Ye still remembers the moment she saw snow leopards (雪豹) at Sanjiangyuan
National Nature Reserve a year ago. On that day, the 15-year-old girl was heading
down a mountaintop with her family. Suddenly, they saw two snow leopards near the
Lancang River. “They have blue-green eyes and long fluffy (蓬松的) tails. They look
so cool!” shesaid.
Since the mid-20th century, the area of snow, grasslands and lakes in
Sanjiangyuan has become smaller because of climate change and human activities.
Manywild animals have diedout.Snowleopards are in danger ofextinction.
On Jan 24, 2003, China set up Sanjiangyuan National Nature Reserve to better
protect the area and thewildlife there.
This year marks the 20th anniversary of the setup of the reserve. In these years,
the population of wild animals has been rising.About 70,000 Tibetan antelopes (藏羚
羊) now live there. And more than 1,000 snow leopards can be found in the area,
6higherthan the global average.
Local people have improved their understanding about environmental protection
over the years. In Nangqen County, most people live on selling caterpillar fungus (冬
虫夏草) they’ve found in grasslands.According to Palden Wang, a 22-year-old young
man, people used to carry food with them in plastic bags and left the bags behind, but
now they are regularly called on to pick up waste on the grasslands. “People would
also take their food waste down the mountains,” he said. “As Gen Zers, we should

Wrapping paper (包装纸) may have “paper” in its name, but that doesn’t mean it
can berecycled. 6 Try thefollowing advice to reduce wrapping paper you throw
8away.
Reuse what you have. 7 It’s reported that the U.S. produces 4.6 million
pounds of wrapping paper every year, and 2.3 million pounds of that stays in people’s
homes, waiting to bereused.
Use different materials. 8 Choose basic brown thick paper that can be
made upwith leaves, pinecones (松果)or markers. Reuse newspapers, oldposters and
children’s school artworks as wrapping paper. There are plenty of other eco-friendly
alternatives (替代物)to wrapping paper.
9 Use baskets, gift boxes or bags, tea towels, and more to show your
presents. Learn the Japanese art of wrapping, using beautiful knots to fasten colorful,
reusable cloth in attractive ways. This way, you’ll have no wrapping paper waste to
deal with.

Driving a car, buying clothes-lots of things you do send out CO2 into the air. But
didyou know that thefood you eat every dayplays abig rolein your carbon footprint,
too?
According to an Australian website, about one-third of the world’s carbon
emissions come from agriculture (农业) and food. To create fewer carbon emissions
from food systems, the whole process should be thought about – including growing,
processing, transportation and waste.The website provides someideas that can reduce
carbon emissionsin food systems. Here are two examples.
Smartfertilizers (肥料)
When people make traditional fertilizers , they need to burn coal. That causes lots
of carbon emissions.At the same time, fertilizers are often overused, creating greater
land pollution. Now, some companies are making smart bio-fertilizers. They let
microorganisms (微生物) live together with crops. This not only reduces carbon
emissionsbut also helps theecosystem become healthier.
Vertical farming
10Vertical (垂直的)farms take upsmall parts ofland and grow crops in a controlled
environment. This way of farming helps to save land so that more forests can be
grown. Some new vertical farms also use energy-saving LED lights to produce
year-round crops. Compared with traditional farms, these new types of farms use less
water and labor.They can avoid wasting both resources and manpower.
