Childhood Obesity Prevention. Massachusetts

2 November, 2017


    In a survey conducted by Massachusetts Public Health Association (MPHA) it was requested information on which types of the following school recreational facilities were available: playground, sports field or gymnasium. As a whole, the answers were: 61% had a sports field, 67% had a playground, including middle and high schools, and 89% had a gym. Schools from higher income communities are better-equipped with exercise facilities. Read the rest of this entry »


How is poverty lived

28 October, 2017

   In my day we did not have today’s resources; we barely travelled, means of transport such as motorways were those of pre-civil war. There was no television, or mobile phones, etc. Illiteracy was still a scourge. Read the rest of this entry »

Abortion Again

26 October, 2017

   I confess that I don’t understand Pro-choice people. What moves them to defend as a right that a woman aborts her son? Sincerely, the assumptions on which that right is based on are so incredible that it is difficult to refute them. In 1985 in Spain, abortion was legalized in three assumptions: violation of women, risk to the physical health of the mother and the fetus, and risk to the mental health of the mother. That means that abortion stayed offense, but if it was practiced in one of these assumptions, neither the mother nor the person who would help her could be tried. In fact, more than a decriminalization, it was legalization. Some clinics (“abortion centers”) appeared. There and for a price more or less high, reports were issued, usually false, to declare that the pregnancy was very dangerous for the mental health of the mother; and then she could abort. A Danish report on spanish clinics showed that fetuses that even had seven months or more were aborted. For this, it was only necessary to falsify the supposed age of the fetus. Not happy with this situation, and as a result of a research on the clinics of Dr. Morin, where were executed real slaughter, grinding fetuses, and omitting the permissive Spanish legislation; the socialist government of Mr. Zapatero enacted the Organic Law 2/2010 on Sexual and Reproductive Health where abortion becomes a right, and assumptions no longer would be required in the first fourteen weeks. The will of the mother will only be required; the father has nothing to say because the son is only of the mother but if she decides the contrary then the father must be responsible in his fatherhood ¡Curious legislation! I will no take under considerations that law, and especially what has been said in favor and against it. Read the rest of this entry »

A great number of negligence caused the accident of the oil tanker Exxon Valdez on March 24, 1989 in Alaskan waters. It left the port of Valdez, loaded with crude oil and crossed the Straits of Valdez when the disaster occurred. The tanker was in an area where the radar system was obsolete; therefore, there were shadow areas. Thus, ships that cleaved these waters sometimes could not be located. Likewise, because a permit was needed to navigate there, that night the captain left the command of the ship to a pilot with no experience in that area.

And the tragedy happened: the oil tanker crashed into an iceberg. It opened a huge way in the single hull and began to spill oil.

The Coast Guard was alerted. The oil tanker took responsibility due to the aid delay. At first, physical barriers were applied, but due to the stain was very extensive chemical dispersants were applied. This was a technique never used before and for that reason it did not work.

The best way was to use fire. This greatly reduced the extension. However, the natural disaster was made and thousands of animals died in those nauseating waters. Rescue teams did what they could. They cleaned animals with soap, but it did not work much, because these animals washed themselves and swallowed toxic substances.

The consequence of this natural disaster was the human disaster since inhabitants supply with sea-products. Thousands of families run out of fishing for seasons…

This account is a brief description of what happened in one of the biggest man-made environmental disasters. And all was caused for a number of human negligence. It was the consequence of a bad or half-assed job.

Environmental and human ecology

11 October, 2012

   Currently, there is much talk about ecology and protection of the environment, especially after the international debate of Copenhagen. We might say that ecology studies the relationship between living organisms and their environment. We can make a clear distinction between natural and human ecology. Environmental ecology leads us to the protection of nature in all its facets. We are saddened when forest fires destroy the natural beauty and economic assets of forests and when plastics, cans and other wastes are throw on the streets. Read the rest of this entry »
