The main reason why the Amazon rainforest smokes is because of human activities such as deforestation, agricultural activities and mining, which lead to forest fires.

Eating more meat will increase the demand for livestock, which requires a large amount of pasture planting, and these pasture plantings often require large tracts of land.

In order to free up land to raise livestock, people will cut down forests, which will destroy the ecological balance of the Amazon rainforest and increase the probability of fire.

Therefore, if we eat less meat or choose plant-based foods, we can reduce the demand for livestock, thereby reducing damage to the Amazon rainforest and avoiding its smoking.
