While saying that indigenous people are inherently more connected to nature is at best iffy however I think the point the comic was trying to make is that on a general basis indigenous are (or were depending on how much of their culture and history has been destroyed) more knowledgeable of the lands that they have been inhabiting. More specifically compared to the colonisers that invaded their land.

I see this as racist rhetoric, and I think the point of the comic was to be divisive. It's not that I don't understand the reasoning, it's that I'm looking at it from a step back.

Like if I made an anti-crime meme, and tossed in that blackmen are convicted, and charged with more crimes, the racism would be a lot more apparent because it's promoting negative bias towards blacks.

But this shit isn't any less racist, it's just more palatable.

you have some of a point here, and yeah, for various reasons, including marginalization, its resulting societal standings, and simply the lack of opportunity to industrially fuck up the landscape, indigenous people do in fact tend to end up as better stewards of the land. however, suggesting that this is because they're born special and aren't just following a different culture and incentive structure is a slippery slope that tends to end up in ethnonationalism on the part of whoever colonized a given piece of land first.

colonialism is absolutely a problem to this day, but it's not the only problem there is. while eco-fascism can go to hell, simply opposing it does not automatically clear your ideology of any problems.
