What efficient means: switching from ecologically expensive foods like beef to lower impact vegetarian diets.
What efficient does not mean: using vast quantities of fertilizers, herbicides and pesticides.
Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Wait, you're telling me the galaxy brains over at big-ag, who say that factory farms are actually good for the world, because caging up animals lowers land requirements... they lied to me?
Why is an ever growing population considered unquestionably good?
If we make more food so we can make more people, it will accelerate the destruction of the planet. No amount of electric cars and vegan diets can do anything but slow down the destruction by a small degree. We can't just wipe out natural environments to mine and farm for the niceties of modern human life and expect the web of life to continue to support us and we cannot survive without this web of life.
I think our species (in aggregate) is no more intelligent than bacteria on a petri dish, we're dumb animals with cell phones. An actual intelligent species would be smart enough to avoid outgrowing it's environment leading to it's own demise. Population is one of the greatest filters.
