It was a cold and rainy day. I finished my work late and dragged home. I ________ myself deep into the sofa. I was too ________ to cook anything for myself, so I ordered a pot of chicken upon my phone.

Half an hour later, a delivery worker ________ me that he’d arrived. I went out to pick up the food. I walked ________ because I thought he would leave the food at the gate of my community and leave in a hurry.

As I went to the gate, I saw him ________ in the pouring rain without an umbrella. The rain kept falling down on his face, his foot, and his yellow uniform. He was in his twenties. He looked tired.

“Chicken soup?” he asked.

I nodded and he handed the food to me with shivering(颤抖的) and watery finger.

“Why didn’t you leave ________ to find some shelter from the rain?” I asked.

“I work to bring food safely to our ________. For us, one of the most things is to ________ their needs.” he said with a smile on his face. Then he turned around and disappeared in the rain.

The cold rain kept falling, but a wisp(缕) of warmth rose in my heart. Around us there are many ________ people like him who do their jobs every day, even when their work is really tough. They never forget to bring us convenience and ________ .

About 50 percent of food in the US is wasted. Wasted food produces gas that will cause global warming, and brings other problems like energy emergency. To reduce food waste, people in the food packaging industry are a working to develop products for longer shelf life.

Jonathan Deutsch, a professor of food science, says, “All food packaging is designed to explain the contents, protect the quality, and make sure the safety of the product.” When packaging keeps food safe and fresh for a longer time, less waste happens.

Making food last longer is not easy because different foods need different packaging. Fats, for example, change when meeting air and light. That’s why fatty foods, like potato chips, are always kept in packages which light can’t get through. And cookies are afraid of getting wet. Keeping those snacks in a fully closed package will help them stay fresh and tasty longer.

Packaging can extend shelf life by keeping out gases in the air, like oxygen. Oxygen causes problems for many different foods. So many food packages are designed to solve the air problem. Vacuum-Sealed packaging takes off any oxygen between the food and packaging, which can increase shelf life from a few days to a few weeks. Modified atmosphere packaging is another solution. Unlike vacuum-Sealed packaging, which takes off as much air as possible, this packaging replaces the air with a right mixture of gases. Red meat needs some oxygen to keep its colour, but too much oxygen can make it go bad. This kind of packaging can extend shelf life while keeping the product’s colour.

While packaging can help reduce food waste, people also need to consider the environmental influence of the packaging itself. Scientists are working to develop more proper materials. And more people get to know the importance of reducing food waste. “Unlike many of the challenges we face right now on our planet,” said Shukla from Food & Wine magazine, “Food waste is something that every single person can do something about.”

It’s very popular to travel in modern life. As travelers, we should try our best to protect the environment. Here’s what we can do to be a green traveler.

Make smarter flight choices

Air travel is not an environmentally-friendly way to travel because it uses a lot of energy. If you must fly, be sure to pack light to cut down the plane’s load(负担). And try to book an on-stop flight. Connecting flights usually require longer periods of flying and planes will use more energy.

Respect natural environment

Marked hiking trails(有指示标识的游览步道) are there usually to protect the natural environment and keep wild plants safe.

In beach areas, don’t use products that are harmful to the seawater and try to protect the ocean’s ecosystem.

Support locals directly

Buying handmade products and art pieces created by local people can help hand down cultural tradition and create jobs. Food that is grown locally and things that are sold by local families are often better and cheaper, all helping keep money in local pockets.

Find ways to give back

Consider the ways that you can help the local community and give back while traveling. This can be as simple as picking up litter in a park or volunteering to cleanup a beach. If you’re planning a trip where volunteering is your main goal, make sure you won’t take jobs away from local people.
