A Review of Beyond Oil, The View From Hubbert's Peak  
by Herbert Young


It has long been known by geologists that the world's oil supply is finite. Oil is not a renewable resource and it is found in relatively limited geological environments around the world. This is the subject of Beyond Oil, The View from Hubbert's Peak, by Kenneth S. Deffeyes, Professor Emeritus at Princeton University published in 2005, (202 pages, hardcover, Hill & Wang).

In general oil is found in a zone called the oil horizon located between 7,500 feet and 15,000 feet below the surface in organic rich sedimentary formations. Deeper than that, the temperature of the rock is too hot for oil molecules to stay together, and above that the hydrocarbons are not heated enough to separate into crude oil. Sandstone, dolomite and limestone form virtually all the host rock for oil production in the world and comprise only about 1% of the world's rock formations. In addition, specific geologic structures are required to trap the oil. According to Professor Deffeyes, seven specific criteria are required for oil to be present in a particular location. Without any one of these criteria, oil is not present, period.

While Saudi Arabia has the largest annual production of oil, the United States and Russia are second and third place according to Deffeyes. Saudi Arabia has 1,560 producing wells, Russia 41,192 wells and the United States has 521,070. The United States is one of the most drilled and explored places in the world.

Between 1901 and 2005, oil use and production consistently increased, first in the United States and then in the world. In 1956, M. King Hubbert, American geologist and geophysicist, predicted the United States oil production would peak and then start to decline by the early 1970s. When his predictions came true, Hubbert became an instant folk hero among energy conservationists. This became known as Peak Oil or the point when annual production of oil reaches a maximum and then starts to decline. It can be diagrammed as a bell shaped curve with a peak at the top.

Hubbert then turned his calculations on world oil production and supply. His methods worked the same way predicting the world oil supply as they did with the United States supply. Essentially, world oil production peaked early in the 21st century according to Hubbert.

Professor Deffeyes worked with M. King Hubbert, and explains in detail the process that Hubbert used to make these predictions. He discusses both oil and natural gas and the implications of being on the downward side of Hubbert's Peak. While Hubbert used some very complex mathematics in his initial calculations, Professor Deffeyes explains Hubbert's calculations using relatively simple mathematics. In fact, simple algebra forms the basis of his analysis and it is understandable to many with a basis in high school mathematics.

There is a lot of information and disinformation about renewable energy. This book discusses many of today's energy sources and those of the foreseeable future. It dispels many of the myths and disinformation about energy so glibly passed around by a largely uninformed public, self serving political leaders and a media hungry for ratings.

Because oil has played such a large part of the world's economy, it is in everyone's best interest to become informed about energy supplies and sources. Energy fuels such as coal, geothermal, uranium and many of the so-called alternative energy sources all will be impacted by the declining amount of oil available on the downward side of the peak oil curve. This book is a must read for anyone interested in learning more than the common platitudes about energy and, in particular, oil.

How to Stop Deforestation?  
by Jean Simmer


Deforestation has rapidly destroyed much of the planet's forests for years. One major challenge for governments and environmentalists alike would be how to stop deforestation so current environmental conditions would not come to worse.

In the past centuries, people have been naturally cutting down trees and burning down forests. Take note that hundreds of years ago, most of the earth's land surface had been covered by forests.

So to be able to construct residential areas and establish villages, people had to destroy some forests. As population grew through the years, there are much development that needs to be achieved.

Poverty and over population had rapidly caused alarms to governments around the world. People in the past decades had been troubled at how they could generate earnings to feed themselves and their children.

Agriculture once was the principal source of families' incomes. But people grew impatient. Until the middle of the 20th century, people had readily embraced industrialization, which was touted as the easy way out to poverty, employment and slow production.

Surely, development was spurred, jobs were created, new industries emerged. But something had to give in. In exchange to the fast budding of factories and different industries, forests were depleted.

Since the Industrialization revolution, the total forest covers of the earth has drastically lessened. Biodiversities were affected, and overall climate changes and environmental denudation were spurred.

It is now time to slow down or eliminate deforestation. Stopping deforestation would be easy if people would just cooperate with one another in that single initiative.

Stopping deforestation

Indeed, environmentalists and forestry advocates have been reminding people and governments to immediately act on the problem regarding continued deforestation practices all around the world.

Deforestation could be slowly stopped if people would be more environmentally conscious. That means, to accelerate efforts in stopping deforestation, initiatives have to be started by you.

As a suggestion, the significant contribution you could do is to help curtail the demand for products that are reliant on deforestation. It does not necessarily mean that you would boycott products.

It means that you could start by advocating and participating in recycling programs. Paper is made from barks of trees that are in turn, mostly coming from forests. Did you know that you could recycle paper?

There are industries that are focused at recycling paper. Old and used paper would just be processed and turned into new paper products. If the practice becomes wide-scaled, the number of trees that has to be cut down would be reduced.

Stopping deforestation practices

Governments around the world should also start implementing legislations that would effectively prevent the continued practice of deforestation. Sanctions should be given to violating parties. That way, there would be less people and companies that would engage in slash and burn practices.

Rain and dry forests should be protected by governments. They can be declared national properties, so no businesses can ever touch them. They can also be turned into national parks; thus, the overall state of these forests could be effectively preserved.

Reforestation

Reforestation is the opposite of deforestation. If deforestation can be considered wounding of nature, reforestation is the sought-after healing process. In reforestation, forests are replanted with trees. In years, the forests would be much alive again.

Since the practice of deforestation in some cases could not be avoided, it can be regulated so as not to create negative impact to the environment and to biodiversity.

Deforestation could be slowed down. To do this, trees could be cut at slower rates. For each cut tree, a new one should be replanted. By that, logging activities would not be entirely scrapped, and at the same time, forests are renewed.

People should also stop denuding mountains and forests so they could establish new villages or use the land for other purposes. There are special cropping techniques that would enable planting of crops within forests. The concept of intercropping is not very familiar, but would be of great help to anti-deforestation initiatives if taken seriously.

If people do not act immediately to curb deforestation for good, experts estimate that in 30 years time from now, the earth's surface would be left naked, without forests.

Catastrophic changes would be felt through harsh weather conditions, flash floods and landslides. The earth's geographic surface could also be altered due to adverse weathering caused by climate changes and the absence of natural soil protection.

Help stop deforestation now before it becomes too late.
