Think Globally, Act Locally

Kingsley Ogbonna
Profesor de Ciencias

En las clases de Ciencias de Kingsley Ogbonna, los estudiantes de 5° investigaron la manera en que el ser humano afecta e interrumpe el equilibrio del ecosistema. Después de estudiar las propiedades del agua y la importancia de las cuencas hidrográficas para el planeta, los nogalistas indagaron sobre un problema local y analizaron la contaminación que sufre el Río Bogotá a causa de las aguas residuales de los hogares y de las diferentes actividades industriales que lo afectan. Como parte de su trabajo, crearon los siguientes podcasts en los que hablan sobre las posibles soluciones para la restauración del Río.

The pandemic is making us realize the importance of nature and the services they provide to humans. During this academic year, the 5th grade students have dedicated their science classes to explore some of the ways human activities, what you and I do every day, disrupt the delicate balance in ecosystems. One of the ecosystems that is being devastated by our actions is the Bogotá River ecosystem. This is the most important river in the Cundinamarca department. According to figures recorded in the River’s “Plan de Ordenación y Manejo de la Cuenca Hidrográfica”, this ecosystem is home to 542 species of fauna, of which 322 are birds; 76, mammals; 66, reptiles; 55, amphibians and 23, fish. The conservation of this river should be a priority. Sadly, it is considered as an open sewer for solid waste and wastewaters. It is fast becoming a dead river. The River receives the wastewater from the homes of millions of people and from the different industrial activities, like the tannery industries near the source of the river in the municipality of Villapinzón.

After studying the importance of ecosystems, the special properties of water and the invaluable role watersheds play in the water cycle, the students worked in groups to create podcasts about the River. They want you to become aware of these problems and the possible solutions for restoring the River. We enjoin you to listen to them and be part of the solution.
