I worry about the future, not that I would likely live to see the worst effects in my lifetime, but my children might — and if they have children, my grandchildren will.
Already, I believe that our climate has irrevocably altered. Things I enjoy like chocolate, coffee, vanilla… those may disappear in a couple decades, because the species that produce these treats are not likely to be able to adapt quickly enough to changing climate patterns. In our own part of the world, for several of the last ten years we have MISSED the “pre-spring” summer. When I was in college, we could count on getting a couple of weeks of near-summer weather in March before the rains returned. It would gradually warm up, and although we could expect rain as late as early July, we knew that mid-July to mid-September would be dry. So did the plants and animals, and growth cycles adapted to the peculiarities of our rainy season.
Here are two articles that I believe are based on science, that describe what has happened in the past when certain parameters are met.
I do not necessarily think this will happen, but I think the possibility exists. What can I do about it? I am continuing to attempt to live lightly, with fewer purchases in general; trying to take fewer trips by cars with combustion engines; trying to eat locally when possible (with my allergies though I must supplement with additional food sources from far away…); using up and wearing out, recycling, upcycling, and other ways to prevent materials that have finished their first use from entering the waste stream.
I try to teach my children (my own children as well as my students) to be thoughtful, aware, and safe. I know that a worst-case scenario will be devastating world-wide; already such awful conditions exist in many nations near the equator, in areas that suffer drought, famine, and weather disasters on a regular basis. Cholera in Yemen. Fires in Europe and North America. Hurricanes on the East Coast and … this could be a long list. Long story short? Things are changing. They are changing quickly and the old ways of dealing with limited resources won’t work.
It’s not just the economic picture, which will definitely have to adjust; with many on the losing end finishing in poverty. It is the ecosystems that will suffer the most: animals in the wild, plants, the oceans. As each species adapts or, more likely succumbs, to the changes, our world will never be the same. Already, some changes are inalterable. They may not all be bad in the long run, but we will need to change to keep up with them.
For me, step one is to be aware. The second is to address in my own life that which I can without withdrawing from society and waiting to die. The third is to contact my elected officials, friends, others who may care; yes, I vote! But I am ill-equipped with my allergies to participate in demonstrations or sit-ins, my professional training and avocational interests do not equip me to invent a device or material that can restore our atmosphere and biosphere. For other steps, I must hope there are people who will fill in.
Am I worried? Yes. Do I lose sleep over this? Not often — Not sure what the benefit would be of that! But I am doing what I can, to the best of my ability. And I still hope, because my children and my students are worth it. I do what I can.
