Are there any pollution-free places left on Earth?

This article, titled “, Are there any pollution-free places left on Earth?” had been written by Rachel Nuwer in the previous year however it is still very actual and unfortunately will be actual for long.
So, read it, learn it, make up concluding and start thinking about.

Humans appear to have done a thorough job of contaminating the Earth’s rivers, oceans and atmosphere, says Rachel Nuwer. Is there anywhere pristine left on the planet?

Comments Off on Mexico Volcano Eruption

Mexico Volcano Eruption

Mexico’s spectacular Colima volcano eruption captured on webcam:

The active volcano is located approximately 500 kilometres west of the capital Mexico City and has erupted at least 30 times since 1585.
The vision was recorded on a permanent fixed webcam operated by Webcams De Mexico, which had placed a series of cameras in the area since the volcano’s last major eruptions in 2013 and 2014.
Colima experienced several significant eruptions in the late 1990s and scientific monitoring of the site began two decades ago.
Ash fell on towns up to 25 kilometres away from the volcano, but no lives or properties were under immediate threat.

HVAC system

Today people depend on heating and cooling system (also known as the HVAC system) very much. Whether during cold winter nights or sweltering summer days HVAC is the technology which can make our life more comfortable and pleasant. So we depend on it at every step – being at home, at work, driving an auto.

Nearly half of a home’s total energy expenses go towards heating and cooling. That’s not surprising, especially I you’re living there where outdoor temperatures are either too cold or too hot most of the time to even think about keeping the windows open.

High efficiency, low heating and cooling costs

According to the U.S. Dept. of Energy, an older furnace or boiler operates with an efficiency of 56% – 70%. A new, high-efficiency furnace can operate at 96% efficiency. Depending on the cost of fuel and electricity, an upgrade to a high-efficient HVAC system can pay for itself in just a few years.

HVAC systems are classified as either self-contained unit packages or as central systems. Unit package describes a single unit that converts a primary energy source (electricity or gas) and
provides final heating and cooling to the space to be conditioned. Examples of self-contained unit packages are rooftop HVAC systems, air conditioning units for rooms, and air-to-air heat pumps.

With central systems, the primary conversion from fuel such as gas or electricity takes place in a central location, with some form of thermal energy distributed throughout the building or facility. Central systems are a combination of central supply subsystem and multiple end use subsystems. There are many variations of combined central supply and end use zone systems. The most
frequently used combination is central hot and chilled water distributed to multiple fan systems. The fan systems use water-to-air heat exchangers called coils to provide hot and/or cold air for the controlled spaces. End-use subsystems can be fan systems or terminal units. If the end use subsystems are fan systems, they can be single or multiple zone type.

Once the ideal comfort conditions for a building have been identified, good controls can help maintain these conditions.

Birds Fried in Midair by Solar Plant

A new solar “mega-trap” in the middle of California’s Mojave Desert is not so green as we thoight, because it is killing the avian lot at a rate of up to one bird every two minutes, according to the U.S. Fish and Wildlife Service (USFWS).

The state-of-the-art Ivanpah Solar Electric Generating System (ISEGS), which opened in February, is the world’s largest solar plant to utilize “power towers”. It contains of the $2.2 billion plant, which launched in February, is at Ivanpah Dry Lake near the California-Nevada border. More than 300,000 mirrors reflect solar rays onto three boiler towers up to 40 stories high.

Water inside is heated to produce steam, which turns turbines that generate enough electricity for 140,000 homes. The new plant would have towers up to 75 stories high. Federal wildlife officials said Ivanpah’s bright light might be attracting insects, which in turn attract insect-eating birds. But Ivanpah officials say at least some of the puffs of smoke mark insects and bits of airborne trash being ignited.

Eco batteries

Ecology is one of the most important things people have to keep and in the light of this problem searching a new way of getting energy for future power generation. According to BBC a Japanese electronics firm has shown off a vibration-harvesting generator that could replace standard batteries. “It’s great because they will work OK in a low-power application for AA batteries that one can shake without breaking; a remote control, for example,” Carl Telford an analyst at electronics business consultants Strategic Business Insights told.

“Of its size, it is small, compact, and directly compatible with existing power sources. Brother says that it can produce enough power at reasonably low frequencies, around 4-8Hz – this is impressive.

“Walking with a device in your pocket would vibrate with a frequency of around 2Hz. You’d need to shake the remote quite briskly, but it would work.”

There are no plans to commercialise the batteries as yet. “Currently the cells are still in the trial phase and so far we do not have a clear business plan for this item. However, we will continue to monitor the market to make a business plan when needed.”

Water and Climate

The climate is changed and a lot of things related to that is inevitable and must be considered by governments right now to take a number of steps to limit emissions and save water.

You know, many years ago I had read in some of newspapers that in future people have to buy clear water, packed in bottle in a shop then I remember that I could not imagine how it can be at all!

So now we have what we have – we buy clear water in a store, we have the changed climate, changed world and the most important the clear watet which is one of the based staff of life is a truly biggest world’s problem today. As you know, no water, no life. It is essential for all dimensions of life., it’s not necessary to life, but rather life itself. Every scholar knows that whater is H2O, hydrogen two parts, oxygen one, but actually nobody knows what that is.

Why am I writing about again and again? Because the facts are still unconsoling:

1.1 billion people don’t have safe water and 2.6 billion lack basic sanitation.
Source: Human Development Report

Dirty water and poor sanitation account for the vast majority of 1.8 million child deaths each year from diarrhea – almost 5,000 every day – making it the second largest cause of child mortality.

We have to adopt to the new reality.

Eco Gardening Solutions

Green gardering advices

Interesting and looking for green gardering advices I’ve found 250 Tips for an Eco Lifestyle book FROM the Little Green Book series where I found answers on most of my quastions. If you want to learn how to make choices that affect not only your own life but the planet as a whole, this is for you. The Little Green Book of Gardening contains 250 tips on such subjects as organic growing, lawn care, wildlife gardening, gardening power and products, water and garden waste. Theres great advice on everything from the ins and outs of watering your lawn and digging your garden green to making your own compost and practising green pest control. Be sure you can buy tthi useful book online, on right now for $10 only.

Environmentally friendly solutions

Here is some of cost-efficient and environmentally friendly solutions for eco-gardening and large-scale landscaping projects, offered by the Environmental Protection Agency.

Good conservation

Make your garden a place for good conservation and environmental savings, getting economic at the same time. If yard waste is managed properly, a garden environment can not be enhanced but also help you save money.

Use shredded untreated wood and leaf wastes converted into chips as mulch on garden beds. This would help prevent weed growth, retain moisture, regulate soil temperature, and add nutrients back to the soil

Recycled materials

You can use recycled materials – like wood scraps and cardboard – for building a backyard fort or tree-house for your children, giving them an eco-friendly atmosphere.

Purchase recycled-content gardening equipment and tools. Some fo such equipments are like,

garden hoses made from old tires.

stepping stones made from old glass bottles.

hand tools made with recycled plastic.

plastic lumber made from recycled plastic bottles and bags — to make flower beds, trellises, decks and birdhouses.

Recycle used oil and tires from lawn and garden equipment.

Gardening equipment

Maintain your lawn mower and other gardening equipment regularly. Always keep them in efficient operating condition. When refilling your lawn mower, use a nozzle that prevents fuel spills and get wasted unused. To save fuel and protect the air quality, use manual tools.

Don’t bag the grass clippings; leave them on your lawn instead. You can also use a mulching mower. The clippings will return nutrients to the soil rather than take up space in landfills.

Protect young seedlings

Protect young seedlings from frost, wind, heavy rain, and roving animals by reusing plastic milk jugs, just by cutting the bottoms off, or else use small paper bags for the purpose. And, once the seedlings have grown, recycle the bags and jugs for sure.

Donate healthy plants to community gardens or schools, or gift them to neighbors.

Introduce ladybugs as they will eat aphids.

Plant marigolds to ward off beetles.

Look for quick-sprouting plants that help block weed growth.30647
