The PERFECT FIX

摘要

For almost every environmental ill, scientists are working on a technological solution—or three. Some involve simple changes in the products we choose or in the way we use technology in our homes, offices, and industries. Others require replacing entire systems with the latest wizardry. The most comprehensive solutions often combine low-tech smarts and high-tech innovation. No designer of a cutting-edge office building, for example, would rely on on-site biomass energy generation without exploiting the absolutely free lighting and energy benefits of southern exposure. Here's a sample of responses—ranging from simple to sophisticated—to environmental problems we face every day, along with examples of technology we really could do without.
