    In order to change the way Americans think about their trash footprint, Rob Greenfield is going to live like the average American for one month. He'll eat, shop, and consume just like the average American who14.5 pounds of trash per day. He has to2every piece of trash he creates. That's nearly 140 pounds3the end of the month(almost his body weight)! Every coffee cup, plastic bag, pizza box, every single piece of trash be creates will be on his4, everywhere he goes.

    The idea behind Bob's “TrashMe” project is to show people the5effects of trash. Most people6think about how much waste they are producing every month. They just7their garbage bags, put them in the bin and8someone to pick them up. But what if they came face to face with a walking, talking9of overconsumption? That might get them thinking about the world's10trash problem and maybe even get them to11the amount of trash they generate.

    To make himself12to a wider audience, Greenfield has13a nonprofit film studio LivingOne to create a six-episode TrashMe web-series. He promised to deliver “a visual of14that Americans will never forget.”

    Rob's15adventure began on September 19th, and will end on October 19th. Three days in, he has already put on about 8 pounds, just a little bit16the trash that the average American produces in that time. But 30 days later, he will have put on over 130 pounds of trash. If you're wondering17on Earth he's going to carry all that garbage around, you should know that he will be wearing a custom-made trash suit to18around 135 pounds of trash. Still, that's19his own body weight, so it's not going to be20to move around.

    One a February day during an unusually mild winter, I found myself missing the snowy beauty. I enjoyed the feeling that comes from watching snow fall gently from heaven while I'm cosy inside with a good fire burning in the stove. But there were more serious concerns, like the lack of rainfall making our woods more accessible to summer forest fires. Local ski fields and hotels, all dependent on a snowy season, felt sorry for the vacant lifts, empty restaurants and unused snowmobiles.

    Then I happened to see three little robins （知更鸟） fly into our yard. What were they doing here? West of us, in the Willamette Valley, wild flowers burst this time of year. But here in central Oregon, even if a groundhog （ 土拨鼠） had wanted to appear, it couldn't have broken through the frozen earth. And yet, these robins had arrived.

    Their presence brought me a flow of happiness. It felt like a celebration as I dug into my bag of birdseed and spread a handful on the ground. Above me, the deep blue sky was cloudless, perfectly quiet but for some smoke from a neighbor's chimney. The lively cold made the air fresh and clean.

    My robins jumped lightly toward the seed. My soul jumped with them, feeling equally carefree. Caught up in the moment of spring fever, I checked our snowless flower beds. To my delight, I spotted a green branch sticking out through the brown soil.

    Despite the cold, I wasn't ready to go back inside. Just a short meeting with those robins had renewed my spirit. The next day I would return to my outdoor work with a cheerful heart and a hopeful eye for these signs of spring.

    What Theresa Loe is doing proves that a large farm isn't a prerequisite for a modern grow-your-own lifestyle. On a mere 1/10 of an acre in Los Angeles, Loe and her family grow, can(装罐)and preserve much of the food they consume.

    Loe is a master food preserver, gardener and canning expert. She also operates a website, where she shares her tips and recipes, with the goal of demonstrating that everyone has the ability to control what's on their plate.

Loe initially went to school to become an engineer, but she quickly learned that her enthusiasm was mainly about growing and preparing her own food. “I got into cooking my own food and started growing my own herbs (香草) and foods for that fresh flavor,” she said. Engineer by day, Loe learned cooking at night school. She ultimately purchased a small piece of land with her husband and began growing their own foods.

    “I teach people how to live farm-fresh without a farm,” Loe said. Through her website Loe emphasizes that “anybody can do this anywhere.” Got an apartment with a balcony （阳台）? Plant some herbs. A window? Perfect spot for growing. Start with herbs, she recommends, because “they're very forgiving.” Just a little of the herbs “can take your regular cooking to a whole new level,” she added. “I think it's a great place to start.” “Then? Try growing something from a seed, she said, like a tomato or some tea.”

    Canning is a natural extension of the planting she does. With every planted food. Loe noted, there's a moment when it's bursting with its absolute peak flavor. “I try and keep it in a time capsule in a canning jar,” Loe said. “Canning for me is about knowing what's in your food, knowing where it comes from.”

    In addition to being more in touch with the food she's eating, another joy comes from passing this knowledge and this desire for good food to her children: “Influencing them and telling them your opinion on not only being careful what we eat but understanding the bigger picture,” she said, “that if we don't take care of the earth, no one will.”
