This one may offend you more sensitive types as “ironic” or not green at all. But the fact is, the world needs bulldozers. Lots of them. But until now, anyone seeking a hybrid bulldozer was out of luck. But Caterpillar, the prolific maker of construction equipment has announced that for 2010 they will be selling the D7E, a diesel-electric bulldozer.
In the aftermath of another extended rainy season, Liberia has experienced its worst caterpillar plague in three decades. Tens of millions of the black-haired creatures have swarmed farms, devastated crops and contaminated several major waterways with their feces. The lingering rainy seasons, which might be an indication of global warming, are the likely culprit for the creepy invasion.
Liberian agriculturalists have called for extensive aerial spraying to combat the rapacious larvae, since the caterpillars have managed to bypass more minimal, local attempts to divert the hordes. But UN Food and Agriculture Organization (FAO) officials are concerned that these drastic measures could sacrifice long term recovery for a short term fix. The pesticides could contaminate an already precarious food and water supply, which would escalate environmental concerns in the region for years to come.
