Final answer:
Preserving national parks is the action that best represents protecting and enjoying the heritage and environment in Canada, as it supports biodiversity conservation and provides spaces for people to experience nature.
Step-by-step explanation:
Protecting and enjoying the heritage and environment in Canada can be represented by several actions, but the answer that most accurately reflects this commitment is preserving national parks. Option D aligns with the goal of conservation of biodiversity, which emphasizes the need to maintain protected areas to ensure that ecosystems and the species within them, including humans, can thrive. These national parks serve as habitats for indigenous species, which helps in protecting biodiversity, and also provide a space for people to connect with and appreciate the natural environment. In contrast, options such as embracing urbanization or promoting industrialization may pose threats to biodiversity, whereas introducing invasive species, as mentioned in the information provided, would decrease biodiversity and ecosystem productivity.
