Mexico Border Crossings - The Victims - The Wall by Ramon Cruz

Mexico Border Crossings - The Victims - The Wall is a free 22-page exposé with images and references that takes you to the border and gives you an intimate look at the reality of strife and panic as hundreds of people die every year and tens of thousands are incarcerated attempting to cross the border without authorization. Ramon describes how the border wall proposed by the U.S. Executive Office may actually save hundreds of lives and cut billions in immigrant detention costs each year (whether intended or not?) if it is successful in completely sealing off the border. All walls have two sides! Local involvement, advice and art from both sides of the wall is recognized as an important asset to a wall beyond borders, as long as the people take control. This wall project is opposed by many due to excessive costs and threats to several endangered species who normally migrate annually across the border in both directions. Ramon imaginatively describes several features he proposes that may aid in animal migration while selectively blocking human trespassers in an automated gateway. The costs of the wall construction may also be mitigated by adding solar panels and wind turbines and generating a surplus of electricity to plug into the grid. See blog.

Essay by Ray Cruz

On the Semantics of Evolution by Ray Cruz is a thought provoking essay on the meaning of traditional and new concepts for the evolution of species in the 21st century.  Learn how agriculture rapidly helps to create new species and cause the extinction of many others.  Examine the impact of biogenetics and the culture of war on evolution.  See how what each of us do in our daily lives affects evolution.  Read this excerpt from the introduction:

A definition of evolution from the Merriam-Webster Dictionary online includes this statement: “…a process of continuous change from a lower, simpler, or worse to a higher, more complex, or better state.” The etymology of evolution from the same source is “Latin evolution- evolutio unrolling, from evolvere.” We understand the evolution of species to be a gradual progression, one that normally takes thousands or millions of years to develop a new species from ancestral origins. What we see today, however, since the advent of agriculture, is a greater dynamic level of evolution, one that differs profoundly from pre-agricultural times. To better understand this new evolution of evolution we will examine and try to clarify the rudiments and semantics of classical evolution theory and the issues that abound from common terminology. We will also introduce some new concepts and terms that are needed to better understand human-manipulated evolution. The new concepts include super-intelligence, artificial selection, agevolution and a comprehensive, four-dimensional model of evolution.

Search Tool Tips:  After pressing the Submit or Submit Text button, a list of products, mostly free downloads, will be displayed and the Back button on the bottom of each page will allow you to refine your search to specific categories, manufacturers, price range, and more.  Adding more search keys will reduce the resulting selections.  Placing the OR argument between terms will increase the selection.  A blank space between keys is treated as an AND.  For example dandelion management OR dandelion control will give you documents and products related to dandelion management or control.  Enter dandelion tool for tools that remove dandelions.  The Ergonica Catalog Search Tool scans the entire description for keywords by default.  It will also include extensions to keywords such as longer words with the same root, therefore better results will be obtained by using the shortest word root for your key, in other words, enter tool instead of tools.  To jump start your refined search, go directly to the Ergonica Catalog Advanced Search Tool.
