ecological

adj

1. Relating to ecology, the interrelationships of organisms and their environment.

   “Bats host many high-profile viruses that can infect humans, including severe acute respiratory syndrome and Ebola. A recent study explored the ecological variables that may contribute to bats’ propensity to harbor such zoonotic diseases by comparing them with another order of common reservoir hosts: rodents.”

   “To get doomier still, there’s also the pertinent question of whether, given current ecological speculation, the human race will even survive beyond the next century or so – an uncertainty which makes applying one’s imagination to a 22nd or 23rd Century rather academic.”

2. Not harmful to the environment.
