bio-fuel in the United States are soybeans and corn while Europe uses wheat, rapeseed and sugar beet; sugar cane is grown in Brazil, Jatropha in India and palm oil in South-East Asia.
In the early part of 2007, Diversified Energy Corporation with the help of North Carolina State University (NCSU) geared itself for a breakthrough in biofuel technology, which has been named Centia. Centia has been positioned for producing military and commercial jet fuel and can even act as a biodiesel additive in cold or freezing weather. The process of developing Centia looks promising and is expected to deliver a high energy efficiency level that can be in excess of 85%.
There are a wide variety of scientific experiments being conducted, globally, to produce a viable bio-fuel that will be efficient and environmentally friendly. Scientists have started to look beyond the bio-fuels and started to work on the various byproducts of bio-fuel that can be used and even consumed as food in our daily lives.
Considered as an integral part of the green revolution, bio-fuels offer quite a few advantages over other fossil fuels like coal and petroleum. Bio fuels have the ability to recycle carbon dioxide with every growing season by getting it from the air to convert it into biomass. So unlike coal, which upon burning releases carbon, biomass in a way traps all the carbon that is in the air. This is an important aspect from the point of view of global warming because it doesn’t release any carbon components into the air. The biggest advantage over conventional fuel is that bio-fuel is renewable and hence they will not deplete the limited natural resources of our planet.
Common Biomass Fuels
Here is a list of some of the most common first generation Biomass fuels:
Vegetable oil
Vegetable oil is used for cooking food and also as a fuel. Vegetable oil is not high quality oil for fuel use but it is still used in older diesel engines, which are equipped with an indirect injection system.
In most of the cases, vegetable oil is used for manufacturing bio-diesel that is compatible with most of the diesel engines. It is normally blended with conventional diesel fuel for optimum efficiency.
Bio-diesel
Bio-diesel is one of the most common Bio-fuels in Europe. It is produced mainly from fats or oils using the process of trans-esterification. It is a liquid that has a similar composition like that of mineral diesel. The chemical name for bio-diesel is fatty acid methyl ester (FAME).
The oil is mixed with methanol or ethanol and sodium hydroxide, which initiates a chemical reaction to produce glycerol and bio-diesel (FAME). The process produces 1 part of glycerol per 10 parts of bio-diesel.
Bio-diesel is extensively used in diesel engines after it is blended with mineral diesel. Some countries like Germany have manufacturers Volkswagen, who provide a cover on their diesel engines as a part of their warranty for 100% bio-diesel use.
A majority of vehicle manufacturers still limit to use of 15% bio-diesel blended with mineral diesel. In some of the European countries, 5% bio-diesel blend is widely used and even available at gas stations
Bio-ethanol
Ethanol is one of the most common Bio-fuels across the world. It is also known as an alcohol fuel and is produced by fermenting sugars, which are derived from corn, wheat, sugar cane and sugar beet. The various production methods for ethanol are fermentation of the sugars, enzymatic digestion, distillation and drying.
The use of Ethanol has been widely seen in petrol engines where it replaces gasoline. Almost all the petrol engines in the world can run on 15% blends of bio-ethanol with gasoline.
With an eye on the diminishing natural resources, its time for us to usher in the bio-fuel era!
Bio Pyramid
In the ongoing energy debate, biomass energy is getting a lot of play among politicians. To understand the concept, it first helps to understand the bio pyramid.
Bio Pyramid
All of the organisms in the world follow orders of classification. Whether you choose to put them into groups of plants and animals, herbivores and carnivores, or any other of the many different types of classification systems, organisms can be put into many groups in order to understand their relationship to one another. One way to classify organisms is to put them into their order, or hierarchy, in the food chain. In this way, we can see how animals and other organisms relate to each other based on what they consume.
There are several different ways to look at the food chain, and one important and useful tool in this area is the bio pyramid. A bio pyramid is a graphical chart that shows the comparative mass of the consumers to the producers in the food chain. This can be helpful in determining how energy is transferred to the top levels of the pyramid from the bottom levels.
Each level in a bio pyramid is composed of a trophic level. Trophic levels are groupings of different “consumer” groups, such as primary producers (usually just plants or other photosynthetic organisms) rising all the way up to carnivores (such as humans). While a typical biological pyramid might group these consumers in order of energy produced, a bio pyramid shows them in order of total mass from highest to lowest. This often means that the primary consumers, such as the plants, are at the bottom because they are more numerous and take up more mass. The levels are built upon then by how many upper level organisms could survive based on the level below. An example can be seen in this sea bio pyramid:
It would take 1,000,000 kg of phytoplankton (1st level), to feed 100,000 kg of zooplankton (2nd level), to feed 10,000 kg of shrimp (3rd level), to finally feed 1,000 kg of large fish. The final level, the 5th, would only be able to have 100 kg of shark supported by the levels below.
In this way, a bio pyramid shows the inefficiency of the food chain, and lets researchers know that if a level was able to be skipped (such as a shark dipping down and eating shrimp instead of fish), more energy would be conserved and the food chain would lose less energy along the way. Given this fact, a bio pyramid is an important tool when looking at the laws of conservation of energy among different classes of organisms.
Asia, Africa and Climate Modification
As often seems the case, less developed countries seem to receive the bulk of the impact when it comes to negative world developments. The third world and climate modification is no different.
Third World and Climate modification
By definition, climate modification impacts the globe as a whole. That being said, is it possible to predict specific results in certain regions of the world? While there is no definitive answer, the impact on third world countries in Asia and Africa has been the subject of much discussion. Let’s take a look.
Africa is considered a third world continent because a vast majority of the African countries have underdeveloped economies and living standards. Unfortunately, Africa is also believed to be one of the most heavily impacted areas when it comes to climate modification. More than half the people in Africa live in rural areas with agricultural economies. These communities rely heavily on naturally occurring rain resources, to wit, planned irrigation is minimal. This, of course, results in the horrific famines we see on television. Climate modification is predicted to devastate Africa because it is believed the greenhouse effect will reduce the amount of rain received on the continent. As the Sahara Desert expands, less land will be available for farming and the problem will grow worse. Malnutrition from famines will lead to weak immune systems and disease will be prevalent. If the predictions are accurate, Africa could become a living nightmare.
Climate modification could devastate Asia as well. You might be surprised to learn that over 60 percent of the human population lives in greater Asia. This mass of humanity has stretched agricultural and health resources to the maximum. To top it off, large population centers sit right on the coastline in flat areas only a few feet above sea level.
If climate modification trends continue, we will be saying goodbye to large chunks of Asia. Cities such as Jakarta, Tokyo and Bangkok sit at sea level. If the melting polar caps result in a three foot rise in sea levels as predicted, these cities will be underwater. Countries such as Vietnam, Indonesia and Bangladesh are expected to lose 37,000 square miles of coastline under a similar situation. Over 34 million people will suddenly have to move to already congested population centers. Economies, health care and food supplies will undoubtedly reach critical levels.
Is there any good news when discussing the third world and climate modification? Yes. The first step is to put regulations in place that reduce greenhouse gases. Second, proactive planning must be undertaken to account for these potential effects of third world climate modification.

Antarctica, Is It Really In Danger?
With all of the fervor these days about the dangers of global warming many people are concerned about the fate of Antarctica. The fears are that the ice that makes up the continent is melting faster than normal and not freezing back as it usually does with a very even ebb and flow. The concerns are that this will eventually raise the sea level enough to put major cities and land masses under water and leave millions of people homeless and/or even dead.
So who are making these claims? Well there are many scientists that have been looking at the earth’s climates and weather systems for a long time and trying to make sense of them. The earliest reason for doing this was not to measure the affect of the greenhouse gases that are magnifying the suns intensity and causing the heat to stay within it. They originally wanted to learn about the earth so that they could by recognizing signs be could warn of natural disasters like earth quakes and hurricanes and tsunamis. Since they have kept data to look for these signs they have noticed disturbing trends in things like the average temperature and the increasing sea level and other things like the sized of the ice cap over Antarctica and they seem to only be going in one direction which spells trouble.
Then they start looking for why this is happening, and the buzzword is generally global warming. They cite the increase in certain gases like CO2 which are purportedly on the rise do to the millions of different engines that burn fossil fuels across the world. Supposedly this changes the qualities of the atmosphere that hold in the energy from the sun much like a green house does. What people don’t realize is that these are all theories to explain trends in the environment that no one has any clue about. We know that Antarctica melts in places and at certain times and since we have been measuring these things it appears that the land mass has gotten smaller—but this is very flawed thinking.
You see we have only been able to make specialized measurements like this for several decades which may seem like a long enough time to make good guesses about the earth which is thousands of years old (some even say billions). You just can’t make definitive statements about trends that may just be natural cycles that are 500 years in length. Even 100 year or 50 year cycles would not have been fully measured yet. So we must cool our jets and take ourselves so seriously. We know a lot less about the melting Antarctica and many other things that seem to be slowly headed toward disaster than we think.
