Economist: Tropicorp, which constantly seeks profitable investment opportunities, has been buying and clearing sections of tropical forest for cattle ranching, although pastures newly created there become useless for grazing after just a few years  The company has not gone into rubber tapping, even though greater profits can be made from rubber tapping, which leaves the forest intact  Thus, some environmentalists argue that <b> Tropicorp's actions do not serve even its own economic interest  </b> However, the initial investment required for a successful rubber-tapping operation is larger than that needed for a cattle ranch; there is a shortage of workers employable in rubber-tapping operations; and taxes are higher on profits from rubber tapping than on profits from cattle ranching
Consequently, <b> the environmentalists' conclusion is probably wrong
The first supports the conclusion of the environmentalists' argument; the second states that conclusion.
