Stop climate change: Difference between revisions

Revision as of 02:37, 30 December 2024

GHGs (greenhouse gases, such as **CO₂**) are the gases that cause climate change. **This is a pie chart of where they come from.**

Note that a large chunk of emissions are a function of how much new **"stuff" people buy**: *See sections: "manufacturing", "transporting goods", "agriculture".*

Note that half of emissions come from the richest 10% of the world. This *includes* **most people** who live in "first world" countries.

Climate change is mostly caused by burning fossil fuels for energy - and to a lesser extent, by today's agriculture.

But note: Agriculture has other major environmental impacts too, besides just climate change.

Solutions we ultimately need ✊🏻✊🏽✊🏿

Replace ALL fossil fuel energy, with renewables and/or nuclear power
- Not technologically feasible, currently.
  - Would become more feasible if the demand for energy (and vehicles) was lower. This is quite viable, as long as people in first-world discussion "first-world", for lack of a better terminology
    
    Talk: I didn't want to say "developed countries" here, because a less experienced person reading quickly might mistake it for "developing countries" (which is the opposite of what I'm trying to convey). I also didn't want to say "rich countries" because some people might mistakenly think their country isn't rich enough for it to apply to them. So I'm stuck using an old, somewhat improper term: "first-world countries". countries are willing to make some lifestyle changes:
    - We can still have nice things, just not replace them so often
    - Reduce the need for driving
Some lifestyle changes are still needed even if we phase out fossil fuels:
- Stop food waste
- Make the food supply more plant-based (does not require 100% veganism)
- ↑ These are needed to prevent deforestation. See why.

-[[File:us military carbon footprint - Google Search.png|thumb|There are plenty of misleading headlines that compare the US military to much smaller things, making it look so big that you may as well neglect everything else.

-None of this justifies any of the horrible things that the US military does or has done. Just to say that its carbon emissions aren't an excuse to ignore all the other carbon emissions.
-===="Why care about my carbon footprint when fossil fuel corporations are responsible for 70% of all emissions?"====
-Their sales are a function of what people buy. It's 2 sides of the same coin.
-===="But how much do ordinary people's actions really affect the planet?"====
-In richer countries like US, Canada, Russia, etc., the answer is: '''a lot.''' If the whole world lived like the average person there, we would need over 3 Earths.

-We need to change the [[cultural norms that lead to unsustainable living]].
-===="But I heard that carbon footprint calculations are just a capitalist tool to put the blame on consumers instead of corporations?"====
-No.
-* The less we consume fossil fuels, the less money fossil fuel companies can make.
-* If a company is giving you "tips to reduce your carbon footprint", chances are the tips are so insignificant that it would have no real effect on their profit margin. They typically focus on bags, packaging and straws, which are nothing compared to the actual products sold. Even "green" products may involve just as many resources, if not more.
-* Actions that ''actually'' reduce one's carbon footprint involve [[frugalism|buying less stuff]] and [[reduce the need for driving|driving less]].
-* Just because corporations are dishonest, doesn't mean we should throw away the whole idea of accounting for carbon. Even without capitalism or money, the math still matters.
