By the 1920s competition from the South and Midwest, followed by the Great Depression, led to the collapse of the three main industries in Massachusetts: textiles, shoemaking, and mechanized transportation. This decline would continue into the later half of the century; between 1950 and 1979, the number of Bay Staters involved in textile manufacturing declined from 264, 000 to 63, 000. This spurred an exodus of high-paying jobs from Western Massachusetts, which suffered greatly as it de-industrialized during the last 40 years of the 20th century

It was recognized in the early 20th century that greenhouse gases in the atmosphere made the Earth's overall temperature higher than it would be without them.

12. Controlled burns have a long history in wildland management. Pre-agricultural societies used fire to regulate both plant and animal life. Fire history studies have documented periodic wildland fires ignited by indigenous peoples in North America and Australia. Fires, both naturally caused and prescribed, were once part of natural landscapes in many areas. Studies have shown that between the mid Holocene and the 19th century AD, wildland fires annually burned between 4.5% and 12% of present-day California's total land, for example. These practices ended in the early 20th century when US fire policies were enacted with the goals of suppressing all fires. Since 1995, the US Forest Service has slowly incorporated burning practices into its forest management policies

According to the Dalcroze method, music is the fundamental language of the human brain and therefore deeply connected to what human beings are.

16. The application of fire management tools requires making certain tradeoffs. Below is a sample of some costs and benefits associated with the tools currently used in fire management. Current approaches to fire management are an almost complete turnaround compared to historic approaches. In fact, it is commonly accepted that past fire suppression, along with other factors, has resulted in larger, more intense wildfire events which are seen today. In economic terms, expenditures used for wildfire suppression in the early 20th century have contributed to increased suppression costs which are being realized today. As is the case with many public policy issues, costs and benefits associated with particular fire management tools are difficult to accurately quantify. Ultimately, costs and benefits should be weighed against one another on a case-by-case basis in planning wildland fire management operations
17. Fast and effective detection is a key factor in wildfire fighting. Early detection efforts were focused on early response, accurate results in both daytime and nighttime, and the ability to prioritize fire danger. Fire lookout towers were used in the United States in the early 20th century and fires were reported using telephones, carrier pigeons, and heliographs. Aerial and land photography using instant cameras were used in the 1950s until infrared scanning was developed for fire detection in the 1960s. However, information analysis and delivery was often delayed by limitations in communication technology. Early satellite-derived fire analyses were hand-drawn on maps at a remote site and sent via overnight mail to the fire manager. During the Yellowstone fires of 1988, a data station was established in West Yellowstone, permitting the delivery of satellite-based fire information in approximately four hours
18. The California Gold Rush beginning in 1848 led to dramatic social and demographic change, with large scale immigration from the U.S. and abroad and an accompanying economic boom.

The late 20th century saw the development of the technology and information sectors, punctuated by the growth of Silicon Valley. California's prosperous agricultural industry also emerged; at least half of the fresh fruit produced in the United States are now cultivated in California, and the state also leads in the production of vegetables. Other important contributors to its economy include aerospace, education, and manufacturing. If California were a country, as of 2012 it would have the 9th largest economy in the world and it would be the 34th most populous nation
19. The County of Gorizia and Gradisca emerged as a major center of Slovene culture in the second half of the 19th century. Already in the early 1860s, Slovene replaced German as the major language of education and administration in the Slovene-inhabited parts of the county. Differently from Styria, Carinthia and even Carniola, there was no assimilation pressure against the Slovene culture in most of Gorizia-Gradisca, so the Slovene culture flourished. Since the 1890s, the State Gymnasium of Gorizia emerged as one of the most prestigious educational centers in the Slovene Lands: several prominent figures in Slovenian arts, sciences and politics in the early 20th century received their education in this institution. In 1913, the Gymnasium was divided into three parts, with German, Italian and Slovenian as the language of teaching. The Slovenian section of the Gymnasium of Gorizia thus became the first public high school with Slovene as the primary language of teaching
