Are Humans Destroying the Environment?

Scroll down to explore a learning path based on this topic.
Playlist Description

Is man destroying the environment? You've probably caught wind of the devastating state of the environment, and mankind doesn't seem to be doing too much by way of creating a sustainable planet. In fact, China alone is burning almost as much coal as the rest of the world combined. By 2017, scientists believe India will burn as much coal as China. When that coal is burned, greenhouse gas emissions are released into the atmosphere to begin eating away at the ozone layer—the precious resource which stops us from frying in the sun—and chips away at the potential longevity of livable Earth. Add preventable oil spills, drinking water contaminations, chemical explosions, and disappearing bodies of water to the mix and you've got one declining environment. What could possibly make such a fate worse? It was all done at the hands of humans.

So how long does Earth have left? Have humans caused irreparable damage or can we still salvage what's left for future generations? Perhaps most importantly, what lessons can we learn from mistakes of the past? This playlist reveals a history of negligence, apathy toward safety, fatal mechanical malfunctions and devaluation of the environment at the helm of our world's biggest unnatural disasters.

Tweet this video! - http://clicktotweet.com/c5y3L Our environment has been the victim of all sorts of attacks. Some of these attacks are natural such as hurricanes and earthquakes. However, there are attacks that are unnatural and man made such as wars, explosions, chemical spills, etc. These attacks usually carry with them heavy price tags as property and lives are damaged beyond full compensation and repair. To see these effects first hand (or as close to first hand as possible) we present to you our 25 biggest environmental disasters of history list for your personal edification. https://twitter.com/list25 https://www.facebook.com/list25 http://list25.com Check out the text version too! - http://list25.com/25-biggest-man-made-environmental-disasters-in-history/ Here's a preview: TVA Kingston Fossil Plant Coal Fly Ash Slurry Spill The Exxon Valdez Oil Spill Pacific Gyre Garbage Patch Jilin Chemical Plant Explosions Castle Bravo The Three Mile Island Nuclear Explosion The Kuwait Oil Fires "Door to Hell" The Palomares Incident Sidoarjo Mud Flow Libby, Montana Asbestos Contamination Deep water horizon (BP) oil spill Amoco Cadiz Eccocide in Vietnam The Al-Mishraq Fire The Love Canal Gulf of Mexico Dead Zone Minamata Disease The Seveso Disaster E-waste in Guiyu, China Baia Mare Cyanide Spill The Shrinking of the Aral Sea The Bhopal Disaster The Chernobyl Nuclear Explosion The Great Smog of '52

Ozone gas (O3) in the upper atmosphere shields Earth from the Sun's dangerous ultraviolet radiation. Since the early 1980's, scientists have been aware that human-made chlorofluorocarbons (CFC's) and other chemicals destroy atmospheric ozone worldwide. The greatest losses have occurred at the poles. Over the Antarctic region, a distinct ozone "hole" emerges in late September or early October. The 2010 Antarctic ozone hole reached its maximum extent on September 26—about 20 million km2, an area twice the size of the United States. Although the size of the annual ozone hole has varied relatively little in the last decade, global ozone levels are slowly recovering due to the international ban on CFC's initiated by the Montreal Protocol in 1987. The United States satellite measurement program for ozone, run jointly by the National Oceanic and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA), has measured Earth's ozone distribution since 1978. This visualization shows false-color ozone measurements in both ultraviolet and infrared wavelengths obtained by the SBUV/2 and HIRS instruments aboard the NOAA Polar Operational Environmental Satellite system. The 1980 and 1987 October averages are from NASA's Total Ozone Mapping Spectrometer sensor aboard NASA's Nimbus-7 satellite. Ozone levels are shown in measurements of Dobson units. The ozone hole represents ozone levels lower than 220 Dobson units. The projections of the size of future ozone holes are based on the work of NASA's Paul A. Newman and colleagues.

Global warming is among the most alarming environmental issues that the world faces today. This phenomenon does not simply involve the significant rise in the earth's temperature but a lot more. The adverse effects of global warming have become more and more apparent since the dawn of the 20th century, with more hurricanes and tropical storms causing massive destruction in different areas around the world, more animal species losing their habitats and becoming extinct, and more people dying because of complications such as heat stroke. Here are 25 alarming global warming statistics. https://twitter.com/list25 https://www.facebook.com/list25 http://list25.com Check out the text version too! - http://list25.com/25-alarming-global-warming-statistics/ Here's a preview: By the end of the century, around 150,000 people will have died of heat related causes. The United States is responsible for 80 % of the total amount of fossil fuel consumed every year. Each year of the 21st century is among the hottest in history. The amount of carbon dioxide in the atmosphere has risen by 34 % since the 17th century. The temperature of the earth will soon become 5.8 degrees higher. Humans release 37 billion metric tons of carbon dioxide every year. The level of carbon dioxide in the 20th century has been the highest in 650,000 years. People dump carbon dioxide into the environment at 1000 tons per second. More than 1 million species have already faced extinction due to global warming. In the near future, around a hundred million people will see 3 feet of sea level rise. The Montana Glacier National Park now has about 30% of its total glaciers from 1910. The average temperature in three large countries has increased at two times the global average. There will be an increase of 7 to 23 inches in sea levels by the end of the century. The United States is the top global warming polluter in the world. By 2050, 15 to 37% of our plant and animal species could be wiped out. Over the past century, the sea level has risen by 10 to 20 cm. 400,000 square miles of Arctic Sea have already melted due to global warming. By 2030, the number of glaciers in the Glacier National Park will equate to zero. Global warming caused $100 billion worth of damage in the United States alone in 2005. The amount of carbon dioxide in the atmosphere has increased by 31 percent. The intensity and duration of deadly hurricanes have doubled since the last four decades. The rate of global warming has accelerated thrice faster over the past 30 years. The annual temperature of the world and the United States is now 1.0 F hotter compared to the temperature a century back. The past nine years have all been among the 25 hottest temperatures in history. Two of the world's hottest temperatures were recorded in the last ten years.
