Well saying dunno is an error in formal/academic writing. In academic writing you would have to write, i do not know, though.
The Gettysburg Speech is perhaps the most important speech in US history. This speech was delivered by Lincoln in less than two minutes, at the end of the American civil war. That's because the message he wanted to give was fast, clear and didn't need a lot of arguments, because it was evident that it was true.
Lincoln inspired by the principles of equality defended in the Declaration of Independence of the country, declared the end of the war based on the concept that the country was born to be a country of free people and owners of their own lives, the end of the war allowed freedom be offered to everyone, as the founding fathers wanted and fought for it. Thus, Lincoln established that the end of the war would bring a nation united in recovery and truly free.
Starvation is everywhere in the world. In the Untied States of America, in Africa, in China... It's everywhere! Starvation is a big, big problem!
If just one person laid a helping hand in a soup kitchen or even donated food to a canned food drive, less and less people would be starving. It's a matter of how many people out there know about this horrible and growing problem.
Starvation has been around since the beginning of time. Even though it's the better time in America, there is still a lot of starving children, adults, and animals. Especially animals! People find strays all the time.
(That's all I got! Don't worry, all I did was use my head. Good luck!)
