bet365 live casino games  According to the official website of the North Carolina State University, the official website of the North Carolina State University recently reported，Professor Jennifer M. Landin, a professor at the school, said，Climate change knowledge reserves of college students will determine future habitats、Ecosystem、Species diversity and all aspects of agricultural development。Although the scientific community is increasingly aware of the impact of climate change on the ecosystem and geographical landforms，Most of the university bet365 best casino games textbooks published by the United States after 2010 have reduced the content of climate change。

Langding and others selected 57 college biological textbooks published in the United States from 1970 to 2019 as research objects，The cover of the knowledge of climate change from four aspects，The number of sentences of the theme paragraph of the climate change; the theme classification of the sentence (the greenhouse effect、The influence of global warming、Actions to improve climate change, etc.); climate change paragraphs come to the beginning of the book; charts and data references。

Langding and others discovered，In the 1990s，The content of the content of climate change in American university textbooks has the largest growth rate。The average bet365 live casino games textbook published by 1990 involved in the content of less than 10 sentences involved in climate change。In the 1990s，The median involved in the content of climate change is 30 sentences，At the same time, the sentence of the climate change solution reaches the peak，More than 15%of climate change space。The first 10 years of the 21st century witnessed the growth of climate change research。Higher education also reflects the latest academic achievements; the median number of climate content in textbooks has increased to 52 sentences。But，After 2010, the median number of climate change content in textbooks drops to 45 sentences，The solution of climate problems only accounts for about 3%of the total length of the climate change。In addition，bet365 Play online games Textbooks only show the global temperature and carbon oxide level chart data of the world before 2000，and the evidence of the variety of species distribution after 2000。

In addition to reducing content and quoting outdated data，Climate change chapter in the position of textbooks in American universities continues to retreat。2070s，Climate change chapter accounts for the last 15%of the content of the book; after 2010，This theme only accounts for the last 2.5%。Langding is worried about those teachers who are accustomed to explaining the textbooks in order will ignore the climate change chapter at the end of the textbook。

Researchers also found，Expressing over time，Textbook chapters from describing the principle of greenhouse effects to the impact Bet365 app download of climate change，At the same time, it has greatly reduced the length of discussing how to solve climate problems。Langding said，This content arrangement conveys the pessimistic mood of human beings that cannot solve climate problems。This not only has great misleading，It also promoted the concept of young people's destiny on climate change。

Langding and others hope that the study can ring the alarm for publishers and teachers in the United States。Langding said: "If we want the next generation to truthfully understand how the climate change will affect all aspects of the life of the earth，and many methods for all human cooperation to solve the problem of climate change，We need to incorporate climate change in the teaching category more comprehensive。”
