Near Earth Objects

Near Earth object (NEO) is the object of the Solar System, but its orbit brings it closer to Earth. All NEO must have perihelion less than 1.3 AU. They include thousands of asteroids near Earth (NEA), the Near Earth comets, and some spacecraft orbiting the Sun, as well as some asteroids big enough to watch before they hit the left land. Many scientists agree that the impact of the past have an important role in affecting the geologic history and biology of the Earth. NEO gradually getting attention from the 1980s by the warning about the potential dangers of some asteroids or comets have orbits very close to the Earth, and the research track of them began to rise.

NEOs is very dangerous because on my research, I found http://khoahoc.tv/khampha/vu-tru/58211_tieu-hanh-tinh-khong-lo-khong-gay-nguy-hiem-cho-trai-dat.aspx . The Giant asteroid danger for the Earth.

 

This video will show you how the Giant asteroid danger for the Earth.

I think we should donate money for NASA to study about NEOs. That's one ways to stop NEOs because that's natural no one can stop it just can prevent time slowly.

Racism

Racism is often defined as a belief or doctrine that inherent differences in biology between different races of humans decided achievement and personal development, with the consequence that his race Vietnam trade and dominion over other races. On the newspaper, I found that in the United States is damage 2000 billions USD per year because of racism. ( because they are not real U.S, so no one interview that people, then they just their name and many company interview them)

RACISM still EXISTS.

There are three types of racism:

- Individual racism

- Institutional racism

- Cultural racism

This is top 10 Most Racist Countries in the World.

10. Indian 

9. Pakistan

8. Russia

7. Israel

6. Germany

5. Japan

4. Rwanda

3.Australia

2. United Kingdom 

1. United States of England

Based on my research, I found some causes of racism. There are : instinctive reaction for species protection, fear of loss and displacement, ignorance, lack of self love, feeling of unworthiness and desire to feel superior.

And the effects of racism aren't small problems. The people who suffer racism would be bitter, angry and violent.And this is real example in history : Emmett Louis Till (941 - 1955)

Finally, I hope you fight people who are racism. We should share education for everybody and propaganda everybody shouldn't racism on Internet and social.
