Human Activities Disrupt the Web of Life Through Biodiversity Loss and Technology

The efforts to increase society's environmental sustainability focus on four major challenges that need to be addressed: climate change, natural resource dissipation, environmental pollution, and biodiversity loss. Impacts on climate change are relatively straightforward to characterize through CO2 emissions. We even have ways to convert emissions of other greenhouse gases like methane and laughing gas, into CO2 equivalents, so we can calculate the overall impact on the climate in tons of CO2.
