Protect the ozone to safe the green

Ozone Layer and Montreal Protocol

Everything in this world is somehow covered in a sheath for protection. In same way the world is protected from the harmful rays of sun by a sheath of its own the ozone layer. But the bad news here is that it is depleting at an alarming rate of 4 per cent per decade.

This decreament in the content of ozone and thinning of ozone can cause sun burns, skin diseases, skin cancer, cataract and other eye diseases, infections and reduces immunity of human bodies, decrease in growth of vegetation and plants, loss of nutritional values and danger to sea life and ecosystem. Refrigerators, air conditioners, perfumes are the substances, that are having the choloroflorocarbon, are the culprits of this awful crime.

Ozone in upper enviroment works as a protection of the world but at ground level, ozone can be unhealthy—in fact certain factors of it mix up and forms a dangerous element called “smog.” Smog formation requires three ingredients:
             1) Nitrogen oxides, which come almost from man-made)sources such as automobile exhaust and power plants and all smoke producing things.

            2) Sunlight; and

            3) Volatile organic compounds (VOCs), both naturally occurring and man-made.

The main ODS (ozone depleting substances) that has been highlighted in  the Montreal Protocol are chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, carbon tetrachloride and methyl bromide. However with increasing awareness,  the global consumption of ODS has been reduced by some 98% since countries has started to  take the Montreal Protocol on a serious note. And in lights of that the atmospheric concentration of the most aggressive types of ODS is reducing and the ozone layer is showing some recovery. Nevertheless, it is not expected to recover fully, even if same protocol is followed, before the second half of this century.

Keeping Safe during Thunderstorm Conditions

We know how scary and intense thunderstorms can be when they come, especially during storms. They happen every now and then around the world – happening about 16 million times yearly, and lasting for about 30 minutes on the average.

In keeping yourself as well as your neighbors and family members safe during a thunderstorm, there are guidelines that should help you.

Usually, the first thing you have to do is to be updated on the happenings around your neighborhood. You can follow events online, by phone or by accessing what is happening outside by yourself. These days, a lot of severe weather conditions are monitored with accuracy, so you can follow the news for updates about the direction and movement of the storm.


Cover and secure all outdoor appliances, because debris can be as risky as electric shocks and lightning. Inside the home, stay away from windows and doors as well as electrical appliances as the storm passes. In fact it is best to have all of the electrical appliances unplugged from the sockets.

It is important to unplug electrical appliances because lightning can actually travel through the wires and cables. Also avoid the phones and leave sockets unplugged from electric current except where it is necessary.

These steps can help you avoid thunderstorms as they pass by your house. Sometimes they could last longer than normal, but you have to give a time frame of about 10 minutes after the storm before going out of your safe haven.

How Technology Can Facilitate Disaster Warnings

Imagine receiving an alert through your phone from the Environmental Agency of an impending flood, with the capacity to destroy the buildings in your neighbourhood. You get your family ready, and together with your community, you move to a safe location.

Now that is how mobile technology intends to provide aid and alert to coastline dwellers of natural disasters. The issues regarding flooding have led to the need for a radical improvement in the way floods and other natural disasters are forecast.


People use their mobile devices more these days as a convenient source of information. The Nielsen research group showed that there has been an 85% rise in mobile app development, an 82% growth in mobile websites as well as a reduction of 4% in the use of the conventional personal computer.

This means that mobile apps can be used by people to get alerts to disaster-related information in their community. Research has also shown that the use of mobile apps has more than doubled. And recently, the Environmental Agency introduced the very first Facebook flood warning system. Thus they have made flood alerts a priority in this period full of unexpected and sudden environmental disasters.

Going by Moore’s law that suggests that the power of technology doubles every 18 months, it has become a sector that cannot be ignored. This is true especially in managing the continuous natural disasters that occur in our cities today. We really need to adopt this innovative mobile technology in protecting people and their homes from unexpected natural disasters.

How Eco-friendly is Wind Energy?

There has been so much rave about eco-friendly ways of generating energy in our world today. One of such is by using wind turbines that are powered by high currents of wind.

On close observation of how tapping energy from wind occurs, one begins to wonder if it doesn’t go contrary to the whole essence of green energy production.

First, the fact that wind is not available at every point in time keeps the turbines idle at these times, making them unreliable. Sometimes too, when the wind comes, it could come with such velocity that the turbines will be turned off, so they don’t catch fire and disintegrate.


Also, as long as we are concerned about our environment, we have to take note of the birds and bats the rotating blades of the turbines kill at every point in time. Not to mention the uncomfortable sounds it produces when it is rotating. The sounds have damaging effects on mammals especially.

As for emissions, the concrete base and towers of steel produces a lot of carbon dioxide emissions into the environment. This doesn’t mean greenness in any sense.

Furthermore, costs of maintaining a wind turbine is high. Each of its motor lasts just for 10 to 15 years, including the costs involved in installing its transmission lines.

So there needs to be a reassessment of how green the energy produced by wind technology really is. There has to be a way of minimizing its negative impacts in the environment, or reducing its general maintenance costs.

Earth’s Future Climate – Hopeful of Bleak?

Over the years, we have seen our beautiful world suffer from serious emissions that have threatened the natural beauty of our environment. The emission from the earth has contributed to the warming of the earth’s climate.

Scientists have already projected that if the emissions persist, then we could see the earth’s temperature increasing up to an additional 4 degrees later in this century.

So are we doing enough to stem the tide? The truth is that if tough decisions are not taken quickly and drastic, then we’ll soon be living in crises mode.


Feasible ways of halting climate change:

The United Nations Environment Programme (UNEP) discovered that by 2050 the emissions from the earth need to be about 50% below its current levels; in their Emissions Gap Report of 2012. So, how can this gap be closed up?

There has to be total compliance with every agreement regarding reduction of green house emissions. The UNEP and other bodies concerned have to implement policies that not only go a long way to achieving emissions objective; but that are also interesting for the concerned nations to pursue.

Take for instance, implementing a better performance standard for public vehicles and buses, will obviously bring down carbon emissions, benefit the environment and enhance quality of air in cities.

Also, there has to be concerted effort in helping under-developed and developing countries adopt a low carbon economy. This can be achieved through quality policy making, and creative information technology systems.

Japanese Tsunami Trash Reaches the US

In March 2011, an earthquake off Japan would cause a tsunami ready to sweep over the islands. 15 000 deaths reported, caused a nuclear disaster, and millions of tons of debris carried by the ocean who is retiring after having submerged lands.

In a previous article, we relayed the fear of U.S. authorities to see washing up on beaches on the Pacific coast of the remains of some 20 million tons of trash carried by Japanese tsunami waves. To get an idea of the magnitude of the thing, we refer to the photo at the top of the article.

The United States believed that the waste would reach their shores in 2013, but this week is a buoy that was found in Washington state after traveling over 7000 kilometers at sea Coastal States may now prepare for a more massive arrival of such “surprises”.
