First things first, PLEASE!! First thing is that people have been preaching doom and gloom of the planet due to overpopulation and 'pollution' since Noah landed!! So take a minute to reflect on what is really happening in your classes. That would be an agenda that is very much debatable. World Population? Everyone on this planet could live inside the boundaries of Texas, and not be crowded! That is a FACT, not an opinion or talking point. Water shortage?? Really? 3/4s of the planet is WATER!! Oh, so they teach you we are running out of 'good water'? You can make a solar disstillation system that will clean up any 'dirty water' with items you will find in your kitchen and produce all the fresh, and REALLY pure drinking water you can use. So, before you panic, get so KNOWLEDGE, that is the facts and not the politically correct dogma.
xD To be honest I have no clue what to expect.
Like said, both sides are very debatable. And yes 3/4s of the planet is water. Of that 75% of Earth's water, 96% of that water is of the ocean and 2% is freshwater.
Unfortunately of that 2% of fresh water, 68% of that fresh water is found in glaciers and ice caps and of that same 2% of fresh water only 30% comes from ground water.
And yes we can desalinate ocean water and make water wells to get that ground water and even use aquifers to get more water, but just like how we drill into the ground to pump oil we've taken so much. Just like how gas prices rise and drop, the amount of oil we have left in the ground might be less than what we think. Same as water wells. We pump so much and from so many places, can we really say we're taking just the minimum?
It's debatable. And yes, the whole planet can live inside the boundaries of Texas, but really can we really? We can't because we're selfish. The majority of people do things for self benefit. We wouldn't even want to fit the 300 billion people in the US into Texas. So to try to fit everyone on Earth, is quite questionable.
Most people can't even live comfortably with 15 people living in a 2 bedroom duplex and 1 bathroom. I've been there. It's not fun.
Thing is, although it seems easy to fix, like making a solar distillation system go ahead. But not everyone can do that, but if you can do it.
But even then, how many people would want to drink distilled water all the time? Distilled water pretty much has no minerals in it which then increases the acidity in the body.
and then someone like me might argue to take vitamins and other stuff that'd make up for that loss of minerals... but It's just an endless debate.
Sorry, I might've just totally sounded like a biased A-hole... xD But it is genuinely me acknowledging the use of water and whether or not there really is enough if we're not sustainable.
Whooooooo. Sorry that was mucho. xD
