It is sad to see these fires raging around the world. To some extent, fires have always been and now with access to more media, we are more aware of them. A fire can start in the amazon and in an hour we know about it, unlike 10 or 20 years ago, where it would be a lot harder to learn about such things.

This being said,

The over farming and changing climates play a HUGE roll in the increased fires.

Farmers in order to increase the production of livestock like beef, to feed a population that is grown, clear cut miles of forest to make grazing fields. This then alters the weather patterns. Other farmers pull water from rivers to help integrate their fields, shrinking natural waterways, this also affects natural weather patterns. So More people farming, clear-cutting forests, also burning bush or wood they clear cut, more human activity in the forests, campfires, cooking, living and not doing sustainable practices leads to an increased risk of fires that grow then burn threw forests that were once very wet, but now only somewhat due to the change of weather patterns.

I do have faith that humanity will rise from this period of evolution and soon, I hope, work together as a planet to tackle large interconnected issues like this. We only focus on boarder lines... but to save the planet we have to look beyond borderlines and walls and see us all as one people. :D
