We've had 50+ years of climate change warnings, and nothing has really happened.

We're still not doing much... For example, the percentage of coal consumption is still around 82%, even after minor advancements in renewable sources.

Nobody at the political level is even talking about the need for a reduction in meat consumption, despite scientists being very vocal about this.

I simply feel that this is something that has to come (could come) from "down below."

All those sectors you've mentioned are absolutely problem too. Animal ag is 15-26% of our carbon budget, depending on which source you'll pick. That's already bigger that cement, and almost all of transport.

But animal ag is not just the emissions alone, and not only cows. Just with afforestation potential (land use change of pastures) we'd be able to store our entire 1.5C carbon budget.

This is a short (and incomplete) list of impacts of (animal & industrial) agriculture. It's imho clear from this list that animal ag (which is 75-80% of all ag) is the major culprit.

- Greenhouse gas emissions

- Deforestation (40+% of pastures used to be forests)

- Land degradation

- Water pollution

- Water overconsumption

- Loss of biodiversity

- Antibiotic resistance

- Ocean dead zones

- Inefficient land and resource use

- Ethical concerns regarding animal welfare

- Zoonotic diseases

- Air pollution

- Eutrophication

- Soil erosion

- High energy consumption

- Chemical runoff from pesticides, herbicides and fertilizers

- Destruction of habitats and ecosystems

- Inequality in global food distribution

- Public health risks from foodborne illnesses

- Nutrient pollution

- Strain on waste management systems

- Overfishing (40-70% of plankton gone, sharks 90% gone, fish almost gone)
