Great Barrier Reef Disappearing

Posted by Troy on September 8, 2009

Once carbon dioxide had hit the levels predicted for between 2030 and 2060, all coral reefs were doomed to extinction, Charlie Veron, former chief scientist of the Australian Institute of Marine Science said commenting the situation with The Great Barrier Reef disappearing, “it will be over within 20 years or so”, he predicts. “They would be the world’s first global ecosystem to collapse. I have the backing of every coral reef scientist, every research organization. I’ve spoken to them all. This is critical. This is reality.”

Is there no way out, no loopholes? The Royal Society and the International Program on the State of the Ocean (IPSO) held a crucial meeting on the future of coral reefs in London yesterday. In a joint statement they warned that by mid-century extinctions of coral reefs around the world would be inevitable. The international conservation group WWF warns that 40% of reefs in the Coral Triangle have already been lost. The area is shared between Indonesia and five other South East Asian nations and is thought to contain 75% of the world’s coral species. There are ways to avoid the worst-case scenario and one of them is significant reductions in greenhouse gas emissions and better controls on fishing and coastal areas.

Green Festivals

Posted by Troy on August 12, 2009

Recently Green Festivals has grown and widen around the world and that’s no wonder. And what is more different festivals are moving towards a greener now. You must admit that the cause of such tendency is more than evident and such events as San Francisco Green Festival call to remind us that our world has finite resources and we should try all our best to go green to change the environmental situation.

Actually the eco facts are shocking. Don’t you know that according to latest statistics the amount of wood and paper we throw away each year is enough to heat 50 million homes for 20 years and 99.5 percent of all fresh water on Earth is in icecaps and glaciers. Each gallon of gas used by a car contributes about 19 pounds of CO2 into the atmosphere. For a single car driving 1,000 miles a month, that adds up to 120 tons of CO2 a year. About 110 million Americans live in areas with levels of air pollutants the federal government considers to be harmful and so on.

So, no doubt that planning to take part in a green festival is a good idea to learn to become not so aggressive in respect of Mother Nature, to learn that money is not all you have to save, that one has not wait until the last tree has been cut down…the last river has been poisoned…the last fish caught, to find that money cannot be eaten. Green is the color of hope, of ecological balance, of our and our children future at last. This year the Green Festival will come to San Francisco on November 13th through 15th, Friday and Sunday so you have great opportunity to find San Francisco Vacation Rentals deals and discounts right now online. “We all speak a lot about the loss of the quality of life through the destruction of our ecology”, said Ed Asner, “and yet every one of us, in our own little, comfortable ways, contributes daily to that destruction. It’s time now to awaken in each one of us the respect and attention our beloved Mother deserves”.

Is There Asbestos in My Home?

Posted by Troy on July 22, 2009

The short answer to the question, “Is there asbestos in my home?” is “Yes, probably.” How much, where, and whether you should worry, depends mostly on when your home was built and what condition it is in.

In the U.S., if your home was built after the mid-1990s there might be asbestos in roof shingles, floor tiles, cement pipes and boards, caulking compounds, and joint cements. However, this is not necessarily something to worry about.

Asbestos is a mineral that breaks into small fibers. The fibers are dangerous to breathe, because if they settle in the lungs they can cause mesothelioma, a deadly lung cancer, and asbestosis, a debilitating disease that interferes with breathing. You should also avoid ingesting asbestos. However, as long as the asbestos fibers are encased in something so that the fibers can’t be breathed, or get into your water — generally the case with newer construction materials — you can safely leave it where it is.

Insulation in Home Built Before the mid-1990s

Homes built between 1920 and 1950 may have asbestos insulation. Also, be aware that homes built after 1950, and possibly as recently as the mid-1990s, may contain an insulation called Zonolite made of vermiculite contaminated with asbestos. The vermiculite came from a mine in Libby, Montana, a community so contaminated with asbestos the EPA recently declared Libby to be a public health disaster.

As long as the insulation is enclosed in a wall where fibers cannot escape, it is not hazardous. However, if walls are damaged, or if your remodeling plans involve cutting into a wall, you must arrange for state-certified asbestos abatement specialists to deal with the insulation. They may either remove it or find some way to contain it. But do not handle the insulation yourself.

Asbestos in Homes Built Before 1980

Here are just some of the other places you might find asbestos in an older home:

Shingles and walls. From the 1920s and until 1978 asbestos cement shingles were a popular choice for housing exteriors. Also until the 1970s, cement sheet, millboard, and paper with a high asbestos content were used around fireplaces and wood burning stoves. Cutting or drilling these materials can release asbestos fibers into the air you breathe.

Soundproofing. Until the 1970s, soundproofing material containing asbestos was sprayed on walls and ceilings. Asbestos also was used in textured paint and patching compounds until 1977. The asbestos in these applications can become loose and release asbestos into the air, if they haven’t already.

Hot water and steam pipes. These may be coated with asbestos or wrapped with asbestos tape.

Oil and coal furnaces and door gaskets. Replacing an old basement furnace in your home can create an asbestos hazard.

Inspection and Abatement

At this point, you may be worried about the cracks, chips, and flaking in your older home. It cannot be stressed enough that if asbestos really is present, you need professional help to deal with it. Deal only with asbestos inspectors and asbestos abatement contractors that are licensed by your state.

The first step is assessing whether there really is an asbestos danger in your home. The Environmental Protection Agency recommends that you hire an inspector who is independent from any abatement contractor you might use to avoid a conflict of interest.

Even if there is asbestos in your home, that doesn’t necessarily mean you have to have it all removed immediately. If the asbestos is in a place where it won’t get into the air or water, it may be left alone. But be aware that renovations or damage to your home might release the asbestos, and then you must call in an asbestos abatement contractor. Don’t try to deal with it yourself.

One Sixth of Humanity Undernourished

Posted by Troy on July 12, 2009

Food and Agriculture Organisation of United Nations repoerts that 1.02 billion people hungry 19-06-2009. One sixth of humanity undernourished – more than ever before.
One sixth of humanity undernourished – more than ever before.

The faces behind the numbers.
19 June 2009, Rome – World hunger is projected to reach a historic high in 2009 with 1 020 million people going hungry every day, according to new estimates published by FAO today.

The most recent increase in hunger is not the consequence of poor global harvests but is caused by the world economic crisis that has resulted in lower incomes and increased unemployment. This has reduced access to food by the poor, the UN agency said.

“A dangerous mix of the global economic slowdown combined with stubbornly high food prices in many countries has pushed some 100 million more people than last year into chronic hunger and poverty,” said FAO Director-General Jacques Diouf. “The silent hunger crisis — affecting one sixth of all of humanity — poses a serious risk for world peace and security. We urgently need to forge a broad consensus on the total and rapid eradication of hunger in the world and to take the necessary actions.”

“The present situation of world food insecurity cannot leave us indifferent,” he added.

Poor countries, Diouf stressed, “must be given the development, economic and policy tools required to boost their agricultural production and productivity. Investment in agriculture must be increased because for the majority of poor countries a healthy agricultural sector is essential to overcome poverty and hunger and is a pre-requisite for overall economic growth.”

“Many of the world’s poor and hungry are smallholder farmers in developing countries. Yet they have the potential not only to meet their own needs but to boost food security and catalyse broader economic growth. To unleash this potential and reduce the number of hungry people in the world, governments, supported by the international community, need to protect core investments in agriculture so that smallholder farmers have access not only to seeds and fertilisers but to tailored technologies, infrastructure, rural finance, and markets,” said Kanayo F. Nwanze, President of the International Fund for Agricultural Development (IFAD).

“For most developing countries there is little doubt that investing in smallholder agriculture is the most sustainable safety net, particularly during a time of global economic crisis,” Nwanze added.

“The rapid march of urgent hunger continues to unleash an enormous humanitarian crisis. The world must pull together to ensure emergency needs are met as long term solutions are advanced,” said Josette Sheeran, Executive Director of the UN World Food Programme.

Hunger on the rise

Whereas good progress was made in reducing chronic hunger in the 1980s and the first half of the 1990s, hunger has been slowly but steadily on the rise for the past decade, FAO said. The number of hungry people increased between 1995-97 and 2004-06 in all regions except Latin America and the Caribbean. But even in this region, gains in hunger reduction have been reversed as a result of high food prices and the current global economic downturn (see background note).

This year, mainly due to the shocks of the economic crisis combined with often high national food prices, the number of hungry people is expected to grow overall by about 11 percent, FAO projects, drawing on analysis by the U.S. Department of Agriculture.

Almost all of the world’s undernourished live in developing countries. In Asia and the Pacific, an estimated 642 million people are suffering from chronic hunger; in Sub-Saharan Africa 265 million; in Latin America and the Caribbean 53 million; in the Near East and North Africa 42 million; and in developed countries 15 million in total.

In the grip of the crisis

The urban poor will probably face the most severe problems in coping with the global recession, because lower export demand and reduced foreign direct investment are more likely to hit urban jobs harder. But rural areas will not be spared. Millions of urban migrants will have to return to the countryside, forcing the rural poor to share the burden in many cases.

Some developing countries are also struggling with the fact that money transfers (remittances) sent from migrants back home have declined substantially this year, causing the loss of foreign exchange and household income. Reduced remittances and a projected decline in official development assistance will further limit the ability of countries to access capital for sustaining production and creating safety nets and social protection schemes for the poor.

Unlike previous crises, developing countries have less room to adjust to the deteriorating economic conditions, because the turmoil is affecting practically all parts of the world more or less simultaneously. The scope for remedial mechanisms, including exchange-rate depreciation and borrowing from international capital markets for example, to adjust to macroeconomic shocks, is more limited in a global crisis.

The economic crisis also comes on the heel of the food and fuel crisis of 2006-08. While food prices in world markets declined over the past months, domestic prices in developing countries came down more slowly. They remained on average 24 percent higher in real terms by the end of 2008 compared to 2006. For poor consumers, who spend up to 60 percent of their incomes on staple foods, this means a strong reduction in their effective purchasing power. It should also be noted that while they declined, international food commodity prices are still 24 percent higher than in 2006 and 33 percent higher than in 2005.

The 2009 hunger report (The State of Food Insecurity in the World, SOFI) will be presented in October.

Tornado

Posted by Troy on June 9, 2009

A tornado — one of at least five spotted across eastern Colorado on a stormy Sunday — damaged the Southlands shopping center in southeast Aurora and caused its closure, Business Journal reports.

What is tornado? What causes tornadoes?
A tornado is a violent rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of up to 300 mph. They can destroy large buildings, uproot trees and hurl vehicles hundreds of yards. They can also drive straw into trees. Damage paths can be in excess of one mile wide to 50 miles long. In an average year, 1000 tornadoes are reported nationwide.

Thunderstorms develop in warm, moist air in advance of eastward-moving cold fronts. These thunderstorms often produce large hail, strong winds, and tornadoes. Tornadoes in the winter and early spring are often associated with strong, frontal systems that form in the Central States and move east. Occasionally, large outbreaks of tornadoes occur with this type of weather pattern. Several states may be affected by numerous severe thunderstorms and tornadoes.

During the spring in the Central Plains, thunderstorms frequently develop along a “dryline,” which separates very warm, moist air to the east from hot, dry air to the west. Tornado-producing thunderstorms may form as the dryline moves east during the afternoon hours.

Along the front range of the Rocky Mountains, in the Texas panhandle, and in the southern High Plains, thunderstorms frequently form as air near the ground flows “upslope” toward higher terrain. If other favorable conditions exist, these thunderstorms can produce tornadoes.

Tornadoes occasionally accompany tropical storms and hurricanes that move over land. Tornadoes are most common to the right and ahead of the path of the storm center as it comes onshore.

Carbon Nanotubes Investigation

Posted by Troy on June 5, 2009

Carbon nanotubes have made a meteoric career in the past 15 years, even if their applications are still limited, ScienceDaily reports. Recent research results show that – apart from their favorable mechanical and electrical properties – they also have disadvantageous characteristics.

The scientists investigated carbon nanotubes both in their original state and in a state changed by oxidizing acids (such as a mixture of nitric and sulfuric acid). They found out that solutions of treated carbon nanotubes scatter light more strongly. “This is an indication that colloids have formed which do not settle”, Harald Zaenker says.

The researchers provided evidence for the first time that the heavy metal uranium, which is ubiquitous in the environment and, hence, also in the water, is particularly attached to the surface of treated carbon nanotubes. The scientists found out that the uranium uptake capacity is increased by an order of magnitude in comparison to untreated carbon nanotubes. “Therefore, it is plausible to assume that carbon nanotubes, if released to the environment, influence the transport of uranium in environmental waters and even in biological systems. The possible impact on the environment and on human health has in general been considered too little”, Harald Zaenker says.

On the other hand, the high bonding capacity of carbon nanotubes for uranium and other heavy metals also suggests using them for the removal of heavy metals from waters. However, they are not yet a cost-efficient alternative to classic water purifiers, Zaenker says. “Eventually, it is important to further study the behavior of carbon nanotubes in waters”, the scientist says. “Only then can the positive and negative aspects of carbon nanotubes be better assessed.”

The Time Of Green

Posted by Troy on May 11, 2009

In these uncertain times everyone agrees it’s the time for an economy modernization that can go through only on a close connection with a new look at energy perspective as an opportunity of solving today’s environmental challenges. It must be absolutely New Deal as Franklin D. Roosevelt said providing hard work to modernize America during the times of Great Depression. Source of energy we use will play 15-20 years from now and Wind Industry could become one of the most important energy solutions and an environmentally sustainable asset on the way.

According to a news report wind industry leaders and government officials visiting Record-Breaking Trade Show have continued discussion on the future of wind energy. Also good news is $93 million from the American Recovery and Reinvestment Act of 2009 will be used to support the development of wind energy projects. The fact is energy has not always been considered a national issue but the idea that a nation should have a clear-cut national energy policy sound obvious enough. Now all these old kind worlds must be tested in practice. It’s time for renewable energy, water desalination, fuel conservation in word and deed. It’s not just a vision of the future but ecomagination right now.
