Hello everyone. This is Bolun Xie. You can also call me Chris. It is a great pleasure to meet you all at CoSphere. I am a senior student majoring in environmental science. Moreover, I choose Sustainability Science as my area of concentration. To keep our world in sustainable development, this concentration can give me more information about how to do and protect our planet. ENVR430 is a course that describes sustainability in various ecological dimensions. If you are interested in the environment and sustainability, join the Cosphere and follow #UnleashValues with us! I can not wait to use the information and the knowledge we learn in the future to help save our world!
