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.

“ The moment before they called my name, I was really nervous because the other finalists’ presentations are really good and I thought they would win, ” Kara Fan, 14, who has won America’ s Top Young Scientist, told Yahoo Finance. “ When they announced my name, I was really surprised actually. ”
To win that claim, Fan’ s nano-particle liquid bandage had to surpass the experiments of hundreds of fifth to eighth graders as well as nine other finalists. Fan started developing her liquid bandage in April 2019 to fight the overuse of antibiotics(抗生素).
According to the CDC, roughly 2 million people every year suffer a bacterial infection in the U. S. and about 23, 000 passed away as a result. If left alone, a UN study reported, drug- resistant diseases or the “ superbug” could lead to 10 million deaths across the globe by 2050. When Fan’ s sprayable bandage dries on a person’ s skin, it creates a thin layer that protects the wounded area while breaking the cell wall and killing the bacteria on the skin. After experimenting with copper nitrate(硝酸铜) to fight bacteria, switching to the silver nitrate ended up being the major catalyst (催化剂) to seeing results for her award-winning project.
“ Thousands of years ago, ancient people would use copper and silver to eat with and they would drink water from like copper bowls to kill bacteria, ” Fan explained. “ I found out that it didn’t work. So I used nano silver. ”
Sir Alexander Fleming’ s discovery of penicillin— a type of antibiotic— is Fan’ s favorite scientific discovery. That said, she doesn’ t think humans should rely too heavily on penicillin.
Following her years at Westview High School, Fan hopes to continue her biology track at Stanford University. Along with the ＄ 25, 000 cash prize she won on October 29, becoming Amer-ica’ s Top Young Scientist may help get the private university’ s attention.
1.How did Kara Fan feel about her winning the prize?
A.Confident. B.Regretful.
C.Proud. D.Unexpected.
2.For what purpose did Fan develop her liquid bandage?
A.To fight overuse of antibiotics. B.To enter a national contest.
C.To reduce deaths from injuries. D.To get into a good university.
3.Which of the following does Fan use to kill bacteria?
A.Copper nitrate. B.Copper.
C.Silver. D.Nano silver.
4.What might be Fan’ s opinion about penicillin？
A.Addictive. B.Valuable.
C.Useless. D.Irreplaceable.
With bushfires continuing to swallow different parts of Australia, a local zoo in New South Wales - the state which is the easiest to catch fire - has hit the headlines with a heartwarming story.
Right in the line of a bushfire, the keepers of Mogo Wildlife Park managed to protect all 200 animals from harm after they received evacuation orders, according to reports.

Last Saturday, my friends and me went to climb the West Mountain. While climb, we enjoyed the sunny weather and a beautiful view. We were very delighted reach the top without much time or effort. Therefore, we found it more difficult to go down, so we went slowly but helped each other when necessary. Though I took care a lot, unfortunately I slip and hurt my leg badly. As the result, I could hardly stand up. One of my friend came to me immediately and carried me on the back till we reached for the foot of the mountain. I was very thankful and felt proudly of having such good friends.
