| Gourmet said: Methane is actually MUCH worse than this. CO2 is but plant food, burning petrol actually makes vegetables and aquatic autotrophes grow faster and healthier all around the world, which by itself decreases the CO2 and counterbalances any effect after some time. And yes, global warming is mostly a myth the way it is usually presented. |
The problem with this is environments that sequester a lot of carbon from the air such as sub-Arctic/Arctic (up to 50% of the Earth's carbon is here), and rainforest are being destoryed. When these environments are destoryed, they release the sequestered carbon into the atmosphere and the new environment (such as agricultural land) isn't as good as storing carbon. The effect cannot be counterbalanced if you remove the factors that create the counterbalance and/or overwhelm the counterbalance.
Anyways, since OP mentions agriculture and livestock. On top of methane you also have N2O which about a third comes only from agriculture and is far more potent than CO2 and methane. There's a variety of sources that contribute to overall warming so it's important to focus on the big picture as a whole.
