There is loads we can do. Living sustainably and working on community gardens, orchards and working toward growing food and storing water for yourself is a great thing to do to become environmentally friendly and to prepare for possible food shortages.
I have a vegetable garden, allotment plot and engage in community gardens and orchards around my area, and last years 40°c weather scorched many plants and much of my crop was small or died as I couldn't keep the ground wet enough. It was worrying.
I am behind this year because its so wet and cold I haven't had a chance to go out and get things ready.
Things have been stable for many years but a couple of years ago we had a really wet may and many of my seedlings drowned when planted. It was way too saturated for them.
This kind of thing is happening really often. People who are usually friends or indifferent were fighting over water for their plants last year! I mean, we all wanted to water our plants more but water was running low and a couple of people were taking the milk.
It felt like a little taster of what would happen should resources that we usually take for granted become less available.
technically the UK is in drought mode, our reservoirs aren't filling back up after our hot summer, rainfall has dropped.
There are way too many things to worry about but my family are still eating apples and preserved/ frozen fruit and veg from last year.
Apples, carrots (in sand), pumpkins and squash store for months and months. I obviously enjoy gardening, but knowing what I can grow and eat and store all year really helps my anxiety around climate change. I know loads of people I can talk about this stuff with, some men have been gardening since before I was born and the general census is this - Things are changing and people are having to adapt or go without.
