If the problem of rice is a problem of food shortages, then you can see in some countries that try to plant rice using small land. The source of problems like this is because humans are too lazy and rely too much on things that are easier to use. Although the land owned is usually more productive and can be used to plant some basic needs to support food problems.
Best solution:
1. Start loving the agricultural sector
2. Planting food for your own needs
3. Take advantage of small land to be more productive, by planting some food needs on a family scale.
believe with this new information about the crypto space can our climate change system be put together where there will be high rate of food shortages in the global world as a new beginner I want to know we can fix this things I mentioned.
I do not understand the relationship of cryptocurrency with the climate change you mean, can you explain in detail and what type of links you mean. Climate change and the relationship of food sources may have an interconnected level of influence, but if the relationship with cryptocurrency is completely irrelevant, although maybe what you mean is Bitcoin mining.
