Want to know more about global warming and what you can do? Dr Herman Friedman is regarded as a pioneer expert in this field, and he will give a speech in Grayson Hall next Friday. Before becoming an expert in this field, Friedman studied environmental science in three world-renowned universities, and he also traveled around the world to observe the current situation of climate change.

The new book signed by him was just published last month and will be listed after his speech.
