Human future is in the universe

The cause of global warming is in the economic activity in the ground.
A problem will be solved if all economic activities are performed in the universe.
If it comes out to the universe, infinite sunlight energy can be exploited.
The fossil fuel of oil and coal is unnecessary.

Human beings have already got the technology for coming out to the universe.
The road in the ground, and the labor and expense of building construction,
If it turns to space development,
Almost all economic activities could be moved to the universe in about 50 years.
Any the earth becomes a star in which people cannot live.
It is useless even if it makes a road and a building to the earth.


An orbital elevator is required in order for human beings to actually go away to the universe frequently.
With the present rocket, expense starts too much, and energy efficiency is also too bad.
The theory of an orbital elevator is also becoming concrete rapidly.
Soon, it is at the time of utilization.
