Deforestation contributes significantly to rising temperatures, causing health risks like heat deaths. A study indicates that between 2001 and 2020, substantial tree loss in tropical regions impacted millions globally. Researchers found that heat-related deaths occur mainly in Africa, Southeast Asia, and Latin America, highlighting an urgent public health crisis, especially for indigenous communities.

In Latin America, deforestation has led to the highest temperature increases, making local conditions very dangerous for some populations. Agriculture, mining, and logging all contribute to this issue, causing a rise in local temperatures due to the removal of trees that naturally cool the area.

While fewer people live in deforested areas in Latin America compared to Africa and Asia, the vulnerable communities there face significant health risks from extreme heat. Experts emphasize the need for renewed policies to combat deforestation, protect the environment, and promote public health through better land-use strategies.

Genes linked to chronic kidney disease

Researchers led by Alejandro Chade at the University of Missouri studied genes involved in chronic kidney disease using animal models. They found genes linked to kidney damage; silencing one gene lowered fibrosis. The team will map and test gene activity.
