You might not have thought about it before, but the chocolate industry is known for being unethical in how it treats people and the planet. More than 2 million children work in cocoa plantations, some of them have even been trafficked. Despite countries signing agreements 20 years ago to reduce child labour in the cocoa industry, numbers have actually increased. The demand for cocoa has increased in recent years, which has led to deforestation. Alter Eco is one brand of ethical chocolate available in Australia - https://altereco.com.au​.
