3. Considering what you've learned about acid rain formation, do you think Indigenous farmers prior to the 1400s experienced acid rain? Do you think the acid rain caused farming pollutants that led to water and air pollution?

It is difficult to say definitively whether Indigenous farmers prior to the 1400s experienced acid rain, as there is limited historical data on the topic. However, it is possible that some regions may have been affected by natural sources of acid rain, such as volcanic activity or lightning strikes.

As for whether acid rain caused farming pollutants that led to water and air pollution, it is unlikely that Indigenous farmers would have contributed significantly to acid rain formation through their agricultural practices. Indigenous farming methods typically involved sustainable and environmentally-friendly techniques, such as crop rotation and use of natural fertilizers.

Overall, while it is possible that Indigenous farmers may have been exposed to natural sources of acid rain, it is unlikely that their farming practices would have significantly contributed to water and air pollution in the same way that modern industrial practices do.
