Near Earth Objects

We live on a planet that is constantly struck by asteroids everyday. We have found out about 20,000 NEOs that are 1 million kilometers away from Earth. In the present, we care more about the events that are happening on Earth more than what is happening out there in space. One day when we wake up, an asteroid could strike Earth and wipe out almost all organisms, just like what happened in the Jurassic Age. The dust from the impact covered the Earth in darkness for nearly 100 years, which created the Ice Age. The same event would happen if an asteroid with a diameter larger than 300m strikes the Earth.

This event would be catastrophic! Everyday, NEOs hit the Earth, but most of them are burnt up in the atmosphere. Why should we care about something that is out in space and so far away from us, when there are matters that need to be taken care of right here on Earth? Well, we would never survive an asteroid that could pass through the atmosphere. There are no absolute solution. We could try and deflect, change the course of the asteroid by sending spacecrafts or missiles. That is only a temporary solution. We are save, for now. The Earth's destruction is inevitable, so we have to always be prepared. We could go and colonize planets in space, but our chances for doing so are slim. We could never reach any planets that are outside of our solar system, but it is never bad to hope!

Racism

Racism is defined as discrimination based on skin color, origin. Racism is purely made up by human. We are one entity, and our differences vary trivially.

We fear what we do not understand, and different skin color is a sign of unknown. In human history, the Westerners have enslaved all the people around the world: Asian, Africans, Indigenous people, etc. Everything started there, and the enslaved people are seen as lower class, some see them as animals. Discrimination of black people is one of the most notorious racism. They were treated as lower class than white people back in the 1800's. Black people were "shipped" from Africa to the US to work in cotton plantations. They were treated terribly unequal. They had no human rights, low working conditions, and terrible accommodation.

Even after the Civil War, which intended to free all slaves, black people were still discriminated by the white's society. The KKK, or Ku Klux Klan, was a cult that was formed by Confederate veterans. They were a movement that was against black people, and wanted to purify the US's society.

Hitler's Holocaust was because he was racist against Jewish people. He saw them as inferior and should be eliminated from the gene pool. There were many concentration camps, and the casualty was 6 million people.

Even now, racism still exists in our society. Something that is fallacious and made up by human should be abolished. It creates inequality, discrimination, violence, etc. We are the same, and we should unite to create a better world for all eternity. Unite and stop racism!
