Por Gerardo Pedra En la entrada pasada nos referimos a la sequía que vivimos en México de marzo de 2022 a octubre de 2025. Parece increíble que justo cuando el gobierno se había propuesto ganar la “soberanía alimentaria”, sin ningún plan real, pero con muchas ganas, el mundo decidió irse en sentido contrario. Es como…
Es algo que no se comenta mucho, pero el país vivió un periodo de sequía bastante severo entre marzo de 2022 y octubre de 2025. Según los datos de Conagua, el momento más severo fue en 2023, cuando realmente llovió muy por debajo del promedio histórico. Las cosas mejoraron mucho el año pasado, incluso arriba…
Estamos en las rondas finales del torneo internacional de futbol cuyo nombre dicen que no podemos repetir. No vayan a pensar que queremos ganar dinero con este humilde blog y nos cobren regalías. Esto de la propiedad intelectual es un asunto serio a nivel Mundial. Lo que es cierto es que tardó mucho en prender el…
The ongoing football tournament is expected to generate 34,000 additional tons of waste in Mexico, equivalent to three days of waste in CDMX. While manageable, it highlights the need for improved recycling practices. Both private gatherings and public venues should implement waste separation to promote recycling during events, particularly in stadiums.
The term "pepenador," referring to informal waste pickers in Mexico, is gaining recognition for its positive roots. Despite working in marginalized conditions, they play a vital role in recycling and waste management, impacting the economy and environment significantly. Formalizing their work and incorporating them into waste policies could enhance both their lives and recycling efficiency.
The World Cup countdown has begun, raising environmental concerns due to increased waste and energy consumption from fans. Implementing circular economy practices, such as reducing, reusing, and recycling, can mitigate this impact. Improved waste management, responsible consumption, and shared mobility during the event can help promote sustainability and leave a lasting positive legacy.
Expanded polystyrene, or unicel, is being transformed into high-value electronic materials via a process called upcycling. Researchers from the University of Delaware developed a method to convert unicel into a conductive polymer, demonstrating its potential in solar panels and biomedical sensors. This innovation promotes sustainability and reduces waste while enhancing economic possibilities.
Todo lo que podemos perder cuando se habla de prohibir el unicel en empaques no es menor: eficiencia logística, seguridad alimentaria, accesibilidad económica y, paradójicamente, avances en sostenibilidad. En el debate público, el poliestireno expandido (EPS), conocido comúnmente como unicel, suele aparecer reducido a una etiqueta simplista de “plástico de un solo uso”. Sin embargo,…
The text discusses the implications of banning materials like polystyrene in the context of circular economy and recycling. It emphasizes that prohibitions stifle innovation and the development of recycling technologies, while effective regulations can foster advancements. The focus should be on creating infrastructure and market demand for recyclable materials rather than outright bans.
On International Women's Day, it's vital to acknowledge the intertwining struggles for social justice and environmental protection. Six women—Rachel Carson, Wangari Maathai, Jane Goodall, Gro Harlem Brundtland, Berta Cáceres, and Julia Carabias—have profoundly transformed our relationship with nature through their leadership, activism, and contributions, inspiring ongoing efforts for a sustainable future.
