How to Balance Our Long-term and Short-term Goals in the Climate Crisis

We must first define what our long-term and short-term goals are, because they vary from person to person. To be universal, the definitions of these goals that I refer to focus on the most important things. The long-term goal is to keep humanity alive as long as possible, and the short-term goal is to meet everyone's basic needs, such as food, shelter, medicine, etc.
As long as there are sufficient resources to meet our basic needs, we can continue to pursue the long-term goal, but if the short-term goal conflicts with the long-term goal, how do we balance them? Take global warming, for example. Our long-term goal requires billions of people to drastically reduce their carbon emissions by greatly reducing their consumption of fossil fuels, when in fact fossil fuels provide most of their basic needs. It seems impossible to achieve the long-term goal because few people will care about the future of humanity if they cannot feed their families. Should we then hopelessly cause the suffering of billions of people in the coming decades and possibly make our own species extinct in the coming centuries by continuing business as usual? Certainly not!
Since we cannot sacrifice our basic needs for humanity's future, everything we do will shorten or widen the distance between the long-term and short-term goals. When widening is inevitable, shortening is necessary to bridge the distance. In other words, anything that helps us achieve our short- and long-term goals must be prioritized and accelerated. For example, scientific progress is useful both to meet our basic needs and to save everyone’s future. I believe that scientific and technological progress can be accelerated by making geniuses all over the world.
