Environmental Threats | What you need to know about

Greek philosophers commenced theorizing about the nature as composed of elements like water, earth, ether etc. This nature or environment has always been a jamboree for the inquisitive souls. This is precisely the reason that man has left no stone unturned to explore it. In talking about nature and environment related issues, the foremost question that comes to my mind is that what is environment? Have you ever pondered over the fact that it is not just the foliage and fauna but also the air you breathe, water you drink, things you touch and perceive and even the food you eat that constitutes your environment! You are encased by environment everywhere and anywhere. This environment has friends as well as foes. In case of opponents, the rational selves inject most of these. For instance factories produce and introduce many toxic compounds in the environment that are hazardous for the entire mankind. This article will shed light on some of the significant environmental enemies that envelope us all round the clock.

1.The harmful pollutants like carbon monoxide, lead, sulphur dioxide etc constantly pollute the air around us. Carbon monoxide is a poisonous compound, excess inhaling of which can be unexpectedly detrimental. Studies have revealed that CO enters into our bloodstream and causes breathing disorders and even cardiac arrest.

2.Lead is another fatal element that attacks the nervous system and is largely responsible for causing evils like anemia and high blood pressure. Lead can be threatening to life. So it is better to keep a check on the release of lead in your surroundings. Reducing the consumption can do this and judicious use of lead based products and like paints, batteries and radiators etc.

Other pollutants too that enter the air and water we consume and destroy the sanctity of environment (like depletion of the ozone layer) are very dreadful. They can result in usual minor problems like common cold to major ones like asthma, bronchitis and conjunctivitis etc.

In order to avert the infection due to these pollutants or germs it is better to built up a strong immune system. Although much of immunity is genetically inherited yet it can be significantly improved by intaking nutritious and balanced diet and exercising regularly.

3.When we talk about pollution, noise pollution is also quite disturbing and annoying. A surge in the noise pollution level due to the escalating traffic, industries and factories leads to hazards like insomnia and lack of concentration.

4.The sun that enlightens the whole world can even be damaging at times. The excess of sun’s heat and ultraviolet rays that creep into the earth’s atmosphere due to the exhaustion of protective ozone layer, cause many dermdisorders amongst individuals. To avoid these perils as much possible, wear sunscreen lotion, sunglasses and covered clothes while moving out in the sun.

5.Apart from the pollutants like smoke and other toxic gasses, the pesticides that are sprayed in the fields and on the crops have an injurious outcome. Through the vegetables and fruits we eat these pesticides composed of poisonous chemicals like DDT, Methanol, carbon monoxide etc. enter our body and harm it. Therefore it is advised to wash the fruits and vegetables thoroughly prior to eating or cooking.

Nuclear Radiation Protection


6.The radiations that are released in the atmosphere due to nuclear reactions, nuclear tests, mobile phones, computers and the like are also a source of danger.

7.The enhancement of carbon dioxide in the atmosphere has resulted in global warming which has turned out to be a massive threat to life on earth. Planting more trees and plants that enrich the air with oxygen can prevent global warming.

Safeguarding oneself against the environmental rivals is also a way to cease the damage we do the environment...think about it.

Digital cameras megapixels : Do You Know Your Megapixels?

Until recently, were you to ask someone if they knew how to operate a digital camera, they would react as though you had grown another head. A digital camera? Whoever heard of such a thing. Now, in less than 5 years, they’re the only kind of camera to buy. With digital photography there’s no need for endless rolls of film. You just focus, click, and presto, a digital image. Don’t like the picture you just took? That’s no problem, either. You can simply delete the image.

Now, with all this available technology, why should we ever worry about pictures again? Well, the plain truth of the matter is this, if you don’t have a computer, it’s still expensive and quite time consuming to download your pictures at the local Wal-mart (or Wal-greens), instruct the computer there to copy the pictures to a disk, and then pay for the actual printing. See, it’s at this point that most consumers realize it’s just downright easier to buy an old fashioned, film loaded, camera.

Let’s assume, however, that you do have a computer, and you do want to purchase a digital camera. What kind of camera do you need? Where do you begin to check out your options and see how they relate to your needs? Well, the first part of the process would be to visit an electronics store in your area. The stores that specialize in electronics will generally have a sales person on hand that can explain all the available features of a digital camera and help you decide what you need and what you can live without.

One of the big questions concerns the “megapixel” feature of the camera. The larger the megapixel number, the better the quality of the picture. You see, megapixel determines how the camera reads color combinations in order to produce the best photo possible. Now this might be a matter of great concern if you are a professional photographer, but to the everyday consumer, three or four mega pixel strength is all you need.

Next you’ll want to examine what types of subjects you will photograph and under what kind of conditions. Do you need a camera that makes pictures of moving objects? Are you making your pictures at night, or during daylight hours? Up close and personal, or over on the next block? All of these questions are valid and will affect the quality of the picture you get if not correctly addressed.

There is one final option that you might want to check: some of the digital cameras also do video. The cameras tape the audio and video of the moment as well, or better, than some of your larger video cameras, just not as expensively.

Last but not least, you need to understand your storage options, and determine how much storage space you need. Going to the family reunion, room for maybe 10 pictures will be enough; But now the class reunion, well you’re going to need room for at least 500 photos. Alright, that brings this topic to a close and moves us on to the subject of “memory stix”…….

GPS Tracking 12 Practical Uses for Everyday People

GPS or Global Positioning Systems is a term that most commonly conjures up images of vehicle navigation systems, space-age satellite technology, and interactive maps for outdoors-types and sportsmen. But the reality is that there are far more applications of Global Positioning Systems beyond GPS vehicle tracking or map navigation that everyday people like us can benefit from. All it takes is a bit of creativity, and some trial and error. Here are a few of the many possibilities that can benefit you right now in your busy and hectic life.

1. Know where your children are using services from companies like uLocate Communications.

2. Keep track of elderly members of your family, so that they don’t wander off alone.

3. Plan a road trip around interesting points of interests, landmarks, campsites, diners, etc, and hear fewer "Are we there yets?"- and of course get the most out of that expensive gas.

4. Get emergency road side assistance at a touch of a button from your vehicle, so you can get help exactly where and when you need it.

5. Keep a visual journal and bookmark collection of your favorite hot spots, sceneries, and points of interests, that may not be listed in any travel guide (You can create your own mini travel guides and memories).

6. Find lost pets easily using collars with built-in GPS, better than running around in your pajamas hollering like a maniac.

7. Feel safer with cellular phone 911 calls, so emergency personnel can pinpoint your location once you make an emergency call. Please double check your carrier service to see that it has GPS features and get a primer on how it works if possible.

8. Get to your interview, or any important time sensitive destination or engagement, faster by finding shortcuts and correct directions.

9. Find a good Italian restaurant near your movie theatre on the fly.

10. Track your luggage, laptops, and anything of importance while traveling.

11. Track and find family, friends in a crowded concert, graduation, or any social gathering.

12. When going on a vacation, feel free to separate from group for a while to venture on your own based on your own interests and find them later on with your GPS enabled device- even in an unfamiliar place.

Our ability to use GPS so far is limited by the relatively poor connection to the satellite feeds when we are indoors in buildings, homes, or behind anything that could obstruct the GPS connection. However with the investment and development in a new satellite network called Galileo which should be completed in the near future, these problems should be eliminated drastically. Despite these problems, GPS still offers a world of benefits as mentioned earlier, and with any technology, it will only get better.

In addition to more practical usage applications, GPS will make a great educational and fun gift for your loved one’s and friends as well. Consider just two of the many creative and educational uses of GPS:

1. Stay physically active and fit by playing RayGun! A locational based cell phone game based on GPS technology.

2. Become more cultured, make global friends, and learn about the world playing GeoCache, a global GPS based treasure hunt.

With many affordable feature-rich models to satisfy anyone’s preferences and budgets, now is as good a time as any to learn more about GPS technologies, which are surely to become more assimilated into the mainstream within the decade. One day we will take these things for granted just like we do now for the internet and cell phones. The key is to dive in, without paralyzing yourself with the overwhelming array of choices in the GPS market, and enjoying some truly amazing technology.
