Escassez de Água

Summary

The video highlights the global water crisis, emphasizing that while over 70% of the Earth’s surface is covered by water, only a small fraction is suitable for consumption. It underscores the stark reality that 2.2 billion people lack access to drinking water, with Brazil holding a significant portion of the world’s fresh water yet facing internal distribution challenges. The crisis is exacerbated by urbanization, population growth, and social inequality, impacting marginalized groups the hardest. Environmental racism further amplifies the issue, as vulnerable populations bear the brunt of water scarcity and pollution. Industrial and agricultural expansion worsens the environmental degradation, threatening basic human rights.
