It is a known fact that we live in the era of global warming, somewhat similar to what scientists say occurred shortly before prehistoric creatures became extinct (some say, not exactly all). Depleting fossil fuel inevitably goes on the rise in lieu of increasing human population & the increasing appetite on power consumption, transportation, and manufacturing etc. contributing greatly towards carbon emission and more global warming.
Some green organizations are discouraging consumption of meats, because the defecation of poultry & cattle leads to increasing accumulation of greenhouse gases. Meanwhile, as global warming takes place, the ice & frosts of the north & south begin to thaw. In doing so, the carbon dioxides from prehistoric carcasses trapped in time (aka premafrost) is released into atmosphere without us seeing/knowing.
The el-nino & the la-nina pendulum affects the climate cycles, bringing about freak weathers & snap hurricanes, typhoons, and for some reasons increased frequencies of submarine earthquakes, triggering tsunamis occasionally etc.
When freak weather takes place, 1 thing is most certain; crops are destroyed. Shortages of crops in some countries will eventually lead to spiked prices on food commodities. Well, all hope isn’t lost.
Globalization & saturation of human populace in major cities is a social norm across continents, in the wake of masses seeking employment to sustain. There in evolves a problem where the agricultural lands are pushed to the far corners of the territories, resulting in increased costs to produce, pack, & deliver to the shelves in the cities.
Besides, concrete jungles without elements of natural life source in the likes of plants to match (ideally, outnumber) the ratio of human population can actually be quite depressing. Not to mention, the less fresh air as well.
Given the technological advancements & innovative materials applicable for buildings, horticulture can actually become the next big thing in urban settings.
As we all know, agriculture requires vast plains & the correct conditions for healthy crops & harvest. Organic or non-organic, they are susceptible to pest invasion & climate changes, affecting the crops & harvests.
Meanwhile, in the context of horticulture, stacking is possible if given limitations of land. The higher the building is the more crops can be grown. High ceilings, full windows (greenhouse effect), maximize filtered air flow (minimize contamination), either hydroponics/ sprinkler (irrigation) system, and if budget allows… night lighting for accelerated growth to shorten yield cycles.
Looking at the bigger picture, if each city is equipped with proportional sustenance, the costs to feed people can be better managed against climate changing trends. While the supply chain is also shortened and optimized, the probability of cost escalation for food can also be reversed.
At the end of the day, there are tangible & intangible incentives to consider revamping urban/ town planning, if the objective is to see allow our descendants enjoy & see the next century.
