transgenicos
¿Qué es un producto transgénico?
Al decir transgénico, nos referimos a revolución genética, o estamos hablando de un organismo alterado mediante ingeniería genética; es decir, que ha sido creado artificialmente manipulando sus genes.
Aspectos positivos de los alimentos transgénicos:
Loa organismos modificados genéticamente llevan en sí, insecticidas o resistencia a herbicidas,mayor resistencia al ataque de insectos, asimismo aumentado su producción y minimizando el uso de insecticidas, también algo muy destacado es que estos organismos poseen mayor resistencia a condiciones ambientales y así también se manipulan las características físicas de los productos, para obtener el resultado deseado.
Aspectos negativos de los alimentos transgénicos:
Es que desconocemos lasconsecuencias de usarlos, riesgo a desarrollar nuevas enfermedades. A su vez, la eliminación de especies o la degradación genética, el empobrecimiento de la biodiversidad. Contaminación de los alimentos, del suelo y del agua.

Quienes nos oponemos al cultivo de organismos genéticamente modificados, no estamos condenando la investigación ni la tecnología en sí, sino el uso de la “ciencia sin conciencia”, parafraseando el artículo del profesor Víctor Toledo de la UNAM , en la discusión sobre los transgénicos.
Con unas cuantas palabras, el viceministro de Ciencia y Tecnología, Kéilor Rojas, lequiere dar vuelta a la tortilla y utiliza argumentos que, si se les analiza concienzudamente, no...
