Influenced by anthropogenic climate change, the complex nature of the human-animal interface is continuously threatened and zoonotic diseases are rising. Domestic animals themselves are reservoirs of zoonotic diseases (e.g. Avian influenza) and poor livestock practices endangers both humans and animals. Encroachment of human settlements increase the interactions between humans and wildlife species which helps facilitate the spread of zoonotic diseases. Atmospheric carbon dioxide in the environment also influences the animal-plant interface with invasive species dynamics fluctuating (Naicker 2019). A One Health approach to preventative human and animal health surveillance can assist in more rapid detection of disease with feedback at a local level and information sharing on a global scale (Cunningham, Andrew A et al 2017).
A research scientist at the CSIRO, Kevin Hennessy, claims “Australia will warm faster than the rest of the world” (Milman 2015). The country should already be alarmed and be preparing to work towards substantial reductions in global greenhouse gases. A healthy and steady climate underpins life on earth. Embracing a One health perspective will contribute to a changing and sustainable planet. Increasing public awareness in Australia regarding the long-term consequences of human actions will not only alert many, but also assist in the promotion of undertaking healthy and green practices. Provision of concrete goals with the assistance of the government, for both current and upcoming climate efforts, will provide a motive for the population to work up to. The average Australian household is accountable for a large 7 tonnes of greenhouse gases emissions per annum. Advertisements regarding the use of energy efficient options such as insulation of solar panels, will assist in reducing emissions per household. The country’s transport sector is responsible for 16% of Australia’s overall gas emissions and ranks ninth-highest transport polluter. Choosing active transport, hence sustainable mobility like walking or cycling will help lower carbon footprint (Council 2018). Although countries like China and India have much lower rates of car possession compared to countries in the west including Australia, they will eventually emulate western consumers. Consequently, Australia setting an example and following green gestures will prove to be significant worldwide and leave a positive impact for the long run.
Moving to a more sustainable path will require cooperation on a national level and Australia should display global leadership with regards to reducing global greenhouse gas emissions. Climate change is already putting strain on human, animal and environmental health. Australia’s biodiversity and ecosystems is one of the most renowned yet extremely fragile to the exposure to climate change. Unless green gestures are promoted and practiced, impacts of anthropogenic climate change will continue to proliferate which many ecosystems can’t adapt to. Implementing a national strategy which incorporates the collaboration from multiple sectors, will assist in unravelling climate related crises, making the One Health vision come to life. With every delay, the consequences the planet will face will only become more severe. Safeguarding the environment must be of uttermost priority, be it a developing country or Australia.
