Setting aside any federal or state laws, do you think companies should

be required to consider the environmental impact of their business on the physical environment wherever they do business, ie. in US or Internationally? Why or why not? Also, do you think the current federal laws do enough to protect our physical environment from businesses and their practices? Why or why not? What should be improved, eliminated, changed, etc. Remember to do some research on these issues to determine your stance on this issue.
