Greenpeace Discovery: Microplastics Found in 85% of Wild Mammal Faeces in Hong Kong
A recent study conducted by a green group has revealed alarming findings regarding the presence of microplastics in the faeces of wild mammals in Hong Kong. The research, carried out by teams from Hong Kong and Taipei universities in collaboration with Greenpeace, found that 85 per cent of five types of wild mammals living in countryside areas had ingested microplastics.
The study, which collected faecal samples from buffalo, boar, cattle, macaques, and porcupines in seven countryside sites across Hong Kong, uncovered a total of 2,503 pieces of microplastics. Of particular concern was the discovery of polypropylene (PP) debris in the faeces of these mammals, which is commonly used in single-use plastic packaging and takeaway containers.
According to Greenpeace campaigner Leanne Tam, the presence of microplastics in the faeces of wild mammals indicates that plastic pollution has extended beyond urban areas into the countryside. Tam emphasized the urgent need for the government to implement stricter waste reduction policies to address the growing issue of plastic pollution.
The Impact of Microplastics on Wildlife
Microplastics, defined as plastic debris smaller than 5 millimetres in length, were found to be prevalent in the faecal samples collected from wild mammals in Hong Kong. The study identified polyethylene and polypropylene as the main forms of microplastics present in the samples, with polyethylene particles accounting for 47.9 per cent and polypropylene particles making up 36.6 per cent of the total.
Among the wild mammals surveyed, cattle exhibited the highest concentration of microplastics, with a median concentration of 65.5 microplastic particles per gram of dry faeces found in samples collected at Cheung Sha. This alarming discovery highlights the pervasive nature of plastic pollution in the environment and its impact on wildlife.
Challenges in Addressing Plastic Pollution
Despite the implementation of a partial ban on single-use plastics in Hong Kong, challenges remain in reducing plastic waste and mitigating its harmful effects on the ecosystem. The second phase of the ban, which covers additional takeaway containers, lacks a clear timetable for enforcement, leaving room for continued plastic pollution in the city.
Restaurants, in particular, have been slow to adopt eco-friendly alternatives in compliance with the ban on single-use plastics. While major chains have made efforts to switch to non-plastic alternatives, small eateries have been hesitant to make the transition, prolonging the reliance on disposable plastic products.
The Need for Global Action on Plastic Pollution
The findings of the Greenpeace study underscore the urgent need for global action to address the issue of plastic pollution. As more studies reveal the presence of microplastics in natural environments, wildlife, and even human bodies, it has become evident that plastic pollution is a pressing global concern that requires immediate intervention.
Christelle Not, a senior lecturer at the University of Hong Kong’s Department of Earth Sciences, emphasized the importance of a strong Global Plastic Treaty to establish reduction targets and facilitate the formulation of plastic reduction policies by governments worldwide. Not stressed the need for governments and corporations to take a proactive role in developing sustainable solutions to combat plastic pollution.
The Role of Hong Kong in Plastic Consumption
Hong Kong, known for its high per capita plastic consumption, plays a significant role in the global plastic industry. As a financial center for multinational corporations, the city has a responsibility to lead the way in reducing plastic waste and promoting sustainable practices.
Greenpeace has called on the Hong Kong government and corporations to take the lead in developing plastic reduction policies to address the growing issue of plastic pollution. The organization has urged authorities to prioritize the implementation of effective measures to curb the production and consumption of single-use plastics in the city.
Looking Towards a Sustainable Future
As the world grapples with the challenges of plastic pollution, it is crucial for governments, businesses, and individuals to work together towards a sustainable future. By implementing comprehensive waste reduction policies, promoting eco-friendly alternatives, and raising awareness about the impact of plastic pollution on the environment, we can create a cleaner and healthier planet for future generations.
In conclusion, the discovery of microplastics in the faeces of wild mammals in Hong Kong serves as a stark reminder of the pervasive nature of plastic pollution and its detrimental effects on wildlife and the environment. It is imperative for stakeholders at all levels to take proactive measures to address the issue and pave the way for a more sustainable and plastic-free future.
