- [Presenter] As the world's demand for meat rises, insects, yes, insects, could be a good alternative. More than a fourth of the world's population is already eating them. Beetles are the most consumed insect, but more than 2000 edible species have been cataloged. And if you can get past the yuck factor, here's why they're a smart option. Insects are a healthy food source with a high protein and fat content. Crickets, for example, have about the same percent as most meat products. Because they're cold blooded, insects and fish require pound for pound less food to grow than birds and mammals. In fact, crickets are 12 times as efficient as cattle. This would allow insects to help meet the demand for protein while having a minimal environmental impact. Most farmed insects are now used for animal feed, but commercial farming for human consumption is in the works. The main challenge is to make production less costly and more efficient, and industrial systems are already being developed to tackle this. On top of providing food for people, commercial farmers will produce insect products like feed for chickens, farmed fish, and even cats and dogs. Industries already use insects in medicines to color lipstick and to flavor alcohol. And the production cycle starts over with the next generation of insects feeding on organic waste. In addition to all these benefits, insects emit fewer greenhouse gases and require less land to produce than livestock. But don't be too quick to turn up your nose. In Uganda, grasshoppers are a delicacy. A pound costs 40% more than a pound of beef. After all, 2 billion people are already digging in.

- INSECTOS COMESTIBLES

- [Presentador] A medida que la demanda mundial de carne aumenta, los insectos, sí, los insectos, podrían ser una buena alternativa. Más de una cuarta parte de la población mundial ya los consume. Los escarabajos son los insectos más consumidos, pero se han catalogado más de 2000 especies comestibles. Y si logras superar el factor "¡qué asco!", aquí te explicamos por qué son una opción inteligente. Los insectos son una fuente de alimento saludable con alto contenido de proteínas y grasas. Los grillos, por ejemplo, tienen un porcentaje similar al de la mayoría de productos cárnicos. Al ser de sangre fría, los insectos y los peces necesitan, kilo por kilo, menos alimento para crecer que las aves y los mamíferos. De hecho, los grillos son 12 veces más eficientes que el ganado. Esto permitiría que los insectos ayuden a cubrir la demanda de proteína con un impacto ambiental mínimo. La mayoría de insectos cultivados actualmente se usan como alimento animal, pero ya se está trabajando en su producción comercial para consumo humano. El principal reto es reducir los costos de producción y hacerlos más eficientes, y ya se están desarrollando sistemas industriales para lograrlo. Además de proveer alimento para las personas, los criadores comerciales producirán insectos para alimentar gallinas, peces de cultivo e incluso gatos y perros. Las industrias ya usan insectos en medicamentos, para dar color a los labiales y sabor a algunos licores. Y el ciclo de producción vuelve a empezar con la siguiente generación de insectos alimentándose de residuos orgánicos. Además de todos estos beneficios, los insectos emiten menos gases de efecto invernadero y requieren menos tierra para su producción que el ganado. Pero no pongas cara de asco tan rápido. En Uganda, los saltamontes son un manjar. Una libra cuesta 40 % más que una libra de carne de res. Después de todo, ya hay 2 mil millones de personas que los disfrutan.
