Recently some areas in Africa which had food insecurity started getting an influx of Prickly Pear Cactus, and at first they complained about this invasive species of cactus, but then they learned that you can eat the cactus, and that you can have cactus with scrambled eggs, salsa, and tortillas, and you can make candy out of the cactus, etc. The Mexicans have been eating the Prickly Pear Cactus for a long time, and they sell it at the Mexican markets here in Anaheim. So, that is a step in the right direction, the cactus is not invasive, it is FOOD.
And we need to send food from California to China, etc, and we need to support and teach the farmers in India, and we can all work together to make sure that the world has enough food, and we have UNICEF which feeds the children, etc.
Sending Winter Vegetables from Arizona to New York and Chicago and Detroit, and Cincinnati, etc, is a step in the right direction.
Food, and running water, are important issues, then also is helping to elevate society by having libraries and schools.
And on how many people the world can hold? I heard that you can fit the whole population of the world in Texas alone with room to spare. We have plenty of room, we just need food, peace, teamwork, schools, libraries, and we need to train teachers, and doctors, and scientists, etc. And people need housing, etc.
Salute,
