"Monarchs in the western part of the United States migrate for the winter to California, where they gather mostly among fragrant eucalyptus trees, which provide hospitable living conditions."
These eucalyptus trees, many planted in the 1800's and are now quite large and beautiful, are under attack by many environmental groups for being non-native and others for being a fire hazard. Maybe they did not even winter in California until those invasive trees were planted?
Life is complicated, but in general humans have been becoming much more respectful of the environment as we become more wealthy. The key to preserving the wonderfully complicated ecosystems on Earth is probably to continue as rapidly as possible with our tech improvements (and get back on pace from where we stopped in the 1970's) and to eventually turn all of Earth into a park, a la Bezo's plan. Don't work to shut down nuclear power tech (we have plenty of coal to burn and that is much worse) but help it improve. Support a safe waste storage solution instead of using that problem to shut down future construction.
The other alternative really boils down to a belief that it would be best if humans weren't around. Most humans rightly oppose this view and evolution will tend to support an increase in people with that view in the long run. A religion that has "don't have children" as a belief won't last long.
