Climate Change: Why aren't more people concerned about it?

Here is my own,give me one problem in this world where the "free market" has come to the rescue and solved it.

The markets cannot expand exponentially, the resources are limited, so there is no market solution to the problem of providing food for an expanding population once those resource limits are reached.

At present, the US livestock population consumes more than 7 times as much grain as is consumed directly by the entire American population (11). The amount of grains fed to US livestock is sufficient to feed about 840 million people who follow a plant-based diet (7). From the US livestock population, a total of about 8 million tons (metric) of animal protein is produced annually. With an average distribution assumed, this protein is sufficient to supply about 77 g of animal protein daily per American. With the addition of about 35 g of available plant protein consumed per person, a total of 112 g of protein is available per capita in the United States per day (11). Note that the recommended daily allowance (RDA) for adults per day is 56 g of protein from a mixed diet. Therefore, based on these data, each American consumes about twice the RDA for protein. Americans on average are eating too much and are consuming about 1000 kcal in excess per day per capita (12, 13). The protein consumed per day on the lactoovovegetarian diet is 89 g per day. This is significantly lower than the 112 g for the meat-based diet but still much higher than the RDA of 56 g per day.

It would likely go to illegals as much if our social services do. Perhaps we should enforce our border and not allow a massive overpopulation of the US. Perhaps we should scrap NASA and any plans for the moon. Same for space tourism
