Population control MUST be part of climate change/sustainable policies

Climate change is a real and threatening danger. Uptake in sever weather, natural disasters, stagnant food production, dwindling water resources, melting polar caps and glaciers, and extinction of animals, insects, coral that depend on specific temperatures to survive. It is a danger that has been scientifically linked to excessive carbon and greenhouse gases in the atmosphere trapping heat and UV rays from the sun that should be reflected back into space and the heat and carbon from our own industrial complexes trapped under the layer they created.. Critics say that the Earth has experience climate change before during times that modern humans were not even alive and therefor human activity can not be causing climate change, even if it exists. But look at what CAUSES climate change. Excessive carbon and greenhouse gases in the atmosphere trapping heat and UV rays. In the past this was created by volcanic activity, run away continent wide wildfires, and a massive meter impact throwing millions of tons of dust, dirts, smoke/carbon, and greenhouses gases into the air, blocking out the sun to where very little light reach the Earths surface to heat it and causing an ice age. Critics say that if we ARE having climate change why are we not getting colder then ? Because once those events happened, they ended. Once all the trees were burned down, there was nothing to burn, once the volcano released all its pressure and stopped erupting, no more heat and carbon/greenhouse gases that trap heat were being produced. There was only one big meteor, one big explosion that created a layer of carbon and greenhouse gases that enveloped the whole world.. Imagine that layer is a house. All the windows are locked closed, all exterior doors locked shut, and the heater is set at 90degrees and the stove is on medium heat, going for hours on end. There maybe a few leaks here and there but all in all the house soon becomes unbearably hot and stuffy. You turn off the stove and heater so it won't get any hotter and eventually the house cools because of the leaks. May take a very long time but it happens. Now imagine instead of turning off the heater and stove, you leave them as they are or ,being generous, turn them down a bit BUT not a lot and they are still going strong for hours and hours. Imagine you add a roommate that has their own heater and stove going as well, and then another, and then another, so on and so forth. The house becomes unbearably hot even faster with each new addition. Even if all of you turned down the heaters and stoves down to the BARE MINIMUM NEEDED TO SURVIVE, with all of the trapped heat from before, the added people adding their own heat/emissions on top of that, the heat will not dissipate before you all die of heat stroke, starvation cause no food plants can grow in such hot and water parched conditions, or oxygen deprivation cause their are no plants to turn the heat and exhale ( carbon emissions) into breathable air. Humans are highly adaptable and we could probably hold out for a few generations after the collapse of the earths ecosystem but eventually we to would have to adapt or perish. So why wait till a bottom of the barrel crisis before enforcing laws and society norms that control our population rise ALONG with strategies to curb and reduce our resource guzzling ways ? It has been scientifically tested and projected by many scientists that Earth has a maximum carrying capacity of 9 billion to 10 billion people. Right now we are a bit above 7 billion and grow by about a 200,000 a year. One such scientist, the eminent Harvard University sociobiologist Edward O. Wilson, bases his estimate on calculations of the Earth's available resources. As Wilson pointed out in his book "The Future of Life" (Knopf, 2002), "The constraints of the biosphere are fixed." According to population biologist Joel Cohen of Columbia University, other environmental factors that limit the Earth's carrying capacity are the nitrogen cycle, available quantities of phosphorus, atmospheric carbon concentrations, and many other systems work together, all interwoven to create and sustain life on Earth. Aside from the limited availability of freshwater, there are indeed constraints on the amount of food that Earth can produce. Even in the case of maximum efficiency, in which all the grains grown are dedicated to feeding humans (instead of livestock, which is an inefficient way to convert plant energy into food energy), there's still a limit to how far the available quantities can stretch. "If everyone agreed to become vegetarian, leaving little or nothing for livestock, the present 1.4 billion hectares of arable land (3.5 billion acres) would support about 10 billion people," Wilson wrote. The 3.5 billion acres would produce approximately 2 billion tons of grains annually UNDER OPTIMUM SUSTAINED CLIMATE AND WEATHER, something that is slowly becoming rare around the world. But pushing that point aside, thats enough to feed 10 billion vegetarians, but would only feed 2.5 billion omnivores under US standards of consumption, because so much vegetation is dedicated to livestock and poultry in the United States. So 10 billion people is the uppermost population limit where food is concerned if EVERYONE became vegetarians. But because it's extremely unlikely that everyone will agree to stop eating meat, so the maximum carrying capacity of the Earth based on food resources will most likely fall short of 10 billion and be more around 8 or 9 billion. OH wait .... We are already almost there ! and the world population is expected to hit 8 billion by 2024. Our bulging population not only threatens us but every living thing on planet Earth. Population control methods MUST be part of ALL climate change, sustainable resource, and green funding policies. A grain of sand my seem tiny but added together they become a huge desert that can swallow us whole.
