As the world's population grows, so does the food needed for humans, but because of limited land and the different climatic environments that lead to different aggregates of food per region, areas that are unable to grow food can rely only on food imports to solve people's food problems, while some poor countries have inadequate access to food and food crises, leading to a range of problems。
As the global climate changes, food production is seen to change. Stabilizing food production requires increasing science and technology and finding new ways of nurturing, perhaps in order to solve the problems of the world's population. In fact, many parts of the planet are uninhabited and desolate areas, and these marginal lands are not being used by humans and have not yet been developed because of the infertile nature of the land, which prevents them from growing food. Without enough land to grow food, a new food crisis could be triggered in a long time, so that the plan to plant food in space appeared quietly in the minds of people and was being practiced by many。
Scientists discover that when food is bred from space, when it is brought back to the earth for cultivation, its genes change more or less, and some are able to grow strong even under harsh conditions, which can contribute significantly to total food production. Growing food in space is not really unfeasible, and it is only necessary to build a huge space greenhouse in which many vegetables and fruits are grown, so that the food crisis can be alleviated or addressed。
It is, however, quite difficult to construct a space greenhouse, which, after all, will cost a great deal and, together with later maintenance and the harvesting, transportation, etc. Of vegetables and fruits, will require a great deal of human, financial and material resources and will not guarantee the safety of every transport. Given the problems of space greenhouses, what else can we grow more food? As a result, many have suggested growing food on other planets and supplying the planet with constant supplies, perhaps another solution to the food crisis。
The original planet was the moon and mars, but according to current research, it is impossible to plant vegetable fruit on the moon, because china’s self-built typhus 4 tried to cultivate plants on the moon, but it was frozen to death on the second day after the plant sprouts. Thus, growing vegetables and fruits on the moon is not realistic. And mars, where research is still on the surface, where there is little understanding of the soil and where there is no seed breeding experiment, is more difficult to judge。
But it is also impossible to speculate in the first place about growing vegetables and fruits on mars, because plants can't grow because of high temperatures and poor weather conditions. Faced with this dilemma, many have suggested that building a base on the moon or mars that would have the effect of a greenhouse, perhaps yielding vegetable cultivation, and that growing vegetables would not necessarily require soil, since hydroponic crops are already widely used and even the technology of sea water to grow rice and vegetables, would it not be feasible to plant them on mars or the moon
In theory, such an approach is feasible, but the process of achieving it is difficult and costly than one could imagine, so the cultivation of vegetables and fruits in outer space is not yet possible, at least in terms of quantity. While we are all aware that people produce food that does not satisfy all human beings, there are even poor areas that feed on soil, which is diluted and then constantly filtered into mudcakes。
So in everyday life, we have to cherish food, love food, and action empty。
