Answer:
Air is present in the soil and that is good for the plants that grow in that soil.
Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner.
Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves.
The feelings of the indigenous people tend to vary a lot about this topic.
Some of the indigenous people are very hostile to any foreigners in their land, so they would not hesitate to attack, and even in some cases kill.
There are some that feel it as an usurpation of their daily lives, and do not see the tourists very fondly, but are not making any real problems, just avoiding contact.
And there are some indigenous people that actually saw a nice opportunity to modernize and make a profit of the tourists, so they are using their survival skills in the wild in their advantage, and they are very welcoming towards the tourists and encourage them to come.
