Lily sun, ‘Climate Change for Sustainable System class’. I chose this theme because of how climate change have changed many species’ habitats. Polar bear, for example, has recently attracted media attention. Videos and pictures of the melting ice and their loss of habitat went viral and brings to the attention of many the no longer fashionable issue of climate change. Especially, I feel it is more than obvious it have changed our climates too; how weather heats up more than previous years and how summers grow perceivably longer in Canada, not as snowy as before.
