Final answer:
Canada is involved in various international agreements concerning pollution, with the Montreal Protocol and the Kyoto Protocol being significant examples. These agreements have their limitations and enforcement issues but represent crucial steps towards global environmental awareness and action.
Step-by-step explanation:
Canada is a party to several international agreements aimed at addressing pollution issues, including ocean pollution. The most notable of these agreements may include the Montreal Protocol, which, despite primarily focusing on substances that deplete the ozone layer, has contributed to the reduction of emissions that can also affect the oceans. Similarly, Canada is a signatory to the Kyoto Protocol, another significant environmental treaty designed to curb greenhouse gas emissions, indirectly impacting ocean health.
While these agreements demonstrate global intentions to tackle environmental issues, there are concerns about effectiveness due to a lack of enforcement and follow-through by signatory nations. In addition, these agreements do not always address the root causes of environmental degradation, such as unchecked growth and resource exploitation. Despite limitations and controversy over their impact, these treaties represent a collective acknowledgment of environmental issues and, at the very least, serve as a symbol of international concern.
