"Energies and the fate of planet Earth" series: biomass!

Duration: 0:11:24.181927

In an interview, Marco Bravo discussed the importance of biomass energy in Brazil as part of a broader series on sustainable energy sources. He explained that Brazil has the potential to become a global leader in biomass energy production, particularly from sugarcane byproducts like bagasse. Biomass, derived from plant materials, serves as a renewable energy source and can be converted into energy through combustion. Brazil produces both ethanol from sugarcane juice and additional ethanol from bagasse, which can also be used to generate energy. Bravo highlighted the economic advantages of converting bagasse into bioplastics, noting that while burning a ton of bagasse costs $20, producing bioplastics from it can range from $1,000 to $4,000, reflecting a growing market. He emphasized that biomass energy plays a significant role in Brazil's energy matrix, contributing around 9% of the country's energy. Despite being surpassed by China and India, Brazil has a storied history with ethanol, dating back to the 1970s, and now possesses advanced technology in sustainable energy production. The conversation also touched on climate change, with Bravo stressing the urgent need for carbon reduction strategies to mitigate extreme heat events, which are increasingly prevalent due to both seasonal changes and human-induced climate factors. He advocated for cleaner technologies and sustainable fuel sources, such as ethanol, wind, solar energy, and green hydrogen, as essential steps toward addressing the challenges posed by climate change.

Voices. EP#15. Ethnicity and Activities - Walê Fulni-ô Part II - Jacildo Ribeiro

Duration: 0:05:45.286530

Hello, my name is Jacildo Ribeiro de Araújo, and I am part of the Fulni-ô ethnicity, also known as Carijó. This ethnic group has formed from various subgroups that were previously recognized as Carijó, but now identify as Fulni-ô. Our cultural activities focus on promoting and preserving our culture, as well as participating in local celebrations and events. I view the Indigenous Peoples' Day on April 19 as a moment of harmony and reflection among indigenous peoples, highlighting our continued existence and resilience since 1500. This day allows us to share our reality and be heard by non-indigenous people, fostering understanding and appreciation through festivities. However, I am concerned about the recent decline in public policies for indigenous people. The National Indian Foundation (FUNAI), which was created to defend our rights, has lost much of its power and has seen a reduction in its role regarding education, health, and employment opportunities. Indigenous people still face significant prejudice, making it difficult for us to find work or access higher education due to limited opportunities and available spots. I believe that more initiatives and support are needed for indigenous populations in Brazil, as we are among the original inhabitants of this land. This testimony is part of the repository of indigenous cultures and was recorded for the educational radio station UFOP in 2018.
