The book explores the challenges faced by agro-extractivist populations in Pará, focusing on their cultivation and extraction of medicinal and aromatic plants, oils, and resins. Families engage in these practices for personal use or sale, yet they often struggle to connect with the market. Despite the presence of specialized companies acquiring these bioactives, local communities frequently find themselves at a disadvantage in navigating economic relationships. The narrative highlights the intersection of traditional practices and modern market dynamics.

The book explores the challenges of urbanization in Brazil, particularly focusing on the growth of medium-sized cities and its adverse effects on water resources and drainage systems. It highlights how unplanned land occupation disrupts natural drainage, leading to frequent urban flooding. The text discusses the importance of Land Use and Occupancy Laws as management tools to regulate and guide the spatial distribution of socioeconomic activities, aiming to mitigate these environmental impacts.

The book delves into the intricate relationship between air quality and environmental health, highlighting how alterations in atmospheric conditions lead to the degradation of essential natural processes. It explains the detrimental effects on photosynthesis, the nitrogen, oxygen, and carbon cycles, and how these changes contribute to climate variations. The narrative emphasizes the seasonal fluctuations in air quality, particularly worsened during winter months, and explores the interactions between pollution sources and atmospheric conditions that ultimately affect human and animal health.

The book explores the impact of shifting agriculture, particularly slash and burn practices, on the Amazon's primary forests. It highlights the cycle of soil depletion and the need for farmers to constantly clear new land. In contrast, it advocates for agroforestry systems (SAF) as a sustainable alternative, capable of restoring degraded areas and allowing for long-term, fire-free agricultural practices. SAF can support diverse crop production while promoting reforestation and soil recovery, challenging the misconception that such systems threaten primary forests.

The book explores the critical role of urban cleaning and waste management beyond mere aesthetics, emphasizing its importance in public health and environmental preservation. It highlights sanitation as a comprehensive control of environmental factors affecting human well-being, as defined by the World Health Organization. The text critiques various harmful disposal practices in Brazilian cities, such as using raw garbage as fertilizer, polluting water bodies, and improper waste dumping in public spaces, underscoring the need for improved waste management strategies.

The book addresses the global challenges of sewage collection and treatment, highlighting the significant pollution caused by domestic sewage. It discusses the harmful effects of fecal contamination and high concentrations of detergents and oils on public water supplies. The text explores how sanitation involves managing environmental factors that impact human well-being and how domestic effluents vary based on climate, socio-economic conditions, and population habits. Additionally, it details the composition of domestic effluents, including solid waste and dissolved minerals.
