4 . Gear for Sleeping Outdoors

Whether you’re camping or backpacking, how can you increase the odds (n.机会) that you’ll sleep soundly in the outdoors? A good start is to have the right gear:

·Car camping bags are typically cut wider, offering homelike and more roll-around room but less efficiency for retaining body heat (not so good on extra-chilly nights).Some rectangular (adj.长方形的) styles can be unzipped (adj.未拉上拉链的) to use as a quilt on milder nights.

·Backpacking bags are mummy shaped for a closer, warmer fit, and are usually lighter in weight. Many are filled with goose or duck down, which compresses (v.压缩) more readily than synthetic( adj.合成的) fill.

Sleeping pad: There are three types of sleeping pads — self-inflating (adj.充气的), air and closed-cell foam (n.泡沫塑料). When car camping, weight is not an issue, so you can enjoy a thicker, wider pad or mattress for comfort. When backpacking, weight is crucial, so a super-lightweight air pad or closed-cell pad may be your first choice.

Pillows: Bring one from home or use a small foam or inflatable camp pillow. Some sleeping bags have a pocket to hold a pillow or folded up clothing, such as a down jacket or fleece sweater.

Eye mask and earplugs: Eye masks are especially helpful when camping in northern latitudes (n.纬度) in summer or in campgrounds with surrounding light. Earplugs block out noises ranging from your tent mate’s snoring to rustling sounds in the bushes.

5 . Extreme land use combined with warming temperatures is pushing insect ecosystems toward collapse in some parts of the world, scientists reported Wednesday.

The study, published in the journal Nature, identified for the first time a clear and alarming link between the climate crisis and high-intensity agriculture and showed that, in places where those impacts are particularly high, insect abundance has already dropped by nearly 50%, while the number of species has been reduced by 27%.

These findings cause huge concerns, according to Charlotte Outhwaite, the lead author on the study and researcher at the University College London, given the important role of insects in local ecosystems, pollination (授粉) and food production, and note that losing insects could threaten human health and food security.

“Three quarters of our crops depend on insect pollinators,” Dave Goulson, a professor of biology at the University of Sussex in the UK, previously told CNN. “Without insects, crops will begin to fail. We won’t have things like strawberries. We can’t feed 8 billion people.”

Scientists say, extreme land use has a link with the climate crisis. Clearing natural habitats for agriculture can dramatically change the area’s local climate and cause temperature extremes. Researchers found evident declines in insect populations in warmer areas, particularly in the tropics. They concluded that in areas with less agriculture, less climate warming, and a nearby natural habitat, insects only declined by 7%, compared to the 63% decrease in areas with less natural habitat cover.

Outhwaite told CNN there are things we can do to help prevent this crisis, like planting more native species and wildflowers, and reducing chemicals used in gardens. “It’s also probably a good idea to think about where the foods that we are buying are being sourced from,” Outwaite said. “So if they’re being sourced from tropical countries, there’s probably going to be a high impact on biodiversity there.”

6 . Homeless animals are usually left without a permanent home when their owners give them up or they’re found on the street. With millions of animals living in shelters every year, there aren’t enough people to take them in.     1     If you’d like to help homeless animals, then there are tons of ways to do so.

When you adopt an animal from a shelter or rescue group, you save two lives.     2    , but you’ve made room at the shelter for another homeless cat or dog. There’s nothing more rewarding than adopting a pet who knows what home life is like and has been missing it — until the day you bring that pet home. Adopting truly makes you a hero.

Whether you like rolling up your sleeves and cleaning cages, socializing with a few of your kitten friends or working with numbers, your skills and interests can make a huge impact on the lives of homeless pets in your community.     4    . Shelters and rescue groups rely on foster (收养的) families to take in dogs and cats on a short-term basis. No matter what you like to do and what you’re good at, there’s a volunteer job for you.

    5    . Consider paying it forward by sponsoring (发起) a pet’s adoption or donating food, cleaning supplies, blankets or towels to your local rescue. You can also help animals right from your computer or phone by donating items from the Best Friends Amazon wish list.

7 . The sound of my mother preparing breakfast fills the house — my morning alarm.

As I drag my body toward the kitchen, I’m greeted by my mother standing over the stove. She effortlessly cooks a dish that blends Western and Eastern styles, a beloved breakfast classic in our family. This is my grandmother’s recipe, which reflected her upbringing.

Since my grandmother’s passing, I’ve become more aware of my mother’s aging and her dedication (奉献) to cooking for us. She has cooked for her family for more than 30 years, dividing her time between three countries — Korea, Canada and Germany. When my parents visit us from Korea, they stay with us for several months. My mother helps around the house, showing her cooking skills to provide delicious meals for me, my partner and our kids. In alternating years, she and my dad will travel to Berlin to spend a couple of weeks with my sister and her partner.

According to Statista, most Canadians claim to spend between 31 and 60 minutes preparing an average weekday dinner for themselves and others in their household. Ten percent of respondents to the 2022 survey stated that they spend more than an hour preparing their evening meal. My mother belongs to that 10 percent.

Her cooking extends beyond the kitchen, starting with careful grocery shopping trips where she examines produce (农产品) and finds the best deals. She takes everyone’s preferences and needs into account. The meal she creates becomes a ritual (仪式), bringing the family together to connect and share. Helping her out in the kitchen demands a great deal of patience. Yet, I know it’s her way of expressing love.

As I chop the vegetables, she glances over and notices that my carrots are not equally sized. She pushes me aside to take over the task.

“Just do the dishes.”

8 . There is growing evidence to show that our past knowledge about Mars was not always the case. Now European researchers say they have discovered the first evidence of a huge groundwater system that once existed below the planet’s surface.

A new study was carried out by Francesco Salese and his team, who studied images of 24 deep craters (n.弹坑) in the northern half of the Red Planet. These pictures were captured by ESA’s Mars Express orbiter (n.宇宙飞船), which was launched in 2003. The study provides the first geological proof that Mars once had a “planet-wide groundwater system.”

According to Salese, scientific evidence already suggests Mars was once a watery world. His team says the images showed that large amounts of successive groundwater activity connected the areas they studied. Evidence of basins and coastlines was also found on the surface of Mars, supporting the idea that water was once present. He added that all the basins seemed to reach about the same height.

Scientists have yet to find out what happened to all that water. And the complex history of water on Mars has linked to whether or not life ever existed on it. During the latest study, researchers also discovered evidence of minerals within some of the identified (adj.被识别的) bodies of water.

The researchers say the findings adds weight to the idea that the water basins on Mars may have once held the materials required to support life. Some of this material could still be buried on Mars, providing possible evidence of life during future exploration. Francesco Salese believes the latest findings could also help us learn new things about our own planet.
