We ar limited in this same planet. The same space we are living. And We all know the earth have the limited resources. Which means the resources would be all used one day. It is far in the future. But if human do not have a solution for this we would all be history while that day comes. Imagine if it is the end, we would all become the dust in such one great space. 

This planet have more than 7.2 billion people. However we are totally different. Some of us even have never get out of this city. And then after 70-80 years, they die without any thing worth to be remembered. And some of us have visit many places of this country. And some people have good memory around this planet. We should use every minute in our life to enjoy living. We are small in this world.As small as a dust in the desert. But we should live every second worth. Doing things worth to do. Then we would not be regret for the life. If we see through this world from the outer space. The nine planets in this space. There is only one have the life. But what iis it like in the outerspace? Would it be different? If there is any place  some people living just like us? Or we are just living in one space and there are still many others?All these questions filled in my head. And I think this is one huge question worth millions of people work on it for several years. It is worth to be tyhinking. 

Any way most of us are still busy working for living in this space. We live on the food and we have to keep on working every day. Enjoy every day of living.
