Counting the number of miles traveled done by a product is a strange way of trying to tell the true situation of the environmental damage due to industry. Most food is transported around the world on container ships that are extremely energy efficient. It should be noticed that a ton of butter transported 25 miles in a truck to a farmers' market doesn't necessarily use less fuel on its journey than a similar product transported hundreds of miles by sea. Besides, the idea of “food miles” ignores the amount of fuel used in the production. It is possible to cut down your food miles by buying tomatoes grown in Britain rather than those grown in Ghana. The difference is that the British ones will have been raised in heated greenhouse and the Ghanaian ones in the open sun.

    What is the idea of “food miles” doesprovide, however, is the chance to cut out Third World countries from First World food markets. The number of miles traveled by our food should, as I see it, be regarded as a sign of the success of the global trade system, not a sign of damage to the environment.

    Nowadays people are putting our water supply in danger, because they use too much water or throw rubbish into the river. You may wonder how paving(铺砌) a road can lead to less usable fresh water. A major part of thewaterweuse every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave，the less water can flow into the ground to become groundwater.

    Human activity is not responsible for all water shortages(短缺). Drier climates are of course more likely to have droughts(干旱) than areas with morerainfall，but in any case, good management can help to make sure there is enough water to meet our basic needs.

    Thinking about the way we use water every day can make a big difference，too. In the United States，a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live，but there's a lot we can do to lower the number.

    You can take steps to save water in your home. To start with，use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher (洗碗机)only when it is full. Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.

    Scientists today are making greater effort to study ocean currents (洋流) . Most do it using satellites and other high-tech equipment. However, ocean expert Curtis Ebbesmeyer does it in a special way -- by studying movements of random floating garbage. A scientist with many years' experience, he started this type of research in the early 1990s when he heard about hundreds of athletic shoes washing up on the shores of the northwest coast of the United States. There were so many shoes that people were setting up swap meets to try and match left and right shoes to sell or wear.

    Ebbesmeyer found out in his researches that the shoes — about 60,000 in total — fell into the ocean in a shipping accident. He phoned the shoe company and asked if they wanted the shoes back. As expected, the company told him that they didn't. Ebbesmeyer realized this could be a great experiment. If he learned when and where the shoes went into the water and tracked where they landed, he could learn a lot about the patterns of ocean currents.

    The Pacific Northwest is one of the world's best areas for beachcombing(海滩搜寻) because winds and currents join here, and as a result, there is a group of serious beachcombers in the area. Ebbesmeyer got to know a lot of them and asked for their help in collecting information about where the shoes landed. In a year he collected reliable information on 1, 600 shoes. With this data, he and a colleague were able to test and improve a computer program designed to model ocean currents, and publish the findings of their study.

    As the result of his work, Ebbesmeyer has become known as the scientist to call with questions about any unusual objects found floating in the ocean. He has even started an association of beachcombers and ocean experts, with 500 subscribers from West Africa to New Zealand. They have recorded all lost objects ranging from potatoes to golf gloves.

    It was a Saturday morning, a day I believed would end in victory. For weeks, I had been preparing for the match at the county fairgrounds, sponsored(赞助) by our local riding club. My horse, Tonka, and I could run faster than any kid in the county, and I hoped to bring home a blue ribbon.

    My mother usually drove me to the riding events, but on this day, my father planned to drop us off at the fairgrounds with the horse trailer(马车) .

    Although we never discussed it, my father's struggle with alcoholism had become the silent center of our family life. My mother was paralyzed with fear and indecision. Her salary as a part-time nurse couldn't possibly support four children. No one talked about alcoholism in those days, and it was my family secret.

    We climbed on the trailer and my father pulled out of our driveway and headed toward the fairgrounds, picking up speed once we hit the main road. It wasn't until we felt a big bump that I realized the trailer was out of control. The dream of my riding winner disappeared. Tonka lay on the floor, completely still. No words were possible. I knew he was dead.

    Suddenly a man appeared. "Are you all right?" he asked. "Yes." I answered, although I knew that nothing was all right. "Sit here on the grass," he said. He bent down to look into the trailer. Tonka remained still. He touched Tonka and then turned to face me. "He is going to be OK. He has just been knocked unconscious." He rubbed Tonka's cheeks and gently pulling his ears. Tonka rose to his feet.

    Our father was talking to a police officer. He was upset and in pain and took little notice of me. I looked back; the man was gone.

    I never forgot him. He gave me strength and a sense of hope in a dark and frightening moment.

    I was attending a party one night given in Sir Ross's honor; and during the dinner, the man sitting next to me told a humorous story based on the quotation(引语): “There's a divinity that shapes our ends, rough-hew them how we will.”

    The storyteller mentioned that the quotation was from the Bible. He was wrong. I knew that, and I knew it positively. There couldn't be the slightest doubt about it. And so, to get a feeling of importance and display my superiority, I appointed myself as an unwelcome committee of one to correct him. He stuck to his guns. “What? From Shakespeare? Impossible! Absurd! That quotation was from the Bible.” And he knew it.

    The storyteller was sitting on my right; and Frank Gammond, an old friend of mine, was seated on my left. Mr. Gammond had devoted years to the study of Shakespeare. So the storyteller and I agreed to submit the question to Mr. Gammond. Mr. Gammond listened, kicked me under the table, and then said: “Dale, you are wrong. The gentleman is right. It is from the Bible.”

    On our way home that night, I said to Mr. Gammond: “Frank, you knew that quotation was from Shakespeare.” “Yes, of course,” he replied, “Hamlet, Act Five, Scene Two. But we were guests at a happy time, my dear Dale. Why prove to a man he is wrong? Is that going to make him like you? Why not let him save his face? He didn't ask for your advice. He didn't want it. Why argue with him? Always avoid your sharp angle.” The man who said that taught me a lesson I'll never forget. I not only had made the storyteller uncomfortable, but also had put my friend in an embarrassing situation. How much better it would have been had I not become argumentative.

    Nine times out of ten, an argument ends with each of the contestants more firmly convinced than ever that he is absolutely right. You can't win an argument. You can't because if you lose it, you lose it; and if you win it, you lose it.

    Someone sent me an email urging me to acquire a lot more resources, suggesting that I could do so much more good if I had an 8 or 9figure net income (净收入) instead of 6 like I've been doing for years. He claimed to have acquired a great deal of wealth himself and found it highly beneficial to fueling his path with a heart.

As I consider his suggestion, I find myself not having much clarity (清晰的思维) as to what I'd do with 1 million or 10 million more money flowing through my life. I put so much attention on creativity, fulfillment, exploration, relationships, etc. that I find it difficult to intelligently imagine how more financial resources could provide extra fuel for that, except in small ways or in ways that aren't particularly meaningful to me.

Lately I've been considering what it would be like to deliberately reduce my income for a while and see if I could live on much less, just for the experience. What if I capped my net personal income at $10,000 per year, for instance? That isn't such a big deal to me, though, since I already went through a period of low income like that during the 1990s, and I learned that I could still do what I love regardless of income.

I've never worked in a business environment — the only job I've ever had was working for $ 6/hour in a video game store while I was in college. So I've never seen how larger operations allocate resources. That's probably why I haven't pushed myself to acquire more. As I mentioned in my book Money and Your Path With a Heart, my main financial goal in life was to make money irrelevant in my life.

    I'm not interested in building an empire. What interests me is exploring personal growth and sharing what I learn along the way. In some ways I feel that acquiring and allocating more resources could become a big distraction. I'm already doing what I want to be doing, so why risk distracting myself to acquire more resources, especially when I lack the idea about how I should treat such resources? I like having freedom and flexibility, and I don't really see how more resources would meaningfully improve that.
