Save our earth, life would be better
We live on the beautiful and picturesque earth. Do we have the awareness to keep our home? The Earth is our home. Earth is where we stand. The Earth is our breath. We have a great responsibility to protect our planet from destruction. We often pay attention to how the earth has always been a natural resource for us. Whatever we need, we get from nature. Especially when talking about the staple food, the earth is our primary source. It is naturally, if we celebrate Earth Day 2010 with a variety of ways. There are many ways that we can do to preserve the style of the mini to keep it beautiful and so beautiful because we need the earth as our home. You should never ignore the preservation of the universe as the place we live and do various activities.
However, today many people are almost forgotten in the conservation of nature. This indicates that the earth was in a dangerous condition caused by human apathy toward nature. We can notice the little things around us where people are no longer friends with nature. Air pollution resulting in the earth’s air is polluted, and we breathe it every time, what happens next is that many living beings who suffer from respiratory problems. Factories that dispose of waste at random, for example to the flow of the river, which water is always a need for human life, but due to polluted river water waste, human beings will be affected by skin diseases or toxic to drink. Effect of greenhouse gases that cause depletion of the ozone layer, humans finally feel the immense heat and this is what we commonly refer to as global warming.
We have many opportunities to improve this bad situation with a variety of activities that can save the earth from destruction. For example by planting trees as acts of greening. Or provide information to the public in order to utilize the vehicle as needed only. In addition to our generation was taught to throw garbage in the appropriate fields.
Air Purifiers and Filters Guide
Have you ever wondered what is floating through the air in your home? Just because you can’t see something doesn’t mea n it isn’t there. Millions of particles, pollutants, gases, bacteria, and allergens are roaming your house with no way to get out making the air inside your home up to 100 times dirtier than outside air. Sure, opening a window to let in fresh air may get that stale smell out, but it is only an open door to invite more particles inside your home.
This contaminated air circulates through your home and either settles on flat surfaces in the form of dust or is breathed in by you and your family.
Fortunately, your house does not have to fall victim to these airborne pests. Air purifiers are more common and affordable today than ever before. If you do not have an air purifier, knowing the different types of air filtration devices will help you before you buy your own.
1. HEPA filters: Short for “High Efficiency Particulate Air filters”, these devices use a cloth-like filter which can trap more than 99.97% of particles in your house. The filter lasts a couple of years depending on the condition of the air and can actually trap more pollutants than other filters. The downside is the HEPA filter is noisier than its competitors and does not eliminate gases or odors
2. Ionic Filters: Ionic filters purify the air by sending our ions which oppositely charge the particles so they stick together and collect on magnetic plates inside the filter (much like how your hair sticks to a balloon after it has been rubbed on your head). These devices are often a favorite among customers because of how silent they are. They are even effective enough to clean viruses, gases, allergens and bacteria out of your household air.
3. Carbon air filters: These devices are, by far, the most effective odor removers on the market. They work though a system of highly absorbent pores which trap molecules by forming a strong chemical bond. They don’t, however, trap any airborne allergens or germs.
4. Ultra-Violet Light filter: Ultra violet light haven been proven to sterilize micro-organisms if they are exposed to the right amount of light for a certain length of time. Alone, there is some doubt to the effectiveness of these filters because micro-organisms may not be exposed to the light long enough while they are passing though the air. In order for ultra violet work to be successful, HEPA is used to capture the air long enough to be sterilized by the light. While ultra violet kills microorganisms, HEPA can rid your house of allergens.
5. Hydroxyl Radical filter: Hydroxyl radicals occur naturally in the earth’s atmosphere and are powerful cleansing agents. They are, in fact the most powerful method of sanitizing mold and other harmful bacteria.
These five types of filters are the most popular and dependable on the market. Now that you have a firm understanding of how these filters work and what exactly they clean out of household air, do your homework. There are many great filter providers online which can lead you to the best filter for your budget.
Air Purifiers – A breath of fresh air
Air purifiers are devices employed in homes and business all over the world. Due to the amount of dust etc indoors, air purifiers are used to clean and ‘purify’ the air inside the building, circulating it until it is free from unnecessary particles.
An air purifier usually takes the form of a mechanical wall unit, but can be stood on the floor and vary in size, some squat box shapes and some slender towers. Prices vary in a wide range but there are many websites devoted to their sale, as well as a large variety of manufacturer. They use a variety of methods to remove contaminants from the air. Some use electricity to suck particles out of the air, while some use absorbent materials. All air purifiers must be cleaned regularly to keep them working properly, as most manufacturers boast at least 95% filtration of known impure air particles.
The industry benchmark is called the HEPA standard, a system that filtrates 99.97% of particles with a size of 0.3 micrometers (Department of Energy). The original HEPA filter was used in the Manhattan Project to stop airborne radioactive particles. Certain purifiers use UV light that is fatal to some germs. Some purifier manufacturers have come into controversy over units that generate ions in order to react with the contaminants in the air, as some machines produce the harmful pollutant Ozone.
Airborne particles such as dust, pollen and spores build up inside rooms. Many people use air purifiers to reduce the quantity and density of these specks of matter in order to provide a safer, less cloying atmosphere. This is very much the case for sufferers of asthma and allergy sufferers, to whom these particles can be dangerous allergens or hazards. Other uses are to prevent more direct threats, such as gases and even second hand smoke.
10 reasons to buy a hybrid car
Care for the environment? Want to save the planet? Then you must think in terms of fuel efficiency, non-polluting, and eco-friendly transport. The answer lies in purchasing and using a hybrid car. They not just make a statement that I care but are compact and fuel efficient.
Here are some insights that may just tempt you to buy a hybrid.
1. Made of lightweight materials hybrids are small in size. The engine is designed to be fuel efficient. When the car halts at a signal, the engine will automatically shut down and restart when the car shifts into gear.
2. These cars have the advantage of being powered by a gasoline engine and an electric motor that takes care of acceleration.
3. The batteries of the electric motor recharge automatically by harnessing the kinetic energy produced during braking.
4. Hybrid car engines produce less emission, give better mileage, idle less, and are fuel efficient.
5. The aerodynamic design reduces drag and the tires are made of a special rubber that reduces friction.
6. The battery has high capacity and is made of nickel-metal-hydride. The battery can run the hybrid when called for.
7. The power-train technology enables using two power sources and enhances fuel efficacy.
8. There are many choices. You can have a hybrid from Honda, Ford, Toyota, GMC, and Chevrolet.
9. If your transportation of choice is a hybrid then the US Government will applaud your choice by giving you significant tax breaks.
10. Using a hybrid means you are active in ensuring the air is clean and that you are a concerned citizen who wishes to save fuel which is precious.
Maximize usage by “pulse and glide.” This means finding the ideal point where electric and gas energy are equally utilized. Generally this ideal lies between 30-40 miles per hour. Stabilization of energy is learnt by practice it really cannot be taught. Another important aspect is that you benefit if you don’t rush around and drive at the prescribed speed limit. If you glide, instead of accelerate then you can make a saving of as much as 10 cents a gallon. Lastly check and maintain tire pressures. This will help lengthen the life of the tires and help you save fuel. Reduced tire pressure studies indicate reduces gas mileage by as much as 10%.
Before you say “yes” to buying a hybrid car, you must do in depth research on hybrids, the pros and cons. Talk to manufacturers and owners. Test drive the different makes and check which one would suit your life-style. Some hybrids are ideal for city driving while others are more efficient on open roads.
Even if the buying price is steep the fuel that you save along with incentives like tax breaks make a hybrid a good and sensible choice.
“Don’t Touch It,” and other simple, nature-friendly advice
Each summer, I visit the Chequamagon National Forest in Wisconsin. An amazingly beautiful and lush forest, this place is my sanctuary. I stay at a low-key resort, in a cabin overlooking Lake Namekagon. It’s a breath of fresh air – quite literally – to spend two weeks each year at this place, away from bustling streets and busy people. It’s like a different world.
Or, at least, it was. I had a very different experience this past July. Upon entering our cabin, my fiance and I were greeted by a large television, equipped with Direct TV. Don’t get me wrong: I’m a TV-lover, through and through. There was, however, something strange about having to look around the television to see the lake.
We overlooked this; after all, we don’t own the cabin. Some resort-goers might crave 500 channels before they crave hiking and fishing. Convinced that the TV (both the sight of it and the temptation to watch it) would put a damper on things, we went out on the water.
As I started the old, rented pontoon boat, something occured to me. We were no better than the TLC, MTV, and MSNBC addicts. Yes, our boat was used for the enjoyment of the outdoors; however, it left a muddy, green wake behind it. Yes, we came to the resort to get away from everyday conveniences and to surround ourselves with nature, but we were staying in a cabin – not a tent or a sleeping bag. We cooked our breakfast every morning on a fairly modern stove, we drank coffee made in a Bunn coffeemaker, and we turned on the electric heat if the cabin got too cold. It turns out we weren’t roughing it; we were faking it.
Since this realization, I’ve been troubled. I don’t understand where our appreciation for nature went. I don’t understand how misguided travelers – myself included – consider themselves to be experiencing nature, when really all we’re doing is glancing at it between commercials. Granted, everyone experiences nature in a different way. For some, glancing at it through a window – or on a TV screen – might be enough.
I’m concerned, though, that by accepting this as a legitimate way to experience nature, we are missing something. Or, perhaps, we are missing everything. On a basic level, there is something satisfying about feeling a different kind of air on your skin, and about feeling the crunch of leaves and dirt beneath your feet. Where city lights don’t corrupt the night sky, we can see stars in a new way, and the level of darkness is foreign and exciting.
There more to this simple human/nature combination than deep satisfaction, though. There is a danger present in the ways we currently explore nature. It is common for travelers to hop on boats, jetskis, waverunners, or ATVs to travel through lakes and forests. In these cases, vacationgoers are experiencing nature – while leaving a trail of pollution behind.
And what about our cabin? Built in the middle of the forest, trees had to be removed in order for the resort to exist. There is an inherent disconnect, here: the resort was designed to house nature-loving travelers who want to see the forest’s natural beauty, and yet in order for the resort to exist, some of the forest had to be cut down. Instead of experiencing untouched and unscathed nature, vacationers are experiencing a forest marred by human interference.
This is the way with us. We, whether intentionally or accidentally, can’t help but tinker with nature in its natural forms. Even when we attempt to truly experience it, we are also hindering it. So, we must consider some simple pieces of advice if we wish….(read the full article at the link below)

Hybrid Electric Car: A Promising Technology for a Promising Future for the Environment
A hybrid-electric vehicle, or HEV, combines an electrical energy storage system with an occupied means of generating electrical energy, usually through the consumption of some type of fuel. Each type of HEV has its own operating quality and chosen design practices, as well as advantages and disadvantages.
The development of interior ignition engine vehicles, especially in automobiles, is one of the supreme achievements of modern technology as a new rising energy saving and environment -friendly vehicle, that’s why the hybrid-electric vehicles were created to give convenience to every human.
In the process of creating the hybrid electric car, the most important is the energy saving and the environmental protection. Wherein nowadays this are the common problems faced by the society.
Having the hybrid-electric car evolved from the electric car. However, the main disadvantage of the electric car is that it is mainly dependent on the batteries. Therefore, has limited range.
First of all, the hybrid electric car was supposed to be an electric vehicle with batteries for power storage and is also equipped with an on-board heat engine-powered generator. This means that this type of hybrid has an extended range.
The heat engine power and the battery power are specifically intended as an important scheme that constantly modulates the excess between the heat engine and the battery power systems. This will also depend on the driving schedule.
Since the beginning of the use of automobiles, electric cars have been already recognized and conceptualized. Even though the electric power train is better in various aspects, as an energy source, the battery was unequal to the superior-energy content, easiness in terms of the handling, and inexpensive and profuse supplies of motor fuel.
Now, it has almost been a century since the electric car has been popularly discussed, but recent developments in the HEV technology and the growing concerns for the environment has revived the drive for an HEV and this has become a realization today.
We can consider the personal means of transportation as a very important bond in the economic chain of today’s modern societies and that a private vehicle appears to be the popular choice.
Electric vehicles are more energy efficient than the contemporary vehicles wherein the electric vehicles operates at approximately 46 percent of effectiveness, while a contemporary vehicle operates at about 18 percent only.
There are studies that generally concludes that electric cars with batteries are approximately 10 to 30 percent more efficient with energy than the usual gasoline cars, depending on the exact assumptions of the vehicles energy usage and energy chain efficiency.
Certainly, the comparisons of the electric vehicles and the conventional vehicles are comparisons between an extremely developed power system that is nearly in the end of its research and development, and the innovative power system in the beginning stages of the development wherein important development can be expected as the new technology evolves.
Furthermore, the advantages of electric powered modes of transportation extends beyond the true outlook of economizing energy. Electric generation plants can use substitute fuels that are not adaptable to portable power systems.
Electric vehicles are the definitive alternative fuel vehicles because their power is taken from the source fuels utilized to produce electricity. Aside from that, the flexibility of the fuel alone can offer important useful and economic advantages especially in relation to a variety of energy resources.
The electric car is truly a promising technology that could transform one’s means of transportation into a far more environmentally type of commodity. Through this innovation emission controls become more important, effective and economically beneficial.
