Seeing as this is a different topic, I'll post on everything.
Because as a whole, we are always looking for what will hurt us. Humans just can't think on the sunny side...
-- For the ones that have the power to think, in the world -- They want to keep that power. Therefore, they come with a crisis. And its likely, as its been stated that someone uses that crisis to make money (IE : Sell green house products en masse) , a better example would be that the sub-group of environment besides c02 emissions caring, where people just care about what'd happen to the animalz.
Also, Humans are the fastest changing species on the planet if you categorize them such that they are characterized by their habits of how they make/do things
Lastly, Many countires are NOT experiencing booms in population, are you kidding me?
We've got a large majority of Europe and Japan, along with Russia experiences large '
opulation' issues. The problem in Europe is that the labor force is dying, as it dies, the immigration quota increases -- They fear more 'brown people' invading their nation -- Europe has seen different people, but they've fought among themselves until the last century. It changes things.
If you look at China, you'll see the population has stabilized, its not going far.
If you look at
India, that place is stuffed.
Pakistan has half the population of USA stuffed into a size the third of Texas
Bangladesh is just about the same, stuffed into a smaller size
South East asia is jamm packed.
Africa is slowly growing in population, most of which will also -- be in poverty (at least, in major areas)
*All of these countries are gaining people, fast.
Population crisis exists in the world, and its a problem. It just hasn't gotten to the USA, -- Predicted to only increase about 200 Million-100Million in the next 100 Years
