A chance to fix a neighborhood
There is a huge hole in our economic fabric where clean tech should be. And residents of this community can be trained to fill these "green collar" jobs. Instead of all these economic-growth agencies pushing for stadiums or big-box stores where the average wage is $7 an hour, the city could invest in cleaner transportation systems such as barges and rail lines to connect us to the rest of the city. We could take all the waste grease from the food industry that now gets trucked here for disposal and process it instead into biodiesel fuel. Workers will install "green roofs" on commercial buildings, which will provide cooling and generate

The ocean's food chain is at risk
We were one of the first to call attention to the acidification of the oceans. The oceans take up a huge amount of carbon dioxide from the atmosphere every year. A portion of that carbon gets turned into carbonic acid, so that the more carbon dioxide there is in the atmosphere, the more acidic the oceans become. The oceans are now 30 percent more acidic than they were before the Industrial Revolution. It's the most chilling change I've seen in my professional career. If it continues, tiny organisms at the base of the food chain will have their shells dissolve while the animals are still alive. It will

Small changes quickly add up
We are only as healthy as our planet. And, unfortunately, it's obvious that we're not doing a good job in keeping our planet healthy for our children. It's clear to me and to many experts in the field that environmental toxins play a role in some childhood cancers and other illnesses. But people get overwhelmed. They believe the problem is just too big. When people saw "An Inconvenient Truth," they were saying, "How can I save the glaciers? How can I save the polar bears?" All you have to do is make simple changes. Most of us use the same cleaning products our mothers used.

Director of Corporate Responsibility, Intel

Being green is just good business
As the largest chip manufacturer worldwide, Intel has been leading the area of environmental excellence for decades. For us, being green is just part of the way we do business. One thing that plays to our advantage is that our manufacturing process essentially gets refreshed every few years. We can anticipate that, so instead of having to retrofit facilities, we've applied a philosophy of design for environmental health and safety that projects eight to 10 years down the road. With each step we take in successive generations of the chip, we employ different manufacturing recipes every two years. So when we went from the eight-inch wafer to the 12-inch

Everybody can do something
One important lesson I've learned in advocating environmental progress is that the perfect is the enemy of the good. It's not about everyone doing everything. Those days are over. In fact, that's part of what held back the movement. We can't hold people up to a gold standard, because that's unattainable. We're all guilty of being part of this problem. I have a swimming pool that I keep heated for our kids and a house that's got a big carbon footprint. I recognize that and try to do other things, not to justify it but to do the best I can. I can't do everything. But it's about everybody doing something. And if everyone would do something, we
