Among the problems facing the world today actually support population growth. Population growth is actually a serious problem not only because more people are born every year, but also because the average life span also increases. These two factors are an important reason why we must find a better and more lasting way to grow the food we need.
Traditional family farming is quickly becoming a part of the past. They are replaced by agricultural companies. This has various impacts on food production. Because they are agricultural companies, profit is the driving force and the desire to grow certain plants is lost. This can result in many farms avoiding crops which are the staple food for many people because the cost of producing them compared to the prices they order on the market is higher than other crops. The proven way that people have tried to overcome this problem is to grow staple plants in their own gardens. Many rural families maintain gardens that can help provide the vegetables they need. It is important for us to start planting some of our own food, however, more and more places have grown to be very urban and the important space for a park is very limited in these areas. Most people live in apartments and do not have access to fertile land. A number of big cities, now called big cities, are trying to develop a method of growing vegetables themselves to help keep food costs lower for their citizens. Foods that might grow in the city might avoid the high transportation costs associated with importing exactly the same products from surrounding rural areas or other countries. In addition, vegetables will become fresher. The main challenge facing these cities is finding suitable space for growing vegetables.
One of the better known approaches is to always need a hydroponic growing system. This type of arrangement can be very effective in a very urbanized area. Most of these hydroponic farms are erected on the roofs of tall buildings to take advantage of easy access to sunlight. Simply put, hydroponic systems grow plants in nutrient-rich solutions that must circulate through the root system. The solution is likely to be found in plastic structures even though glass and metal structures have also been used. There are thin sheets of styrofoam and also similar substances that protect the roots of plants in solution while the leaves and stems remain on top of them.
