Helping Kids Care: Ideas For Earth Day and Beyond
Earth Day is April 22, and while it’s important to get involved on this day, there are things we can do as families that will make a huge impact throughout the year.
It starts with helping our kids to celebrate the world in which we live, and it continues with helping them to love it so much that they want to do everything they can to help protect it. Here are six ideas to help your kids celebrate and care for our earth:
1. Get out and enjoy it. Researchers are now saying that simply getting kids outside in nature may be the most effective way to raise their awareness of environmental issues. Suddenly, these problems that they hear about on the news and in the classroom have a real impact on their daily lives. They see firsthand how a forest or a beach or a tidepool or a meadow is teeming with life, with ecological relationships that are interdependent, delicate and complex.
To encourage your kids to get out there and enjoy the natural world, you may have to purposefully inject some extra excitement in the idea, but just at first. Take your dog (or a friend’s dog) for a walk in the woods. A dog’s love for nature, and subsequent enjoyment of it, is infectious. Create a list of things to find and make your adventure into the outdoors into a scavenger hunt.
If possible, and if your kids are old enough to be by themselves out there, find a safe place for them to play in a natural environment. Allow them to go there to get away, to sit and think or to talk with their friends. Make a point to get the kids out in nature every day. Better yet, go with them.
2. Watch “An Inconvenient Truth” as a family for inspiration. Invite some of your children’s friends over to watch it with their parents and talk about some initiatives that you can each commit to or some larger projects that you can work on as a neighborhood or community.
3. Help your kids learn about endangered animals. Together, look into organizations that help endangered animals and see how you can get involved.
4. Reduce and re-use, then recycle. Lots of kids get excited about recycling. Fewer are into reducing or re-using. Model to your children a healthy pattern of consumption. Talk frequently about the many benefits (which go way beyond environmental) of living a simple life and of being wary of a lifestyle of mass consumerism. As kids spend more time outside and less time at the mall or watching television advertisements, this shift may feel increasingly more natural to them.
5. Teach your kids about potentially harmful chemicals and how they can be everywhere in our world: in the foods we eat, in the supplies we use to clean the house, in our paint, in our cosmetics, in our lawn care products. Turn the search for these things into a game and allow your kids to be detectives, learning about and seeking out these harmful chemicals and then finding natural alternatives.
6. The next time you take the kids to the grocery store, see how you can minimize the amount of packaging that you purchase. We have been known to purposefully not purchase an item because of the manufacturer’s use of wasteful packaging. It won’t take long for the kids to realize that the best item in the store for minimal packaging: raw fruits and vegetables.
In our family, the more we can make these life changes into a game, the more apt the kids are to follow suit. Help your kids to understand how one person really can make a difference (especially when that person is part of a committed family or group) and review often the personal impact that you all have made.

A Change in Krill Ecosystem
by Green Earth Fan on May.28, 2009, under Proven Green Technology and Methods
A Change in Krill Ecosystem
Antarctic Peninsula has been experiencing warming trends for over 40 years with an increase of 2-3 C, thus correlating with lower sea ice conditions in the Amundsen Sea and Bellinghausen Sea. Warming temperatures around the Antarctic Peninsula is changing the dynamics of the ecosystem. The rise in atmospheric temperature is causing increasing in melting of freshwater glaciers and ice shelves. Fresh water emerging into the sea counteracts the salinity within a regional area. Changes identified are;
• Decrease in sea water salinity up to 60 miles offshore
• Lower sea ice
• Decreased krill population
• Increased salp (open ocean tunicate that is reminiscent of a jelly-fish) population
• Increase in cryptophytes (single cell phytoplankton algae)
• Decrease in diatom phytoplankton
• Increase in carbon sequestering in deep ocean sinks
• Decrease in carbon availability in the food chain
The Antarctic Krill (Euphausia superba), a small shrimp like crustacean is the most important zooplankton species associated with the sea ice and plays a crucial role in the Antarctic food web. On a regional basis the amount of krill appear to be declining in the southern ocean. There are definitely lower trends in krill population during lower sea ice years around Antarctica. Part of the rational for the population decline is that ice algae rely on the sea ice for protection and growth. The krill need the sea ice in order to feed on the algae and phytoplankton.
Krill occur in groups or large swarms. They are less than 3 inches in size and feed primarily on phytoplankton and sea ice algae. Krill filter diatom phytoplankton out of the water column and scrape algae from the sea ice. Apart from frequenting the sea ice to feed, krill in particular juveniles, seek protection from predators in the many nooks and crannies formed by the deformed sea ice floes. Krill is the staple food of many fish, birds and mammals in the Southern Ocean. The biomass of Antarctic krill is considered to be larger than that of the earth’s human population.
Sea- ice algae utilizes atmospheric carbon dioxide for its energy source, the same as plants do on land. Krill diet of the sea-ice algae and phytoplankton is essential for converting the carbon for use in higher animals such as fish, birds, and whales. This carbon conversion is a very critical role in predatory nutrition. Additionally krill do eliminate some of the silica from the diatom shells and carbon in sticky balls that sinks nearly two miles into the deep ocean. These cold, deep waters are able to contain carbon dioxide and prevent the gas from rising to the surface, thus immobilizing carbon that is not passed into the food chain.
In recent years there have been increases in algae phytoplankton called cryptophytes. Mark Moline, California Polytechnic State University, states that the cryptophyte population correlates with warmer temperatures and lower salinity waters that are produced by the melting of the freshwater glacier. Cryptophytes measure around 2 mm, while other plankton in the Antarctic waters are much larger and measure 15 to 270 mm. Along with the increase in cryptophyte population an increase in salp, a pelagic tunicate, population has also occurred. There are differences between salps and krill. Salps feeding efficiency is capable of grazing on smaller food sources less than 4mm, whereas, the Antarctic Krill efficiency declines on any food less than 20 mm. The salps compete with krill for the phytoplankton and thus decrease the krill population. Additionally the salps feed on krill larvae, which also cause a decline in krill numbers.
The warming trend in the Antarctic Peninsula is showing a pattern of increasing cryptophytes over other phytoplankton and the increase in the salp. This influence is due to the low sea ice and the lowering of the salinity in the seawater. Salps and cryptophytes do better in the lower salinity, while the krill and other plankton are unable to tolerate the increased freshwater regime from the glacier ice melts. This selectivity gives preference to the salps as the dominant species while decreasing krill abundance. During lower sea ice seasons the density of krill declines while the salp population increases.
Carbon sequestering into the deep ocean from the algae and phytoplankton occur by both the salp and krill. Both species eliminate the atmospheric carbon received from the primary producing algae by producing fecal pellets by the salps and sticky balls by the krill, thereby, reducing the amount of carbon dioxide in the atmosphere. The salps though sequester more carbon into the cold deep ocean than the krill. However, the krill provides the most efficient pathway for carbon transfer up into the food chain. The cryptophyte dominated waters are less efficient in the food chain due to increased feeding by salps and the difficulty of the krill to utilize the cryptophytes as a food source. Migration patterns by penguins are changing, in part due to the changing krill population. Krill is a mainstay diet for penguins, and if the krill population changes, many other ecological changes occur with it.

Are Tsunami’s Caused by Global Warming ?

Are Tsunami’s Caused by Global Warming ?
Throughout the history of our planet it has endured a constantly changing climate. It endured an ice age and has also experienced long periods of heat. But over the last two hundred years, give or take, the temperature of our planet has been steadily increasing. This change in the climate on earth is known as global warming, and global warming is the direct result of the industrial revolution.
Because of the industrial revolution, people are constantly burning fossil fuels such as oil and coal. But by burning these fuels dangerous greenhouse gases like carbon dioxide (CO2) are then released into the earth’s atmosphere. These gases block heat rising from the earth from being able to escape into space. The same basic function that glass panels on greenhouses have, hence the name. Our burning of fossil fuels causes more than three quarters of all carbon dioxide emissions. Power plants and other stationary sources contribute more than half of that amount.
Along with increasing CO2 emissions, deforestation is on the increase as well. This is disastrous, because trees recycle CO2 and release oxygen back into the atmosphere. Because of the rise in deforestation levels the fossil fuels we burn are seriously jeopardizing our planet. We know that global warming is the cause of glaciers getting smaller and for the rise in sea levels. Plants and animals show clear and undeniable signs that they are affected in many different ways. Earth is experiencing longer seasons which results in rivers and lakes freezing later than usual and melting sooner. Without a doubt, global warming causes many changes and affects our planet in many ways but can it also cause a tsunami?
Nobody will ever forget the utter destruction, grief and loss left behind after the huge tsunami that hit parts of Asia on December 26th, 2004. Hundreds of thousands of people were killed, injured and traumatized. The areas it hit were left completely destroyed.
Generally speaking a tsunami is made up of a series of waves. More often than not the first one is the mildest. Prior to the arrival of the first wave, the shoreline recedes dramatically and often leaves the ocean floor exposed. They mostly occur where the water is shallow but they can also occur around coastal areas. In deep water a tsunami appears as a big wave and nothing more. In shallow water this is not the case. The wave can reach as high as one hundred metres, although, in all honesty, this is not at all common.
We know that tsunami’s can be caused by an earthquake, but this is not the only cause. They can also be caused through volcanic eruptions and landslides. Another cause is if a large amount of water is somehow displaced, such as when meteors happen to fall into large bodies of water. Tsunami’s are caused by events that can be, and are, affected by global warming, however global warming itself does not directly trigger the formation of a tsunami. Basically, it is an indirect cause.
One thing is certain, global warming is not a myth as some suggest. The planet is displaying clear signs that we dare not ignore.

CO2 Footprint of a Product
by Green Earth Fan on May.23, 2009, under Proven Green Technology and Methods
CO2 Footprint of a Product
We’ve certainly seen quite a few companies come out and say that their manufacturing facilities have a zero impact on the environment, meaning zero footprint, but indeed, there is much controversy on how to determine what a zero foot print is. It’s almost impossible to get to zero, even if a company goes and plants 10,000 trees over the course of 5-years.
The other day at a Think Tank meeting, we were talking about how to establish a complete CO2 discharge chain of a product, including all its components in the process of making it. From the wrappers, card board box, printing, assembly, energy to do all that, the distance the people traveled to work in what type of cars, etc. I mean really narrowing down the actual discharges.
Not because we are Global Warming alarmists, but because we feel it is not exactly correct for a company to claim Zero Emissions. And that we must have a more realistic view of the total process, Supply chain and all.
Many companies like Dell in Texas have stated that they have finally achieved zero emissions, but they were attacked for stating that, why? Because, everyone has a different concept of what nothing is. In other words we are all out there fighting over nothing and that makes no sense to anyone, no matter how you figure it.
Indeed, we should be applauding Dell for their solar panels, LEEDs certified warehouses and assembly plant and all their hard work and meaningful dedication to do the right thing. And yet, we are not doing that are we? Instead we find people attacking businesses, even those that go out of their way, spending millions of dollars to do the right thing. I ask are we doing the right thing by allowing persnickety environmental complainers to attack America’s greatest companies?

Goes to the Animals: Vibration and Noise Control
by Green Earth Fan on May.22, 2009, under Proven Green Technology and Methods
Goes to the Animals: Vibration and Noise Control
Noise and vibration control is an issue that is much more common than one might originally think. In fact, it can creep up in the most unlikely of places. A good case in point is animal lab environments. Indeed, ALN Magazine recently ran an article titled “Noise & Vibration Considerations for the Animal Lab Environment.” Therein, the publication pointed out, “In the lab animal facility setting, noise, sound, and vibration affect the life cycle, interaction, and behavior of animals.” However, because “the impact of noise, sound, and vibration is a largely undocumented factor in the research,” it’s an often overlooked issue.
“If the sound pressure levels get too high,” the article continues, “there is a negative impact on animals and structures.” Vibration control, however, is just as important to these animals as noise control in that it “is a driving force behind radiated sound.”
Obviously, exposure to noise and vibration can be detrimental to an animal’s hearing, but the risks don’t stop there. “Sound and vibration can [also] have a physical impact on animals.” Even more startling, “Smaller animals are more susceptible to the affects of sound and vibration over time and will adapt or adjust accordingly. In some cases, mutations may result from exposure to undesirable conditions.”
How can animal laboratories mitigate these problems? The magazine notes, “The designers can control items that are constant disturbances that may greatly impact the animal community. Items within the designer’s control include ventilation system design, machinery vibration isolation, wall construction, lighting selection, and computer terminal placement.”
During the design process, animal labs may want to consult with a producer of custom-molded rubber and rubber-to-metal bonded parts for noise and vibration control. A world leader in the creation of rubber molding and rubber-to-metal bonded parts can help to create an environment that is not only safe for the animals being kept there but is also conducive to a healthy work environment for the people who are employed there.
The Vibro-Insulator line of isolators and mounts, in particular, aid in the control of noise, vibration, and shock. Selecting the right type of mount for an individual animal lab’s specific applications can prove tricky, however. That’s why consultation with an expert with reputable qualifications in rubber molding and rubber-to-metal bonding can be very beneficial.
Of course, once professional advice has been obtained, browsing the Vibro-Insulator catalog allows animal labs easy navigation so they can select the correct mount for their application. Rubber Vibro-Insulators come in a variety of styles and sizes to handle most vibration isolation problems. Most of the mount styles are designed to be used in either the compression or shear direction.
Selection of the proper Vibro-Insulator for a specific application boils down to a multi-step mathematical function that an expert can calculate for the lab or into which the lab’s design team can plug the following information:
1. The maximum load that must be supported.
2. The number of mounts supporting the load.
3. The frequency of the disturbing vibration.
4. Any restrictions on the size or style of the mount based on space limitations or assembly considerations.
