The construction of a 12.4 km bridge in Bahia, Brazil, set to be the second largest in the southern hemisphere, raises significant environmental and community concerns. The project, led by a consortium of Chinese companies, aims to improve logistics but threatens local ecosystems, including mangroves and marine life, and traditional fishing communities. Critics argue that the environmental impact study is incomplete and that the project could lead to overpopulation and strain on public services in Ilha de Itaparica. Alternatives such as improving the existing ferry service are suggested as less invasive solutions.

In Rio de Janeiro's Tijuca Forest, surrounded by over 40 favelas lacking sewage systems, the Vale Encantado favela has built a biodigester and rooftop solar power system to address sanitation and energy issues. Community activist Otavio Barros, a member of the Vale Encanto Cooperative, spearheaded the initiative after years of untreated sewage affecting the local environment. With the help of Taboa Engenharia and the Pontifical Catholic University of Rio de Janeiro, the community designed a cost-effective biodigester and artificial wetland. The project, completed in 2022, employs local residents and aims to foster sustainable tourism and income opportunities. The cooperative also installed a solar power system to reduce electricity costs, hoping to inspire other communities facing similar challenges.

In Camocim, Ceará, the fishing village of Praia do Xavier was erased from maps to facilitate the construction of the Central Eólica Praia Formosa wind farm by French company Siif Énergies do Brasil. The wind farm, operational since 2009, has significantly impacted the local community, which previously relied on artisanal fishing and agriculture. The community was not consulted, and their traditional way of life was disrupted by the construction and operation of the wind farm. Legal battles ensued, and the community received some compensation, including new houses. However, issues like food insecurity and land speculation persist. The case highlights the need for inclusive approaches and real consultations with affected communities in renewable energy projects.

Brazil's handling of the pandemic, particularly the procurement of Covid-19 vaccines, has come under scrutiny with allegations of corruption and negligence within the Health Ministry. A parliamentary inquiry commission (CPI) has been investigating the government's response, uncovering evidence of overpricing and irregularities in the contract for the Indian Covaxin vaccine. President Jair Bolsonaro, who campaigned on anti-corruption, is implicated in the scandal, having been informed of the irregularities but failing to act. The scandal has led to protests, weakened Bolsonaro's anti-corruption stance, and may impact his chances in the 2022 elections. Despite this, Bolsonaro still has a strong following on social networks, which could influence his re-election campaign.

Brazilian archaeologists have discovered numerous 2,000-year-old rock carvings in Jalapão State Park, Tocantins, depicting human footprints, celestial bodies, and animals. The findings, made during expeditions between 2022 and 2023, include 16 precolonial archaeological sites with engravings and red paintings, suggesting cultural connections and settlement patterns of ancient communities. The rock art, which may have been created using pointed stones and pigments from iron minerals, provides insights into the spirituality and way of life of Indigenous groups. The work, led by Rômulo Macêdo of IPHAN and commented on by archaeology professor Marcos Zimmermann, indicates technical and thematic similarities with other Brazilian sites, dating the art to around 2,000 years ago. Further analysis and excavations are expected to reveal more about the precolonial populations.

Brazilian archaeologists from the National Institute of Historic and Artistic Heritage discovered numerous 2,000-year-old rock carvings in Jalapão State Park, Tocantins, depicting human footprints, celestial bodies, and animals. The findings, made during expeditions between 2022 and 2023, include 16 precolonial archaeological sites with engravings and red paintings, suggesting cultural connections and settlement patterns of ancient communities. The rock art, which may be older than previously found stone artifacts, provides insights into the Indigenous groups' way of life and spirituality. Further analysis and excavations are expected to yield more information about the precolonial populations.

In Camocim, Brazil, the fishing village of Praia do Xavier was effectively erased from maps to facilitate the construction of the Praia Formosa wind farm by SIIF Énergies do Brasil, a subsidiary of EDF. The wind farm, operational since 2009, has caused significant environmental and social impacts, including restricted access, loss of fishing resources, and noise pollution. Despite legal efforts and compensation measures, the community remains dissatisfied. The case underscores the need for inclusive and consultative approaches in renewable energy projects, especially in sensitive environments.

The article discusses the environmental challenges faced by the Enchanted Valley (Vale Encantado) in Tijuca Forest, Rio de Janeiro, where sewage was improperly disposed of, contaminating a local waterfall. A member of the Vale Encanto Cooperative, Barros, was motivated to seek solutions after a tourist was warned against bathing in the polluted waterfall. The cooperative is part of the Sustainable Favela Network, aiming for socio-environmental resilience. The article also touches on the history of Tijuca Forest, including deforestation for homes, farms, and coffee plantations since the arrival of the Portuguese royal family in 1808, and the subsequent reforestation ordered by Emperor Dom Pedro II in 1861 due to environmental concerns.

The article discusses the decline of the juçara palm in southeastern Brazil's Atlantic Forest due to overharvesting for heart of palm, which was once a significant industry. The extraction of heart of palm, a popular food item, led to the endangerment of the juçara palm, prompting the Brazilian government to impose restrictions and eventually ban the practice. Despite this, illegal harvesting continued. The article highlights the efforts of Cooperfloresta and the Florestal Foundation, which are involved in agroforestry and reforestation programs aimed at reviving the juçara palm population. These programs encourage local farmers to harvest juçara fruits sustainably and participate in a circular economy that supports the repopulation of the species in the Atlantic Forest.

The article by Lobato Felizola discusses the ongoing deforestation and environmental degradation of the Amazon rainforest, highlighting the role of the Brazilian government and private interests in facilitating this destruction. It outlines the history of exploitation in the Amazon, the impact of deforestation on biodiversity and climate, and the legislative maneuvers that legitimize land grabbing and environmental crimes. The article also touches on the international dimension, with U.S. corporations and financial institutions implicated in the trade of commodities linked to deforestation. The journalist criticizes the Brazilian government's lack of commitment to stopping illegal deforestation and the weakening of environmental agencies. The article concludes by emphasizing the dire consequences of the current policies and practices for the future of the Amazon and the planet.
