Document Summary
According to many commentators, the earth is currently experiencing multiple environmental crises: greenhouse effect, due to human activity, ozone depletion, protects the earth from uv rays (cancer) Human activity has been identified as a primary cause of these environmental crises: at the most basic level, consider population growth: o. Geometric growth common percentage being added (100 +110 billion) Increases the net amount over and over, faster and faster to the point where it becomes unsustainable. Linear growth constant growth (1 billion +1 billion, year after year) Increasing 1. 2%/year o: by 2050 between 8 and 11b people in the world. Environmental issues are political issues, not merely scientific issues: Population growth is not even throughout the world. 86% of global population growth is concentrated in the underdeveloped world: northern tendency to blame the south for over-procreating. By contrast, many developing country governments have noted a correlation between high birth rates and poverty.
