Predicting the end of the world has probably been going on since man started thinking, whenever that was. It is warned about in Revelations in the Bible, so that must be about 2,000 years ago.

Nonetheless, it is the predictions of Nostradamus that are the most well-known and most abundant. Some biographical accounts of Nostradamus’ life assert that he was terrified of being persecuted for heresy by the Inquisition, although neither prophecy nor astrology fell under their jurisdiction. He would have been in danger only if he had used magic to support his prophesies.

In fact, his contact with the Church as a prophet and a healer were always very good. His short imprisonment at Marignane in late 1561 came about purely because he had published his 1562 Almanac without the prior permission of a bishop, contravening a recent royal decree.

Here then are a few of the prophesies of the ending of the world and the annihilation of mankind.

December 21st, 22nd or 23rd 2012 are all possible dates for the ending of the world according to the ancient Mayan Calendar.

Mycelium Running by Paul Stamets has been the perpetual best-seller on popular mycology since published in 2005. It’s an indispensible reference book for anybody working the land, especially foresters, farmers and environmental cleanup contractors. It’s also a great book for anyone interested in growing their own food mushrooms.

The book is a treasure trove of useful practical information on what Stamets refers to as mycofiltration (of water), mycoremediation (of toxic waste), and tips on how mushroom mycelium can help improve soils and boost productivity in farming and forestry with less use of pesticides and fertilizers.

For example, an easy do-it-yourself method of creating a mycofiltration bed for filtering waste water is delineated in detail. Recommended materials are listed along with suggested mushroom species to use and the ideal dimensions of the bed. In Stamets’ examples, these mycofiltration beds are used to effectively filter and neutralize farm runoff but they could also be used to filter industrial waste water.

Not only does it solve the problem of farm runoff and E. coli contamination of nearby streams, it can also yield highly palatable food mushrooms, and the bed itself can be dug out every 2-3 years and then used as an excellent fertilizer for the farm.

Although we all are familiar with air pollution, and know it is a very real problem that affects our environment and all of us, most of us tend to ignore it as if it does not exist. This is particularly easy for people who live in rural areas and do not see on a daily basis its extent: they do not see smog, factories, or millions of cars on the road polluting our air.

That being said, no matter how hard we may subconsciously desire to, there are times where we cannot ignore this problem. For example, when we smell the exhaust of cars when standing next to a road, or when we see factories pumping smoke high into the sky, it is hard not to think of the damage that is being constantly created.

What is air pollution? Air pollution consists of various types of chemicals and gases being passed into our atmosphere. The main cause of this unwanted pollution is vehicles. Second to to that are industrial factories that release dirty and dangerous fumes into the atmosphere.

Why is air pollution dangerous?

History reveals that the Hanging Gardens of Babylon is a big evidence of a hydroponic garden. Moreover, the Aztec Indians in the now Mexico had a system of growing crops on rafts. These rafts are in shallow lakes that you can still see in floating gardens near Mexico City. Therefore, history shows the great significance of hydroponic system of growing plants even in ancient times.

Developments with hydroponics did not however take place in Europe until 1699 when Woodward discovered it. He found out that he can grow plants in a solution of water to which soil had been added.

On the other hand, Liebig, a German scientist, originated using nutrient solutions to study the nutritional requirements of plants in the 1850’s. It was then followed by Sachs in 1860. Knop also did some studies of nutrient elements in water solutions in 1861. They grew plants in nutrients-rich solutions with mineral salts. This does away with the soil as a main requirement for growing crops.

Many researches on the nutritional requirements of plants extended through even until the 1870’s. By 1925, practical applications of hydroponics were being introduced for the vast development in the greenhouse industry.
