So plants don't need co2? Plants do well in the cold? Underdeveloped countries are going to dig their way out on the back of alternative energy?
LOL. okay.
The main problem here is you are oversimplifying a very complex issue to bring it down to your level of knowledge instead of making the effort to increase your level of knowledge to truly comprehend the magnitude of the issue. These little "shadow arguments" (bolded above) are no different than the old anti-evolution argument of "well, if humans evolved from monkeys, how come there are still monkeys? did they forget to take their evolution pills? HUR HUR HUR" and highlights a fundamental lack of scientific knowledge on your part.
yes, plants need carbon dioxide for their respiration. but the carbon cycle was working just fine before we (humans) started dumping 40 billion tons (annually) of carbon dioxide on top of it. soil and vegetation are carbon sinks, but like all sinks, there is a limit to how much they can hold. the excess is going into our atmosphere, and trapping heat. your cooling argument is so dumb, i'm not even going to address it here (PM me if you want it). and to address your third statement, undeveloped countries need to focus on establishing sustainable systems of agriculture before anything else and you don't need to burn fossil fuels to do that. its hard to pull your citizens out of economic blight when they are malnourished or otherwise unhealthy and can't contribute to society
beyond that, it's time to look forward. i appreciate everything that fossil fuels have done for society. the industrial revolution enabled us to implement the knowledge of the Enlightenment and build modern society, but the need for alternative energy sources is way past due. staying the course will warm and acidify the oceans to the point where earth can no longer sustain life.
