Water the elixir of life. The problem is too much of it is chaos. Too little of it is the same.2015 the monsoon had failed. 2016 the city of Burggawi had a water scarcity which was unprecedented. That's when a few people got together and brought out that thing that's taught to everybody in school.When you have more trees, you have more rain. Very childish a thought. But then I guess nothing beats the truth of the innocence of a child who believes that the world can change.And so we believed and we set foot ...

A lesson in resilience from ants | Alan Andersen | TEDxCharles Darwin University
TEDx Talks· 2025-08-26 16:50
Biodiversity and Evolutionary History - Ant communities' characteristics are shaped by their evolutionary past, similar to human cultures [1] - Ants constitute one-fourth of the total weight of all land creatures, surpassing the combined weight of wild birds and mammals [2] - Australian tropical savannas boast the highest ant diversity, exceeding even the Amazon rainforest when considering undescribed species [6][7] - The ant fauna of Australian savannas is primarily derived from arid environments, contrasting with Brazilian savannas, which are forest-derived [8][9] Functional Differences and Adaptations - Australian savannas exhibit a high abundance and diversity of harvester ants (seed-eating ants), while Brazilian savannas have only one species due to their rainforest association [11][12] - Australian savannas possess a diverse genus of highly thermophilic ants ( *Maleopherus* ), capable of foraging at temperatures up to 50°C, whereas Brazilian savannas lack similarly adapted species [13][14] Climate Resilience and Implications - Australian savanna ant diversity remains stable across a rainfall gradient from 1,500 mm to 500 mm per year, unlike the rainfall-sensitive forest-derived ant fauna of Brazilian savannas [15][16] - Projected declines in rainfall due to climate change are unlikely to significantly impact Australian savanna ants but could negatively affect ant diversity in Brazilian savannas [17] Lessons for Humanity - The resilience of Australian savanna ants offers a lesson for humanity in building a resilient future in the face of climate change [18][20] - Preparing for climate change involves adapting to increasingly arid conditions, rising sea levels, and increased risks of floods and fires [19][20]
