Explanation:
The 20th century saw the largest transformation of the world order since the Fall of Rome: global total fertility rates, sea level rise and ecological collapses increased; the resulting competition for land and dwindling resources accelerated deforestation, water depletion, and the mass extinction of many of the world's species and decline in the population of others; consequences which are now being dealt with. The average global temperature on Earth has increased by a little more than 1° Celsius (2° Fahrenheit) since 1880; Two-thirds of the warming has occurred since 1975, at a rate of roughly 0.15–0.20 °C per decade.[5]The 20th (twentieth) century was a century that began on January 1, 1901[1] and ended on December 31, 2000.[2] It was the tenth and final century of the 2nd millennium. Unlike most century years, the year 2000 was a leap year, and the next century leap year in the Gregorian calendar after 1600.
