what are three big dilemmas for sustainability?

1. Climate Change: This is one of the biggest potential dilemmas for sustainability. Climate change is a global environmental threat that is accelerating, leading to more frequent and intense extreme weather events, climate-related displacement and migration, and the danger of food and water insecurity.

2. Biodiversity Loss: The rapid and unprecedented loss of species, habitats, and ecosystems across the world is eroding our natural infrastructure and degrading key environment services that we all rely on. As a result, biodiversity loss impacts human and wildlife health, disrupts essential ecosystem functions, and threatens long-term sustainability.

3. Deforestation: As forests are cut down, cleared away, and transformed for agricultural expansion and commercial use, large amounts of carbon are released into the atmosphere and habitats are destroyed, impacting biodiversity and the ability of these ecosystems to store carbon. Deforestation impacts livelihoods, food security, and water systems, exacerbating the risks of natural disasters and furthering global inequalities.

1. as we become more prosperous our taste for consumption has grown which is a major source of environmental degradation 2.the conundrum- we invest efficiency returns into additional consumption 3- behavioral change is more important than technological change -overall reductions in consumption are more important than efficiency -there are significant social and economic barriers to reducing consumption
