Nowadays, space projects to find extraterrestrial life have been receiving a great deal of public attention.
some people support these programs, the disadvantages will be far more significant
There are various reasons why some people support projects of finding new planets to live.
, since the birth rate is constantly increasing, the world is facing threat from problems of the population explosion.
, baby boom might cause the lack of land and accommodation, which forces humans to resort to alternatives of changing living places to other planets.
, global warming has had catastrophic effects on the green shelter,
as melting ice in both polar or rising sea levels.
means that living on the Earth is increasingly difficult, which leads to a growing number of people desire to have a new place outside the universe to live better.
, there are a number of compelling reasons why we should not spend money on these projects.
, since the cost of space studies is prohibitively expensive, many countries will fail to pay them in the long run. In fact, it will cost millions of dollars for crew, researchers, and scientists involved in
field, leading to budget deficits as an unexpected result.
, by making space travel to discover the same terrain as the Earth, many scientists have responded that the chance of success is very slim. Plenty of evidence suggests that it takes hundreds of millions of years to bring people to the nearest planets, like Mars, but there is guarantee that there is life, not to mention the life expectancy of people is limited, which implies that
schemes will offer little returns.
these programs are not without advantages, the downsides will justify these. By focusing on addressing existing environmental problems, humans might be able to make the Earth friendlier to live.
