There is no doubt that the biggest challenges of any farmer are weeds competing with crops for space, light and nutrients, and insects engulfing harvests like wildfire. Effective pesticides (insecticides, herbicides and fungicides) are therefore miraculous inventions in the eyes of many farmers. They dramatically lower costs by saving time and energy, and most importantly, enable farmers to avoid numerous problems. Humans are known to be visual … Continue reading Unravelling the Secrets of Pesticides
Gardening or urban farming brings elements of sustainability, community, and nature education to the city and into our lives. It creates an environment for people from all walks of life to share the knowledge, skill and joy of growing their own organic produce. At Wildroots Organic, we’ve had great results growing on rooftop farms throughout the city, and teaching urban farming courses at … Continue reading Urban Farming Redefined: 100% Upcycled
Green roofs have once again hit the headlines when the government announced on Wednesday that no one will be prosecuted for the City University of Hong Kong (CityU) roof collapse last year. Safety was the key concern but this incident also prompted questions about the benefit of green roofs. The collapsed CityU roof was essentially a carpet of vegetation that very few people had a … Continue reading Urban rooftop organic farming all-win solution for Hong Kong
Written By Lau Hoi Lung. Translated by Angeline Chan. Soaring property prices, shortage of elderly homes, lack of places for people to enjoy intimate relationships – it seems as though no social problem in Hong Kong is far removed from land issues. The government keeps banging on about limited land supply, lending credence to the saying “Hong Kong is a densely populated city”. Studies on … Continue reading DO WE KNOW OUR SOIL?

Urban farming on rooftops has been gaining traction in cities around the world. Its rise can originally be traced to consumers increasing awareness of carbon emissions that result when our food travels hundreds, if not thousands of miles from the farm to our table. As an experienced urban farmer that grows on the rooftops of commercial buildings such as the Bank of America Tower, and … Continue reading Rooftop Farming
Spraying Roundup herbicide on Roundup Ready crops to kill weeds
In Part 1, the potential of GMOs to fundamentally change the way we grow food was explored. Of course it isn’t all upside and there is risk when transitioning technology from the lab to the field. But as GM technology is just a plant breeding tool, it’s more pressing to look at the context in which it’s being used and to what end. As of now it has been reduced to a bandaid for maintaining an unsustainable system of industrial farming. Because of this, claims that GM crops can benefit humans (by improving the nutritional content) and the environment (by reducing chemical use on farms) have not been realized.
GM crops are by current metrics safe to humans and the environment. They are without a doubt less harmful than pesticides sprayed on open fields that contaminate water supplies and nearby forests. Regardless, there are reasons to be careful, changing the complex dynamics of ecosystems will have consequences. Crops engineered to kill insects could disrupt natural ecosystems. Another concern is the unlikely possibility that the engineered genes may be passed on to other species via cross-pollination. This could spread herbicide resistance on to weeds or unintentionally kill beneficial insects.
The biggest issue is what GM technology is being used in service of – propping up our current system of industrial agriculture. Industrial agriculture involves growing monocultures or miles and miles of a single crop. While maximizing efficiency, it sacrifices the resiliency of a farm in the face of pest and plant diseases by completely destroying the ecology for the purpose of growing one crop. With only a single crop, pest and diseases can spread like wildfire causing great damage. Hence, these fields require extremely potent chemical pesticides to protect them.
