Cyanobacteria, also known as "blue-green algae", are the unicellular organisms which are able to produce oxygen.
Approximately 540 years ago, the atmosphere was very poor on oxygen. Cyanobacteria are thought to be responsible for the oxidization of the atmosphere back then, in an event known as <em>"The Great Oxygenation Event"</em>. As a result, Earth's life forms suffered drastic changes in their composition, as they evolved from being <em>anaerobic</em> to becoming organisms <em>highly dependant</em> on oxygen. The oxygenation of the atmosphere would eventually provide the adequate environment in order for the <em>Cambrian Explosion</em>, or the first diversification of living organisms, to happen.

Woodrow Wilson and Secretary of State William Jennings Bryan came into office with little experience in foreign relations but with a determination to base their policy on moral principles rather than the selfish materialism that they believed had animated their predecessors' programs. Convinced that democracy was gaining strength throughout the world, they were eager to encourage the process. In 1916, the Democratic-controlled Congress promised the residents of the Philippine Islands independence; the next year, Puerto Rico achieved territorial status, and its residents became U.S. citizens. Working closely with Secretary of State Bryan, Wilson signed twenty-two bilateral treaties which agreed to cooling-off periods and outside fact-finding commissions as alternatives to war.
In a statement issued soon after taking office, Wilson declared that the United States hoped “to cultivate the friendship and deserve the confidence” of the Latin American states, but he also emphasized that he believed “just government” must rest “upon the consent of the governed.” Latin American states were hopeful for the prospect of being free to conduct their own affairs without American interference, but Wilson's insistence that their governments be democratic undermined the promise of self-determination. In 1915, Wilson responded to chronic revolution in Haiti by sending in American marines to restore order, and he did the same in the Dominican Republic in 1916. The military occupations that followed failed to create the democratic states that were their stated objective. In 1916, Wilson practiced an old-fashioned form of imperialism by buying the Virgin Islands from their colonial master, Denmark, for $25 million.
That is because the Czar knew that fighting the Austria-Hungary empire and Germany was inevitable and war was brewing. Of course, Russians did not see the end of the war due to the Bolshevik revolution that had them retreat from the war and cease their participation and overthrowing the king.
