Answer:
D. to establish policy to preserve natural resources for future generations
Explanation:
In 1908, Roosevelt organized the Conference of Governors in the White House, focusing on natural resources and their efficient use. His speech marked the epoch and consecrated conservation as a political theme: "Conservation as a national duty". In addition, Roosevelt communicated intensely with other heads of state and sought to influence them to conserve their natural patrimony.
The politicization of the issue of the conservation of natural resources owes much to Roosevelt, who effectively placed the issue on the American political agenda, and who later made important contributions to it in other countries.
