1
Cause

人間活動

人間活動

accounts for 25% of GHGs if we include induced deforestation.

2
Consequences

森林伐採

農業

Deforestation is due for 80% to agriculture. It can be considered as a human activity or as a consequence of agriculture of both.
その他の温室効果ガス

農業

The pictures in the background of card 9 should put you on the track!

5
Other possible consequences

化石燃料

農業

Agriculture does not use much fossil fuel, just enough to keep tractors running. Its carbon emissions are high, bu mainly because of methane and nitrous oxide.
CO2排出量

農業

Agriculture does not emit much CO2 except from deforestation. Its carbon emissions mainly come from othe GHGs.
エアロゾル

農業

Spraying crops does result in aerosols and air pollution, but not to the same extent as incomplete combustion from power plants.
炭素吸収源

農業

It doesn't matter if this link is not made, but it is true that agriculture can improve storage capacity through photosynthesis. This is the 0.4% principle (if we increased the soil's capacity to sequester carbon by even 0,4%, we would have a significant impact on CO2).
陸上生物多様性

農業

Here, we are thinking mainly of pesticides (especially Roundup or neonicotinoids). No link with the climate, but an interesting relation to make.

Wrong causes

陸上生物多様性

陸上生物多様性

It would be more logical to link to agricultural yields.
農業生産高の減少

農業生産高の減少

Yes, the yield decline does affect agriculture, but the agriculture card is here to stand for one of the causes of GHG emissions.
