soto: let's get to that. if there is reduction in leasing, is it a supply, demand or regulatory issue? mr. uillace: i would say it's primarily a demand issue. so -- rep. soto: americans in the world are reducing their demand on oil, and that is leading to less desire for leases? dr. squillace: yes, but i want to emphasize one important point about the regulatory issue. there has been a lot of discussion today about the regulations and the ways in which government regulation might limit development. i tried to point out in my original testimony, the problem here is that we're dealing with public lands and it's necessary, it's not just that it's legally required, it's necessary that we focus on what the consequences are of full field development of oil and gas resources on our public lands. that kind of development can be devastating, and it's happened a lot in our private lands, but i think it's much more problematic when it happens on public lands , so there is a regulatory component, but it's a necessary component that is designed to make sure that we're protecting all of the resources tha
