455A.15  Legislative findings.
  The general assembly finds that:
  1.  The citizens of Iowa have built and sustained their society on Iowa’s air, soils, waters, and rich diversity of life. The well-being and future of Iowa depend on these natural resources.
  2.  Many human activities have endangered Iowa’s natural resources. The state of Iowa has lost ninety-nine and nine-tenths percent of its prairies, ninety-eight percent of its wetlands, eighty percent of its woodlands, fifty percent of its topsoils, and more than one hundred species of wildlife since settlement in the early 1800’s. There has been a significant deterioration in the quality of Iowa’s surface waters and groundwaters.
  3.  The long-term effects of Iowa’s natural resource losses are not completely known or understood, but detrimental effects are already apparent. Prevention of further loss is therefore imperative.
  4.  The air, waters, soils, and biota of Iowa are interdependent and form a complex ecosystem. Iowans have the right to inherit this ecosystem in a sustainable condition, without severe or irreparable damage caused by human activities.
