by Fred Smith 2004
Nature cannot protect itself. Trees cannot have standing as legal actors, but behind every tree can stand an owner who, by protecting his property, protects it for all.

New environmentalism
by Lynn Scarlett 1997
This paper presents a commonsense approach to public policy toward the environment. Instead of focusing on what decisions should be made, it focuses on how they should be made and by whom. Specifically, the paper proposes a methodology for making decisions based on a covenant between citizens and their government. The covenant is an agreement about principles that will be used in making public policy decisions and about filters that will be relied on to determine the appropriate context for those decisions.

Is free market environmentalism "mainstream"?
by Terry L. Anderson/Jane S. Shaw 2003
Is free market environmentalism part of "mainstream" environmental economics, or is it just "one school"? The answer is that it may have been just "one school" when it was introduced in the late 1970s, but it has become part of the mainstream.

New environmentalism 2004
Nonprofit organizations, businesses, individual citizens, and local governments are playing a crucial role in providing environmental enhancements. Where once environmental policy inherently mistrusted markets and punishment was pursued more vigorously than progress, today this is changing. Private innovation is the wellspring source of progress. We have learned that while environmental enforcement is indeed important, no process should overshadow the ultimate goal of progress toward a clean environment. This is the new environmentalism.
