Prompt Describe the connection between human activity and environmental changes that occurred from 1900 to the present.

Explanation:

There are so many environmental changes that have occurred from 1900 to present. This is due to the fact that, human race wants to make everything available for themselves.

The changes include

* Loss of biodiversity

* Depletion of ozone layer resulting to global warming

* Land degradation

* Urbanization

The connection between human activity and environmental changes is very apparent when you look at climate change and how the Earth’s terrain has changed in the past 100 years. People cut down an average of 15 billion trees per year (from an article on time.com), which amounts to about 1,815,000,000,000 trees cut down since 1900. This is as a result of technological advancement by humans, and human activity has affected many other facets of the environment. For example, as a result of the increased use of fossil fuels to power machinery, the increased process of extracting natural resources to the point of near scarcity, and the destroying of environments to satisfy human needs, the environment has been suffering greatly. One prime instance of this environmental damage is climate change, which is when the climate changes as a result of pollutants in the atmosphere. These pollutants are a direct result of the increased human activity in the machinery and technology industries, as the burning of fossil fuels and the operating of machinery release carbon dioxide into the atmosphere, damaging the atmosphere. The use of machinery and fossil fuels really began to pick up steam in the 1900’s. So, as a result of increased human activity in environmental affairs since 1900, the environment has suffered greatly, increasing the global climate, decreasing oxygen levels, and increasing the risk of UV ray damage to living organisms.

I got a 90% on this, enjoy :)

i'll tell you everything i know

explanation:

the american entry into world war i came in april 1917, after more than two and a half years of efforts by president woodrow wilson to keep the united states out of the war.

apart from an anglophile element urging early support for the british, american public opinion reflected that of the president: the sentiment for neutrality was particularly strong among irish americans, german americans, and scandinavian americans, as well as among church leaders and among women in general. on the other hand, even before world war i had broken out, american opinion had been more negative toward germany than toward any other country in europe. over time, especially after reports of atrocities in belgium in 1914 and following the sinking of the passenger liner rms lusitania in 1915, american citizens increasingly came to see germany as the aggressor in europe.

wilson, as president, made virtually all the key decisions over foreign policy. while the country was at peace american banks made huge loans to britain and france, which were used mainly to buy munitions, raw materials, and food from across the atlantic. until 1917, wilson made minimal preparations for a land war and kept the united states army on a small peacetime footing, despite increasing demands for enhanced preparedness. he did, however, expand the united states navy.

in 1917, with russia experiencing political upheaval, and with britain and france low on credit, germany appeared to have the upper hand in europe, while the ottoman empire, germany's ally, held on to its territory in modern-day iraq, syria and israel. at this point germany decided to resume unrestricted submarine warfare. its goal was to starve britain into surrender, although it realized that this would almost certainly bring the united states into the war. germany also made a secret offer to mexico regain territories lost in the mexican–american war in an encoded telegram known as the zimmerman telegram, which was intercepted by british intelligence. publication of that communique outraged americans just as german u-boats started sinking american merchant ships in the north atlantic. wilson then asked congress for "a war to end all wars" that would "make the world safe for democracy", and congress voted to declare war on germany on april 6, 1917.

on december 7, 1917, the u.s. declared war on austria-hungary.

u.s. troops began arriving on the western front in large numbers in 1918.

i hope this uwu
