Document Summary

All of these components are closely linked to environmental quality and the sustainability of ecosystem services: habitat for wild-life, capturing sunlight via photosynthesis, pollination, soil. Assessed in terms of problems of inputs and outputs. As long as sources (inputs natural resources) and sinks (outputs wastes) are used and recycled/ replenished in approximately equal levels we are okay. **the sustainable rate of use for renewable resources can be no greater than the rate of regeneration eg. rate of fishing that is no greater than the rate of fish population growth. **the sustainable rate of use can be no greater than the rate at which a renewable resource can be substituted for it e. g energy from oil is used to develop alternative energy sources. ** the sustainable rate of emission can be no greater than the rate at which the pollutant can be recycled, absorbed or rendered harmless in its sink.
