Mabroko; I agree with some of your points, but I was addressing his statement regarding fossil fuels killing the planet. Of the assorted topics you brought up, one of them (climate) has a possible pipeline/fossil fuels link, however specious it might be. Desertification, erosion and deforestation are directly tied to one another and have no bearing on fossil fuels (FF). Over fishing and ocean pollution, ditto. 

Re the potential for FF to potentially aggravate the deforestation, I invite you to check out a NASA study showing that the Earth's green cover has more than doubled in the past couple of decades. This is attributed to the life-giving properties of CO2. See https://www.nasa.gov/feature/goddard/2016/carbon-dioxide-fertilization-greening-earth
