Say you're out for a walk in the woods. 1.. Nor can you tell the direction from which you've come. You're lost. How can you survive? Here's the good news: You don't need to be a survival expert to find your way back to civilization. Just stay calm and remember these tips. Pinpoint (定位) your location.
Take a good look around. What do you see? 2. pinpointing your location will be difficult. If possible, find higher ground, giving yourself a better view of the surroundings. Otherwise, you may end up walking directionless and possibly in circles.
3..
While traveling through the wilderness, be observant. Look for old campsites, fishing line, food bags, cigarette ends, plastic water bottles, or any other kind of litter. If you find any such evidence, examine your surroundings to determine which way they went.
If possible, stick to open country.
4.. This type of terrain (地带) is often a result of farming or logging (伐木), which may put you closer to other people. Plus, being out in the open makes it easier for you to be spotted by a low flying aircraft. Be sure to have something ready to signal with in case a rescue plane flies nearby. Travel downhill.
If you are lost in hilly terrain, your best choice is almost always to travel downhill. People tend to settle in valleys, usually close to water. 5., head down and out of the mountains. Besides, you can cover more terrain and conserve energy traveling downhill.

Nola (August 21, 1974 -November 22, 2015) was a northern white rhino（犀牛）who lived at the San Diego Zoo Safari Park near Escondido, California. At her death, she was one of only four remaining northern white rhinos in the world. The other three lived in Kenya. World Rhino Day, held on September 22, is to raise awareness of the less than 30,000 other rhinos left on Earth.
“Rhinos need our help today, not tomorrow,”Nola’s lead keeper Jane Kennedy said. “Last year we lost over 1,200 rhinos just in South Africa. If we continue to lose more than 1,000 rhinos a year, in 10 to 20 years all the rhinos on the planet will be gone.”
“Unfortunately, most animals are in danger of dying out because of humans,” Kennedy says.“ Humans have either poached（偷猎）animals, or because there are over seven billion of us, we’ ve taken up too much of the world’s resources ”. Poachers illegally hunt rhinos for their horns. They sell the horns for thousands of dollars per pound, to be used for art, jewelry, and decorations.Experts believe that one rhino is poached every eight hours.
In 1975, the San Diego Zoo Institute for Conservation Research started the Frozen Zoo, a program through which researchers have collected cell (细胞) samples from more than 8,000 different types of animals, including the northern white rhino. Scientists hope that by studying the rhino cells, they will get greater understanding of it, and will find ways to increase its numbers.
Jane Kennedy describes World Rhino Day as “a celebration of rhinos along with an awareness campaign for everybody across the world to know that rhinos need our help.”At the San Diego Zoo, children and adults are welcome to visit and speak with zookeepers to learn about rhinos. But you don’ t have to live in San Diego to celebrate World Rhino Day. It is observed around the world, with zoos and wildlife parks holding special events and programs to teach people about rhinos, and enable them to see the animals up close.

Does it make sense for countries to invest billions of dollars in space programs when millions of people in their country are living below the poverty line? Many people ask this question and I almost tire of answering it.
Let's talk about Duchenne Muscular Dystrophy (DMD) first. This is a terrible disease in which the victims progressively lose the ability to control their body. It affects almost only boys and shows itself when the boys are around age 5. They're wheelchair-bound by age 12, and will be dead before their 30th birthday. There is no cure. However, there are treatments. They're based on crystalline (晶体) protein structures, whose formation is adversely (不利地) affected by the presence of Earth's constant unidirectional (单一方向的) gravitational field. However, according to a study conducted by the Japan Aerospace Exploration Agency (JAXA) on the International Space Station (ISS), crystalline protein structures form regularly in microgravity conditions, which allows for targeted drugs designed to "double these boys' life spans (寿命)".
And you want to talk about feeding the hungry? We have space lettuce (生菜).And it's structurally and nutritionally equivalent to Earth lettuce. Space is pretty much everything there is, which means you can make a lot of lettuce in space. In fact, one of the potential growth markets in lunar colonization (月球殖民) is food trade. Food can be mass produced and sent to Earth to feed the hungry. By the way, as far as I am concerned, as for feeding the hungry, food distribution is the issue rather than food supply.
Space exploration is one of the best things that humanity has ever done.
