Brazil has hosted several events to discuss poverty eradication and sustainable development from the perspective of different social groups, occasionally antagonistic, such as Rio +20, the People's Summit and the World Social Forum. Due to the fact that nature does not recognize national borders, scientists see both issues from a global perspective.
Brazil imeandaa matukio kadhaa ya kujadili kuondolewa kwa umaskini na maendeleo endelevu kutokana na mtazamo wa makundi mbalimbali ya kijamii, mara kwa mara upinzani, kama vile Rio +20, Mkutano wa Watu na Mkutano wa Jamii wa Ulimwengu. Kwa sababu ya uhakika wa kwamba asili haing'amui mipaka ya kitaifa, wanasayansi wanaona masuala yote mawili kwa mtazamo wa kidunia.
