Urban Air and Water Pollution in São Paulo and Rio de Janeiro.

As two of Brazil’s largest and most iconic urban centers, São Paulo (SP) and Rio de Janeiro (RJ) have witnessed explosive urban growth in recent decades. While economic and population expansion has fueled prosperity, it has also led to serious environmental consequences, particularly in the form of air and water pollution. These twin challenges threaten the health of millions, degrade natural ecosystems, and impact tourism and quality of life.

Drought Stress and Rainfall Decline in the Amazon: Impacts on Trees, Fires, Biodiversity, and Indigenous Communities.

The Amazon Rainforest, often referred to as the "lungs of the Earth," plays a pivotal role in maintaining global climate stability, biodiversity, and hydrological cycles. Spanning over 5.5 million square kilometers, it is home to an unparalleled variety of plant and animal species, many of which are found nowhere else on Earth. However, this critical ecosystem is facing a mounting threat: decreasing rainfall and increasing drought stress. These climatic changes are not only weakening the Amazon's rich vegetation but also threatening its overall survival.
