Probably a good place to begin that discussion would be with some sort of demonstration that this is actually a thing that's happening. It seems like a difficult [1] argument to construct, so you should probably get on that.

"the exponential growth driven by our financial system's need for constant growth"
I've updated the original comment.

"In tracking the effects of human activity upon the Earth, a number of socioeconomic and earth system parameters are utilized including population, economics, water usage, food production, transportation, technology, greenhouse gases, surface temperature, and natural resource usage"

Those yields are fully dependent on fossil fuels, agree. But the methods used are extremely destructive (soils, biodiversity, pollution, energy ...).
That's too why the reform of agriculture (and switch to plant-based diets) is so desperately needed, and pronto.
That is completely untrue. We’ve certainly not done enough but the world of 40, 20 and even 10 years ago was much worse. Unfortunately most of the changes have been ones forced on individuals while businesses and governments continue to pollute and cause damage.
The change has to come on both levels.
Let's not use it as an excuse to do nothing.

Avoiding meat and dairy is ‘single biggest way’ to reduce your impact on Earth
We could have taken action even 10, 20, or 40 years ago, but so far, we have done nothing significant to prevent it from happening.
The longer we wait, the more expensive and complicated the solutions will become. Politicians are often reluctant to make unpopular moves that might anger their base, so they tend to focus on short-term goals rather than long-term sustainability (though Bernie might have been an exception, imho). We are searching for solutions that maintain the status quo.
One of the most significant issues is the exponential growth of the human population driven by our financial system's need for constant growth. Yet, we have not even begun to start discussing that.

Those few who'll somehow manage to stay alive.
