La exposici??n directa a metanfetaminas y otras drogas il??citas provoca adicci??n en las truchas salvajes, lo que compromete su reproducci??n y alimentaci??n.<\/h5>\n\n\n\n
La prescripci??n siempre representa un duelo personal. Asimilar el hecho de que necesitamos consumir alg??n tipo de f??rmaco para recuperar la estabilidad<\/strong> de nuestro sistema nervioso compromete<\/em>. Aunque los f??rmacos pueden ser la soluci??n a nuestro problema, los alicientes ecol??gicos de este consumo han tra??do consecuencias en la vida del planeta, antes ignoradas. Algunos peces ya son adictos a las metanfetaminas<\/strong> arrojadas a los caudales fluviales, como consecuencia de la contaminaci??n que estos generan al entrar en contacto con ellos.<\/p>\n\n\n\n

De acuerdo con el??Reporte Mundial de Consumo de Drogas??de Naciones Unidas, un aproximado de??269 millones de personas al a??o utilizan alg??n tipo de f??rmaco<\/strong>. Al mismo tiempo, la misma cantidad de poblaci??n secreta estas sustancias, que eventualmente llegan por el desag??e a los cuerpos de agua dulce. Es ah?? donde interact??an con las especies que ah?? habitan.<\/p>\n\n\n\n
A diferencia de lo que podr??a creerse, las plantas de tratamiento de aguas no pueden filtrar??estas sustancias nocivas para la vida silvestre<\/strong>, seg??n un??estudio??realizado en la Rep??blica Checa. De esta manera, una vez que los residuos llegan a los r??os y aguas costeras, las especies que habitan en esos ecosistemas??no cuentan con una barrera que les permita tener agua purificada<\/strong>.<\/p>\n\n\n\n
Los investigadores consideraron espec??ficamente el caso de la trucha marr??n salvaje, notablemente afectada por la exposici??n a metanfetaminas en el r??o<\/strong>. Las concentraciones de estas drogas il??citas en las aguas les han generado una poderosa dependencia, seg??n la evidencia recopilada directamente en los cerebros de los animales<\/strong>.<\/p>\n\n\n\n
Una dependencia dif??cil de superar<\/h2>\n\n\n\nFoto: Getty Images<\/figcaption><\/figure>\n\n\n\n
Para el??estudio, los cient??ficos tomaron a algunas truchas marrones en un acuario controlado. Inyectaron al agua??cantidades moderadas de metanfetaminas durante ocho semanas<\/strong>, para observar los posibles cambios en el comportamiento de los ejemplares al exponerse a ellas. Luego??la retiraron de golpe<\/strong>, para ver c??mo reaccionaban.<\/p>\n\n\n\n
En un espacio de 10 d??as, los peces no recibieron la sustancia para nada.<\/strong> En un tanque diferente, observaron a los animales que nunca hab??an estado expuestos a las drogas. Result?? ser que aquellos que s?? hab??an estado en contacto prefer??an el agua contaminada<\/strong>. No s??lo eso: se dieron cuenta de que, durante el tiempo de abstinencia, se mov??an menos y padec??an de estr??s elevado.<\/p>\n\n\n\n
Este comportamiento se observa tambi??n en los seres humanos que tienen que vivir sin la sustancia durante periodos prolongados de tiempo. El cuerpo la demanda<\/strong>, a pesar de ser nociva. Parece ser que el organismo humano no es el ??nico que responde as?? a estas drogas il??citas. Por el contrario, el problema es similar en otras especies<\/strong>.<\/p>\n\n\n\n
Espec??ficamente en el caso de las truchas, los investigadores se dieron cuenta de que la adicci??n les generaba apat??a y desinter??s por sus actividades habituales. Incluso alimentarse y tener relaciones sexuales??parec??a haber dejado de serles motivador<\/strong>. Por tanto, la exposici??n a metanfetaminas por la contaminaci??n fluvial compromete la persistencia de la especie, ya que afecta sus dos est??mulos vitales primordiales:??comer y reproducirse<\/strong>.<\/p>\n\n\n\n
