Biodiversity

Biodiversity is a word that comes from the Greek that means bio life and diversity well different, so it means different living organisms or as the definition says it is the Variety of life in an area that is determined by a number of different species in that area (Biggs et al, 2009).

In México de Biodiversity is very important because of the size of this American country, which contains a huge variety of different ecosystems and with it species and landscapes. For this reason in México the government created a special organism to take care of the biodiversity in the complete country and in each specific situation, this was named the Conabio.

Since the Conabio creation has been the collection, management, analysis and dissemination of information of our biodiversity the main aim of it. Such information is essential for making decisions regarding the use and conservation of biodiversity supported by scientific knowledge. To collect, organize and distribute this information is the National Biodiversity Information established (SNIB) of Mexico. (www.conabio.gob). So the importance of the biodiversity in the biosphere is to be aware to affect the other ecosystems with the actions of the humans by being excessive with the hunting, recollection and the interaction with other species, so in order to maintain an stability between species and ecosystems we need to take care of the balance in the biodiversity.

The Biodiversity is very important for humans because of the routine or circuit in their lives. Day by day the humans interact with the environment with the different activities. In México approximately the 40% of the population is dedicated to the Primary Economic Activity; this means get the main matter from the nature so later it can be transformed into an other object for example México is the number 1 in extraction of silver and also in transformed it into jewelry. In Yucatan the 3.6% of the PIB in the state is provided by the agriculture, the forestry and fishing. (http://www.sefoe.yucatan.gob.mx).

This is an important number and it has a reason of being that amount. If the people who practice the fishing in Progreso start fishing more lobsters that the necessary it will have a huge repercussion to the sea ecosystem, the food chain is perfectly adapted so the organisms can react in a certain way giving a balance to the ecosystem, that is why the fishers have an specific season in the year to fish certain species as Octopus Season, Lobster Season, and Sea-Snail Season. The organism that is in charged of giving the dates for the Seasons in Yucatan is the Conapesca from the Sagarpa. This organism says that the reason of the seasons in the fishing is that the fishers should give time to the species to reproduce and basing the season on their studies of how long it takes to the species to reproduce and to grow enough for its marketing. (http://www.conapesca.sagarpa.gob.mx/wb/)

In my opinion the best way of preserving the biodiversity is to have limits and specific laws that can help the people who is dedicated to this type of Economic Activity not only in Yucatan, also in each state depending on the environment of each region and state. For example in Yucatan as a solution to the huge damage that the hunters have done to the Deer in the state, the government should build and organize real reserves for the deer, the capybara, the hare and other animals that have been damaged in the population number and the food chain in each of their habitats. In Mexico there is a lot of freedom for the hunters who hunt in exes so they can sale the four, the deer feet, meat and other elements of the species they hunt. As well the government thinks that the ecologic parks as “The Centenary Zoo-Park” and now “The Animaya” are enough but they do not understand that it is just a Zoo – Park, not an Ecologic Reserve with all the needs of the species, to stay wild but at the same time to have bets and all the cares the animal need.  Also more studies to each species of animal and plant so we all can be in harmony with all the diversity of organisms. Everything in excess is harmful, some laws were done to respect no to punish.

PBL# 1 Sickle Cells Disease.

PBL # 1: Sickle Cells Disease. A Study Case

  The Sickle Cells Disease is a type of anemia that affects directly to the red blood cells , making them abnormal, instead of being circle cells the red blood cells affected by the genetic disorder look more like a half circle or a water drop shape. This means that the red blood cells affected by the Sickle Cells Disease are more fragile than the healthy ones, and this makes the cells less flexible and easier to break.  

  The biology is the science that studies living things, as one of these objectives is the study of cellular basis of living things. This means that the biology is the science that is in charged of studying this disease, its origin, what causes it and how to manage it in people and stop the abnormality in the red blood cells to have less cases of the disease.  For this the people who study the disease use different sciences to have a conclusion on the sickness. The sciences used for the investigation are:

·         Chemistry: studies the molecular structure of the healthy red blood cells and the abnormal ones to compare them and notice what affects the cell behavior and shape. As well the effect of the disease on the hemoglobin the protein that carries the oxygen in the blood.

·         Physics: studies some of the properties and interaction of matter. So scientists use physics to understand red blood cells behavior and flexibility during their travel around the body and why they break during their travel.

·         Mathematics: Is the science that studies numbers and formulas. In other words all the things that has to do with numbers. This science is useful in this study to write the information and quantity for the study. As an example to know how many red blood cells are affected and the percentage of it compared with the complete quantity of blood.

·         Geography: This science that studies the region and its characteristics as demography (people). The geography is useful to know how many people are affected by the disease, which particular affects to afro American people and Caribbean people.

·         Computer Science: this science is focused on the technological management of data. So for the study of sickle cells disease scientists make up data bases to control how many people have the disease, why and also for other technical studies. Gather information and inform people about it.

·         Ethics: The ethics are very important in the management of people with these abnormal cells, because they have the bad genes that are inherit to their sons and it continues the mutant cells. The ethics are useful to know what to do with this people, to let them abort babies, to let them just adopt or what to do to with the sick people to stop the disease.  

The biology is the main science that studies this sickness but it also uses different branches of biology so scientists can focus on a specified topic and not in a general way. For this specific disease the biology branches used are: anatomy, a little bit of astrobiology, biochemistry, biogeography, biomedical, cell biology, chorology, endocrinology, genetics, molecular biology, and infectious diseases.

During the process of the disease a lot of levels of organization of matter are affected. This starts with the molecule which change the way phosphorus and nitrogen are arranged and this affects the cells that take an abnormal shape as a long cell or as a long leave, this affects to the blood because the red blood cells are nor normal and don’t have the enough oxygen for the body, and all this affects to the complete body cause it makes the blood chipper of oxygen and easier to break and to have cancer in the blood or a type of anemia which all this affects to a part of the population, people die because of the anemia so it is a domino effect, from the molecule to the population.  

In the Sickle Cells Disease the mail problem is that the macromolecules of the hormone of the hemoglobin is affected when it is formed making a weird shape structure without spaces between them so it makes the molecule less flexible and this affects the complete structure. This affects the molecule when it badly arranges itself, then the second level of structure when it forms a worm shape instead of a helix shape, and the third level when it joins with another molecule it makes a mutant red blood cell.

The sad part of the story is that the sickle cells disease is very common and most people that have this problem don’t even know that they have it. So nowadays the governments of different countries are making social movements to introduce and inform citizens about the disease and how to prevent it. Also in some countries the government is thinking about making a law that does not aloud people with this type of anemia to get married and have children. Other solutions are the adoption and the artificial insemination.

In conclusion this is a very serious problem for the society and we need to take care about it and stop the disease for the wellness of the citizens and the people in general.

Also I completely love Apple products as the MacBook, iPod, iPad, iPhone, etc. I like biology a lot, as well history, math and sports. I practice Tae Kwon Do and some x-treame sports but as hobbie.I would like to be a great bussines man and to have a lot of corps or work as a movie/clips/adds producer. I spend a lot of time wathching some videos from certain "Youtubers" in english most of the time, as Ray William Johnson, GWabir and some in spanish as Dada88. I want to study something about graphic design and movie productions. Well this is everything for today and follow me, I guess. Bye bye and take care. :)
