Near Earth objects

Imagine: One day, you are happily walking on a street, and the last thing you see is the sky getting dark. Why do you die?
Probably, there things above your head that can kill you. Those things are called "Near Earth Objects".

"Near Earth Objects. Near-Earth Objects (NEOs) are comets and asteroids that have been nudged by the gravitational attraction of nearby planets into orbits that allow them to enter the Earth's neighborhood."

NASA

According to "Earth Impact Effects Program", an 7-meter-diameter asteroid can hit the Earth with energy of Little Boy, an atomic bomb dropped during Word War 2. NEOs hit the Earth everyday. However, since most of asteroids are not really big, they get broken during their way.

-Why should we care about it? 

-None of us will survive if struck by a NEO that is large enough to pass through the atmosphere.

- Why should we care, since we can do nothing because NEOs are far away from our reach and too many to destroy?

- Well, there is always something you can do. First, pray. In case praying doesn't work, there is a temporary solution. Spacecrafts can be sent to calculate and deflect the path of NEOs. However, there is no permanent solution. We are safe, for now.

"It’s simply a question of when, not if, a NEO collides with the Earth."

Professor Monica Grady

Racism

What define people? Their actions or their skin colors?

Racism is the belief that one race is superior to another race. Where does this belief come from?
Xenophobia is one natural factor. People are afraid of who are different from them (different skin or hair color for example).
Another factor is the history of colonization. For instance, Africans used to be colonized by Europeans. Although black people have gained their freedom, the "idea" of colonizing is still around in modern world as an excuse for white people to classify themselves as "superior species".
The racial "stereotypes" have horrible effects.

"Racism can have a lot of effects on a victim. Victims can become angry, bitter or violent. It can destroy a person’s self esteem. It can destroy communities and creates divisions within society."
