There are billions of people on this planet, and many of us love to eat meat. Can the demand be filled in a sustainable(可持续的) and affordable way? A bunch of businessmen are not only optimistic but are working to make this happen sooner than you may think.
The environmental effects caused by meat consumption (食用)—waste, animal treatment, health problems and even the greenhouse gas effects that are potentially caused by methane gas produced by cows—have given rise to a number of startups(新兴公司)looking to develop meats in different ways.
For example, San Francisco-based Memphis Meats is developing cell-based meats in its labs without requiring any animals. Israel’s Future Meat Technologies is doing the same by producing fat and muscle cells that are being tested by chefs in Jerusalem. All of these companies use special processes to harvest cells from animals and grow them in a lab.
But don’t worry if you’re not a meat lover. Startups such as Jet Eat, which is also based in Israel, are working on food products grown in labs that are plant-based and replicate (复制) meats using natural elements while still keeping flavor, consistency and the “overall sensory experience”, according to a report on NoCamels. Jet Eat, which was founded in early 2018, aims to 3D-print their lab-grown products by 2020.
As you can imagine, there are plenty of barriers facing the industry. Educating the public is a big one. Another controversial issue is the labeling of the products. Recently both the USDA and the Food and Drug Administration(FDA) announced that they will begin jointly controlling the new “cell-based meat” category.
Many of us have concerns about the challenges facing future generations as our global population increases and the earth’s natural resources decreases. The good news is that there are plenty of businessmen around the world—like those producing lab-grown meats—who are working to solve some of these problems and make a little money in the process. Nothing wrong with that.

A 2018 report found that food waste would increase by a third to 2. 1billion tons by 2030. Beyond the cost of the waste itself，thrown-away food generates a gas that contributes to climate change.
Home delivery meal kits(盒)can reduce food waste by more than two-thirds，but suppliers need to switch to reusable packaging to make them environmentally friendly.
Tailor-made meal kits cut waste by providing people with precise amounts of fresh ingredients(烹饪原料)for chosen recipes，meaning leftovers are minimized. But while the delivery services score well on reducing food waste，buying the same food ingredients from the supermarket almost always saves energy overall simply because meal kits use so much single-use packaging. The good news is that if people have meals that are tailored for consumption，they won’t overbuy and have less food waste. They fine-tune the amount of food to what they will actually eat.
Meal kits can reduce transport emissions(排放)if people go to the supermarket less frequently. If people only go and buy such goods as soap and toilet paper，they may only have to visit once every couple of months. A delivery truck can carry meals for a lot of people in the neighborhood. So dozens of car trips might be replaced with one truck trip.
However，study found that even if delivery meal kits reduced food waste to zero，they would still use up more energy overall than buying the same food from the supermarket unless the energy used for the meal kit packaging was cut by a fifth. The packaging is a killer if it’s single-use and thrown away，which can make all the environmental benefits lost. But if the packaging can be reused，if it’s glass bottles，like in the old days，we can get some benefits.

4.What’s the author’s attitude to meal kits?
A.Supportive. B.Unfavorable.

When a tornado touched down in a small town nearby, many families were left completely ruined. One Sunday, a particular picture especially touched me. A young woman stood in front of an entirely ruined home. A young boy, seven or eight years old, stood at her side, eyes downcast. Clutching(紧握) at her skirt was a tiny girl who stared into the camera, eyes wide with confusion and fear. The article that went with the picture gave the clothing sizes of each family member. With growing interest, I noticed that their sizes closely matched ours. This would be a good opportunity to teach my children to help those less fortunate than themselves. I taped the picture of the young family to our refrigerator, explaining their difficulty to my seven-year-old twins, Brad and Brett, and to three-year-old Meghan.
“These poor people now have nothing,” I said. “We’ll share what we have with them.”
I brought three large boxes and placed them on the living room floor, encouraging the boys to go through their toys and donate some of their less favorite things. Meghan watched seriously, as the boys and I filled one of the boxes with canned goods and foods that they no longer needed.
Meghan walked up with Lucy, her much -loved doll, hugged tightly to her chest. She stopped in front of the box, gave her doll a final kiss, then laid her gently on top of the other toys.
“Oh, Honey,” I said. “You don’t have to give Lucy. You love her so much.”
Meghan nodded seriously, “Lucy makes me happy, Mommy. Maybe she’ll make that other little girl happy, too.”
Para. 1
The boys had watched, open-mouthed, when their sister placed her favorite doll in the box.
