Well, it's that time of year again: the trees are growing, flowers are blooming, high schoolers are preparing for finals - that's right, it's time to celebrate the Earth and all the wonderful things she's done for us over the course of human history.

But as we enter into a new technological era, one has to wonder: what are we doing for her? With the pollution of the Industrial Revolution still flowing freely in our ozone layer, destroying what little there is left of it, and as gas prices soar we begin to look to new, alternative energies to fuel our rapidly-growing population. The human race has never encountered a shortage of fuel like we are seeing now, and the toll that it has taken on Mother Earth will have far-reaching and possibly devestating consequences.

But some people already know this. Mainly in the trucking industry, corporate leaders are stepping up and taking charge, and to celebrate Earth Day this year Mack Trucks is unveiling a dialogue at the Da Vinci Science Center in Allentown, PA to discuss possible new, alternative energies to power their trucks. They're also unveiling a new section of their website to commemorate their shift in focus to new, cleaner energies. But Mack isn't the only one. Navistar recently announced that they've purchased 18 brand-new hybrid long-haul trucks that will operate out of Michigan, Indiana and Ohio. It's not much, but it's progress.

It's good to see the trucking industry getting behind the environmental movement, as most of the pollution that comes from automobiles is spewed from their trucks. It'll be hard to imagine seeing a long-haul truck on the freeway not billowing out its nasty cloud of pollution, but when it comes to the planet, well, let's just say it's a sight that's worth missing.
