In particular, they claim it may be ethically objectionable to bring into existence large numbers of animals that suffer greatly during their often-short lives in the wild.[7] There are also concerns that even with full terraformation, distinct differences between Earth and Mars, such as gravity, lengths of the day and night cycles, and differing/lacking magnetic fields, would cause harm to many introduced species that have evolved for millions of years under Earth conditions.	./cache/en-wikipedia-org-6049.html	./txt/en-wikipedia-org-6049.txt
