Heavy metal contamination is a problem
The most serious drawback of urban gardens is that of heavy metal pollution in cities, generated especially by car engines, more specifically diesel engines, which are estimated to be killing 15.000 people each year in Spain.
Heavy metals such as lead are deposited in urban home gardens and then ingested, which can cause a significant health problem. Other heavy metals that we are at risk of ingesting are chromium, mercury and cadmium.
If we want to have a healthy urban garden, it is best to have it closed, in a small greenhouse or far from the city. But this is not possible in many cases, so it is advisable to take extreme precautionary measures and wash the food very well before eating it.
Higher water consumption
Today, what is grown in urban gardens are essentially irrigated plants. Although in the past we only planted aromatic or medicinal plants. These plants require a constant supply of water, which can cause spending on this resource to skyrocket. Which would be disastrous, not only for our pockets, but also for the environment. In this sense, it is better to bet on hydroponic crops.
waste risk
If we do not adapt what we grow to what we consume, we run the risk of generating a great deal of waste. Produce to throw away. On the other hand, we must be quite constant with the care of our urban gardens since, if we are not, we can lose what is harvested, which is another important form of waste.
insect attraction
Urban gardens can be very attractive to some stinging insects such as wasps. It is not a serious problem, but if we have children at home or people allergic to the bite of certain insects, it can become so. In this sense, it is interesting to use mosquito nets and tools to prevent insects from gaining access to the plantations.
The most serious problem in this aspect is represented by mosquitoes. Seedbeds with water and containers with water and certain organic waste are very attractive to the tiger mosquito, the main carrier of diseases.
Conclusions
Just because a crop is natural doesn't mean it's safer or healthier. If you want to place an urban garden in the city, we recommend that you do so with aromatic plants and other types of crops that are not intended for direct consumption.
The WHO and different experts in the sector have already established conversations to raise awareness about the risks and aspects of urban gardens that must be controlled so that they do not pose a risk to our health. You add up?
