Deforestation is another govt made thing these days, as this policy study shows.

In Brazil, government policies are encouraging deforestation of the rain-forest through subsidies and tax credits. The biggest effect is that owners of land reaping the rewards of ownership without paying the costs, and thus are encouraged to act irresponsibly. A study by the World Resources Institute (by no means a group committed to private property) concludes that cattle ranching and settlements by small farmers are the major factors behind deforestation. Both of those activities are heavily subsidized by the government. Author Robert Repetto says that the subsidies encourage the livestock industry to cut down trees to promote pastureland and encourage settlers to turn forests into farmland. (In addition, the government subsidizes the forest products industry.) "By supplying virtually free money, the federal government invited investors to acquire and clear large tracts of forested lands," says Repetto.
“Experience should teach us to be most on our guard to protect liberty when the Government’s purposes are beneficent. Men born to freedom are naturally alert to repel invasion of their liberty by evil-minded rulers. The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well-meaning but without understanding.” — James Madison
