This is my problem.
I think about how a crow matters. Then that crow needs grubs and worms. So the soil must be good soil that's not polluted or eroded or dried out. There must be insects and creepy crawlies.
So the temperature can't keep increasing.
I think about how a crow matters. Then that crow needs a place to have a nest. That means he needs to have trees. The trees need the fungi and the fungi need the soil.
So the agrochemicals and development have to stop.
I think about how a crow matters. Then I realise that eggs have to be strong enough. Certain agrochemicals weaken egg-shells.
So, again, the agrochemicals have to stop.
I think about how a crow matters. Then that crow needs his parents and the community with whom he roosts and forages.
So farmers must never shoot crows.
I think about how a crow matters. Then that crow needs fresh water to drink every now and then.
So the water systems must not be polluted.
I think about how a crow matters. Then that crow needs to breathe oxygen. That means we need to boreal forests and the phytoplankton. The leaves from the trees provide iron to those tiny creatures in the sea, which produce half our oxygen, and feed bigger creatures. The salmon in the sea who swim back up the rivers provide in their decaying bodies the nitrogen the soil needs for plants and trees - which produce the other half of the earth's oxygen.
So we have to protect all the forests and the seas and the salmon.
I think about how a crow matters. Then that crow needs Vitamin D which he gets when sunlight changes the chemical nature of an oil in his feathers which he absorbs when he preens So we can't live under a permanent parasol, so we can't resort to geo-engineering.
So we have to stop the emissions.
I think about how a crow matters. Then that crow needs time to crow and freedom to play and a life that allows him leisure to follow his corvid curiosity.
So we have to live in a world that's not just a battle to survive but where we can all, possibly, thrive.
