"A new census that shows that Earth is host to a staggering 3.02 trillion trees — more than scientists expected.The most recent estimate only counted 400 billion trees, reports Rachel Ehrenberg. Because prior studies used satellite technology alone instead of including data from on-the-ground tree density studies, writes Ehrenberg, they missed the mark. They also estimate that since human civilization began, 45.8 percent of all trees been lost."

"In the heart of Thailand’s most populous city, an oasis stands out from the urban landscape like a great “green lung.” That’s the nickname given to Bang Kachao—a lush protected area that has escaped the dense development seen elsewhere in Bangkok. The city is built on the alluvial plain of the Chao Phraya River. Toward the southern end, near the Gulf of Thailand, is an old meander that never quite formed an oxbow lake. That meander traces the boundary of Bang Kachao, which TIME magazine once called the 'best urban oasis' in Asia. According to a travel story in The New York Times, Bang Kachao is gaining popularity among tourists lured by bike tours, a floating farmers’ market, and the relaxed atmosphere."

This scoop shows an example of built environmental space. The highly urban and crowded Thailand has little green space. So why is this massive green park looking landmass there? Its a strictly environmental section of land to help water flow into the ocean. The people call it the "green lung" because its plants give off oxygen and provide a contrast from its urban sprawl. This article shows the importance that should be placed on having more strictly environmental places in big cities.

It's interesting to see the mixture of natural and manmade landscapes in this image. Humans have an enormous influence on the world around us- we have moved entire rivers for our own purposes, reshaped entire regions. In China, we have literally made it rain. Therefore, it's nice to see remnants of the rich environments that used to cover the urban sprawls of many of the world's largest cities, like Central Park in New York. Bang Kachao in Bangkok is another example of this, a reminder of the richness of the region before it was overwhelmed by the urban development that has characterized Bangkok over the previous century. The oasis serves as a valuable tourist attraction, as Westerners come to enjoy the bike trails and small farming community within Thailand's green lung. Leave it to hipsters to travel halfway across the globe just to enjoy nature within the confines of one of the world's largest cities.

This showcases how important physical geography is. This "green lung" breaks up the high urbanized Bangkok. This helps the environment thrive and helps to cut down of emissions that affect climate change which is a problem in some areas.

"When the Minute 319 'pulse flow' began in March 2014, it was not clear whether the effort would be enough to reconnect the Colorado River with the Sea of Cortez. Some hydrologists thought there might be just enough water; others were less optimistic. It turns out the optimists were right, though just barely. For the first time in sixteen years, the Colorado River was reunited with the Sea of Cortez on May 15, 2014." Via Mike Busarello's Digital Storybooks

"How deep is that icy blue water on Greenland's ice sheet? Dr. Allen Pope, of the National Snow and Ice Data Center, is using data from the NASA/USGS Landsat 8 satellite to find out. In this video, Dr. Pope shares what he sees when he looks at a Landsat image of the Greenland ice sheet just south of the Jakobshavn Glacier.

"Mount Tavurvur, on Papua New Guinea's New Britain Island, erupted on August 29, 2014, throwing ash (gray-brown areas of September image) over surrounding areas. Its last major eruption was in 1994. Tavurvur is a stratovolcano, a volcano consisting of alternating layers of lava and ash, and is located along the eastern edge of the Rabaul Volcanic Complex. Simpson Harbor forms part of the much larger (mostly submerged) Rabaul Caldera." Tags: disasters, remote sensing, Oceania, Papua New Guinea, physical.

There may not be may words on this article but a picture can speak a thousands words as I've seen when looking at these pictures. The climate changing is not only affecting the way people live but it is also affecting the structure of the world's atmosphere such as the melting glacier in Peru called Qori Kalis. The ice and glacier has retreated so much that the ice has melted and created a small lake right in the middle where the huge glacier used to stand. What is going to happen to the work if these type of disasters keep occurring? What other types of physical changes will occur? Any type of change in the land can affect how people live, how they find shelter and any other aspect of living. These type of physical changes are not only happening far from the United States but also in the United States such as California. It is important to look at these 302 photos because it really put life into perspective, showing how something can easily change over time. |
Censo de árboles está en 3.02 trillones de arboles
Suena como mucho, pero con en realidad son pocos para tanta gente.
