My answer to What is the use of discovering habitable planets if we don’t take steps to reach them?
Answer by Desmond Last:
We should make Planet Earth habitable before we look for other Planets to destroy.
NASA should use its expertise and budget to promote new systems for supporting life on Planet Earth that do not destroy life.
We have not been able to find a system of life support for mankind that does not destroy it.
We do not have a system for predicting the effects of the accelerating rate of change of our Planet’s bio-system.
What is the point in sending manned and unmanned space probes to look for habitable Planets when mankind is unlikely to survive the next 50 years?
I believe that there are other ‘humans’in the Universe who must shake their heads in disbelief at how good we are at killing each other and so bad at supporting life.
NASA has also been involved in researching and putting weapons into space – that too should not be allowed.
How are NASA space projects going to launch and return each safely as Climate Change gets worse?
