I'll also add there are important things to discuss about humankind's impact to the environment besides climate change-- overhunting and overfishing as well as pollution and usage of pesticides not only adversely impact the environment, but our health too.
We were discussing the impact of overfishing in our subforum earlier

Clover, a former environment editor of the Daily Telegraph and now a columnist on the Sunday Times, describes how modern fishing is destroying ocean ecosystems. He concludes that current worldwide fish consumption is unsustainable.[2] The book provides details about overfishing in many of the world's critical ocean habitats, such as the New England fishing grounds, west African coastlines, the European North Atlantic fishing grounds, and the ocean around Japan.[3] The book concludes with suggestions on how the nations of the world could engage in sustainable ocean fishing.[3]

The journal Science published a four-year study in November 2006, which predicted that, at prevailing trends, the world would run out of wild-caught seafood in 2048. The scientists stated that the decline was a result of overfishing, pollution and other environmental factors that were reducing the population of fisheries at the same time as their ecosystems were being annihilated. Many countries, such as Tonga, the United States, Australia and Bahamas, and international management bodies have taken steps to appropriately manage marine resources.[6][7]

Through the 1990s, Pauly’s work centered on the effects of overfishing. The author of several books and more than 500 scientific papers, Pauly is a prolific writer and communicator. He developed the concept of shifting baselines in 1995 and authored the seminal paper, Fishing down marine food webs, in 1998.[7] For working to protect the environment, he earned a place in the "Scientific American 50" in 2003, the same year The New York Times labeled him an "iconoclast". Pauly won the International Cosmos Prize in 2005, the Volvo Environment Prize in 2006, the Excellence in Ecology Prize and Ted Danson Ocean Hero Award in 2007, the Ramon Margalef Prize in Ecology and Environmental Sciences in 2008,[8] and the Nierenberg Prize for Science in the Public Interest from the Scripps Institution of Oceanography in 2012. In 2015, Pauly received the Peter Benchley Ocean Award for Excellence in Science.[9] In 2016, he was honored in Paris with the Albert Ier Grand Medal in the Science category.[10] In 2017, he received, together with Dirk Zeller as part of the Sea Around Us leading team, the Ocean Award in the Science category.[11]
Also in 2017 and specifically on French National Day, he was named Chevalier de la Légion D’Honneur.[12]
Pauly has written several books, including Darwin's Fishes[13] (Cambridge University Press), Five Easy Pieces: How Fishing Impacts Marine Ecosystems (Island Press) and Gasping Fish and Panting Squids: Oxygen, Temperature and the Growth of Water-Breathing Animals.

To date, he frequently expresses opinions about public policy. Specifically, he argues that governments should abolish subsidies to fishing fleets[14] and establish marine reserves. He is a member of the Board of Oceana. In a 2009 article written for The New Republic, Pauly compares today's fisheries to a global Ponzi scheme.[15]
