From radiocarbon dating in the 1940s to remote sensing techniques (RST) in the 1960s, archaeologists have long been early users of technology. Now, experts can use robots to explore ancient cities underwater. Imaging technologies can show the true colors of ancient statues, and protein analysis tells us what diseases ancient people had. Here are three more of the main tech tools used in archaeology.

LiDAR

Ancient sites and buildings may be hidden under trees, water, soil and other things, making them difficult to find for archaeologists. However, with Light Detection and Ranging (LiDAR), archaeologists can scan different areas and find previously hidden sites. It works by sending laser pulses and receiving data from the surface below. The data can then help produce a 3D image of a buried city. In the early 2010s, archaeologists used LiDAR to find a lost Mayan city of which there used to be little evidence.

Virtual reality

Rebuilding ancient sites is an important part of archaeology. But it's never an easy job, as the original materials are hard to find, and rebuilding may also cause harm to the site. VR technology helps to bring old sites back to life. For example, British archaeologist Morgan rebuilt a Neolithic site in Turkey with VR. She collected data from the site and "rebuilt" the site brick by brick on a computer. Then by wearing a VR headset, she "walked around" the site. "It allowed me to look at the site in ways I've never done before," she told Slate, an online magazine.

Artificial intelligence

There are many mysterious words on the oracle bones of the Shang Dynasty that lake a lot of time for archaeologists to understand. AI can help with this. By quickly analyzing a huge amount of data, AI can find patterns and learn to "read" these words.

Eli Zied was supposed to focus on his grades and his future plans for college at the age of 15. But at that time, he started his own business and created a fashion brand called Habits 365.

Eli's business talents and interests appeared around age 12 when he started buying and reselling sneakers. It inspired him "to create a brand that everyone could relate to," Patch Southampton magazine reported.

It was in August 2017 that he came up with the idea to create his own brand. "Habits influence your life, and the better your habits are, the more successful you will be in the long run," Eh told Forbes.

He created designs and logos for his brand. Meanwhile, Eli brought his older brother Spencer Zied into the company as chief operating officer. Thanks to their early accumulated profits from reselling sneakers, the Zieds gained startup capital to invest in initial inventory and packaging. But one of the difficulties was how to expand their brand exposure. On the first night of their new business, they texted friends and asked them to follow the newly created Habits 365 Instagram account.

They also reached out to influential athletes, musicians and agents through Instagram with offers of free goods in exchange for a photograph or a post. This strategy worked out. Now, even NBA All-Star Giannis has worn the clothes of Habits 365.

For Eli Zied, the teenage CEO, perhaps the biggest challenge is how to balance his study and business. "I do homework and study for exams when I first get home from school and work on the business at the end of the day once my school is completed," said Eli. "That is still my main priority. "

Eli, now an 18-year-old freshman at the University of Wisconsin-Madison, was surprised by the brands success. Habits 365 will be expected to reach 1 million in profit by the end of 2021, he told Yahoo Finance. "I believe that one day Habits 365 will be one of the biggest street wear brands in the world," he told Forbes.

Plastic, a durable material, is probably the definitive 20th century "mod-con". It has proved attractive to consumers and manufacturers. But the tide, now packed with an additional 8 million tons of plastic entering the oceans annually, is slowly turning.

The scale of the environmental problem with plastic waste is astonishing More than 6. 3 billion tons of plastic waste has been produced since the 1950s, more than half of which was produced in the past 16 years, and plastic production is expected to double again in the next 20 years. Despite higher recycling rates, large amounts of plastic leak into the environment. Estimates suggest there will be more plastic than fish in the sea by 2050 and there is evidence that it is present throughout the human food chain. An ecologically and technologically superior replacement for many uses of plastic is long overdue.

Consumers have become keen recyclers. Yet this is not as good an outcome as it seems. Even when plastics are recyclable and put in a recycling bin, the majority still ends up in landfill, causing huge emission problems, or ends up in the sea.

Recycling is a complex, expensive, low-profit business. It is made harder because, although 95 per cent of people in the US and EU markets recycle, only about 30 per cent recycle carefully enough for it to be usable.

Nevertheless, growing demand for alternatives to plastic is running ahead of the scientific breakthroughs. These are needed to ensure the environmental impact of replacing it is a net positive. One popular proposal—using paper instead of plastic if possible—however could exacerbates global warming, a more pressing problem.

Having turned consumers into keen recyclers, governments must ensure recycling work. This will require an internationally joined-up regulatory, environment that ensures manufacturers bear the cost of using non-recyclable or uneconomical materials.

Equally, consumers should continue to demand a circular plastic economy. This would be a world in which unnecessary and eco-unfriendly plastic is completely removed, all plastic packaging is 100 per cent reusable or recyclable. The waste must end.

5G wireless networks are ready to power the cities of tomorrow. However, exact implementation (实施)of 5G will vary from city to city, with each city having its own unique set of priorities, requirements, and objectives.

Since 5G enables countless service possibilities, cities must develop strategies around their specific needs. Business and civic leaders play a decisive role in this process, helping to drive smart city initiatives and ensuring that key infrastructure (基础设施)elements are in place.

Several urban areas, including Los Angeles, Dallas, Houston, Atlanta, and Chicago, are early to benefit from 5G For operators, these large urban centers offer a critical mass of solid infrastructure to support 5G's complex technology requirements.

Now, regional and local governments play a critical role in positioning their cities to become early 5G adopters. They have a growing responsibility to streamline the permitting process, change fee structures, and minimize regulator hurdles in order to enable greater 5G implementation.

Efforts are already in full force by industry players to overcome challenges for a smooth build-out in areas where 5G is needed first. As business leaders take a more active role in ensuring that they are well-positioned to better 5G services, they also increase their ability to transform their organizations into smart companies. Peter Linder, head of 5G marketing for North America at Ericsson, emphasizes the critical role individual leaders can play in making 5G and smart cities a reality. “5G will be introduced in urban areas first, driven by consumer and business's needs,” he says. “Proactive city leaders appreciate the potential value of 5G for developing smart city solutions and will partner with service providers to speed up vital network development. ”

The role of business and civic leaders as stimulators for encouraging 5G adoption is decisive to creating smarter, safer, and cleaner cities. The time is right for urban leaders and business executives (执行官)to work together toward making smart cities a reality.

Tropical Rainforest

Tropical rainforests are a world like none other. Unparalleled in terms of their biological diversity, tropical rainforests are a natural reservoir of genetic diversity. They offer a rich source of medicinal plants and other useful forest products. They are an important habitat for migratory animals and preserve as much as 50 percent of the species on earth, as well as a number of diverse and unique originating cultures. Tropical rainforests play an elemental role in regulating global weather in addition to maintaining regular rainfall, while buffering(缓冲)against floods, droughts, and soil erosion (腐蚀).

Despite their monumental role, tropical forests are restricted to the small land area between the latitudes 22. 5 degrees north and 22. 5 degrees south of equator. The majority of the earth's land is located north of the tropics.

Tropical rainforests are a scarce resource in the 21st century. Whatever carpeted the earth's land surface a mere five generations ago has been reduced to scattered fragments(碎片); today, more than two-thirds of the world's tropical rainforests exist as fragmented remainings. Over half of this forest lies in Brazil, which holds about one-third of the world's remaining tropical rainforests. Another 20 percent of the world's remaining rainforests exists in Indonesia and Congo Basin, while the balance of the world's rainforests are scattered around the globe, in tropical regions

It is based roughly on four forested continental regions: the Ethiopian or Afrotropical, the Australasian or Australian, the Oriental or Indomalayan Asian, and the Neotropical.

A. They take in adequate fresh water and oxygen.

B. In that case, new rain forests are seen to be discovered.

C. Their global distribution can be broken up into four biogeographical areas.

D. Their importance to the global ecosystem and human existence is vital.

E. As a consequence, rainforests are naturally limited to a relatively small area.

F. They store vast quantities of carbon while producing a significant amount of the world's oxygen.

G. The largest unbroken stretch of rainforest is found in the Amazon river basin of South America.
