Wasteful Food Packaging - The Most Wasteful Packaging For Food
I had to share. What has the world come to that children don't know what fruits and vegetables are?
We lose beautiful creatures like this so quickly and they can never be replaced. What is it going to take?

For the 40th anniversary of Earth Day in 2010, the world is in greater peril than ever, but there is also unprecedented opportunity to build a new future. Earth Day has the power to bring about historic advances in climate policy, renewable energy and green jobs and catalyze millions who make personal commitments to sustainability - A Billion Acts of Green™ – mobilizing the power of people to create change by taking small steps in our homes, our schools and our businesses that add up to an enormous collective action.
Earth Day 40 is a pivotal opportunity for people, corporations, and governments to join together to create a global green economy. Our coordinated efforts now will be recognized by future generations as a turning point.

A NEW solar cell that imitates Mother Nature’s way of converting sunlight to energy is making its debut in a variety of consumer products.

G24iMimicking how leaves use chlorophyll to begin photosynthesis, new solar panels on sports bags can be used to recharge music players and cellphones.
The technology uses a photosensitive dye to start its energy production, much the way leaves use chlorophyll to begin photosynthesis.
The dye-sensitized cells will be used to provide power for devices ranging from e-book readers to cellphones — and will take some interesting forms. For e-book readers, for example, the cells may be found in thin, flexible panels stitched into the reader’s cover. But such panels will also be housed in new lines of backpacks and sports bags, where they can recharge devices like cellphones and music players.
The technology, long in development, will work best in full, direct sunshine, said Dr. Michael Grätzel, a chemist and professor at the École Polytechnique Fédérale de Lausanne in Switzerland. But the cells will also make good use of dappled and ambient light, including the indoor light of fluorescent bulbs, he said.
Most photovoltaic cells are based on silicon or related inorganic materials, not dyes. Dr. Grätzel and an American colleague, Brian O’Regan, first reported on the new type of cell in the journal Nature in 1991, and Dr. Grätzel said that he and other colleagues had been working since then to refine the technology. Now G24 Innovations, a company in Campbell, Calif., that has licensed the technology, is using it to make solar panels at its plant in Cardiff, Wales, said John Hartnett, G24’s chief executive.
Some of the panels will be placed on covers designed as an accessory for Sony e-book readers, said Tobi Doeringer, the director of global sales at Mascotte Industrial Associates, a Hong Kong company that makes bags to carry cameras, phones, sports equipment, electronic games and other products.
Mr. Doeringer said the covers, costing about $99, would be available by March. The cover supplies the power via a plug in a cradle along its spine.
The panels will also be installed on tennis bags, backpacks and messenger bags that have battery chargers within, as well as on bicycle, golf, shopping and beach bags. Prices of the bags will typically range from $149 to $249, he said, depending on the materials and size of the bag. Owners can plug their phones and music players into the bag for recharging, using a USB cord.
Some bags are already available, including messenger bags from Tonino Lamborghini, a brand licensed and distributed by Mascotte. Others will be on the market by the end of the first quarter, he said.
The solar panels have 11 cells each, said Kevin Tabor, director of science and research at G24. Wiring goes from the panel to a battery pack in the bag, he said. It takes about six to eight sunny hours outside for the panel to fuel the recharger, he said, but longer indoors.
The performance of the dye-sensitized cells has improved steadily in the laboratory, Dr. Grätzel said. “Our dyes and electrolytes have changed,” he said, and the cells have become more efficient at converting sunlight to electricity.
Within the solar cell, the dye is painted in a thin layer on a porous titanium dioxide scaffold to collect light and, in a series of steps, create power.
AN Australian company, Dyesol, supplies materials to G24 Innovations and other companies developing dye solar cell technology, said Marc Thomas, the chief executive of Dyesol’s North American operations in Sacramento. Dyesol provides the dye, titanium pastes and the electrolytes for the thin-film technology, he said. Titanium dioxide is a common, inexpensive ingredient that is used, for example, to whiten toothpaste.
Mr. Thomas noted that Dyesol customers were planning to use the technology to prolong battery life in devices like wireless sensors and keyboards.
The cells draw on many surprising sources of light, he said, including some that offer the barest trickle. “We’ve even had a case where we have generated voltage from moonlight,” he said.

I will definitely have to research more into this.
