In Brazil's capital, residents of poor neighborhoods on the city's outskirts are suffering from abnormally high temperatures that pose a serious threat to their health. According to observers, one of the key reasons for this situation is the uneven distribution of green spaces throughout the city: while central and more affluent areas have parks and vegetation that mitigate the heat, favelas on the outskirts are virtually devoid of plant life. The absence of trees and parks leads to the formation of so-called "heat islands"—areas of urban development where air temperature is significantly higher than in green areas. This phenomenon is particularly dangerous for vulnerable populations: the elderly, children, and people with chronic illnesses, who find it harder to endure extreme heat. Experts note that the problem of unequal access to green spaces is characteristic not only of Brasília but of numerous cities around the world. Urban greening is considered one of the most effective ways to combat the effects of climate change and reduce temperatures in urbanized zones. Planting trees and creating parks in poor neighborhoods could significantly improve residents' quality of life and reduce health risks associated with overheating. The situation in Brazil's capital serves as a reminder that urban planning and climate justice are closely interconnected: access to natural resources, such as shade and coolness from plants, is increasingly becoming a matter of social inequality.
