so im studying for my geography 2090: space exploration midterm.
and i never knew this.. but ive just discovered that there are over 8,000 man made satellites (which are functioning) orbiting our Earth. so meaning there are PLENTY more which aren't functioning and basically.. garbage satellites just orbiting our earth.
so after watching Wall-E, i guess that it was pretty accurate when they showed the spacecraft leaving Earth, and Wall-E was attached to the edge of it. i thought it was a pretty funny joke when sputnik was flying off of Wall-E's head after they shot thru the crazy layer of satellites when exiting the Earth's atmosphere. haha... but i never realized just how much junk we have up there. in a way, i knew we couldnt rely on like a satellite or 2 for all our weather, GPS systems, cell phones, TV, government stuff, etc. but i never would have guessed that there's over 8,000 up there. wow...
ever since i started taking geography seriously (as in i wanted to major in it), ive realized more and more how much we're abusing the planet.
and watching all these movies which take place in the future are all quite accurate to some degree. like I Am Legend. so many scientists coming up with different things in labs now, something is bound to occur and wipe out a good chunk of the earth's population. look at SARS for instance. so it didnt wipe out THAT many ppl, but it still stirred chaos and panic around the world. but funny how it took something like that to make us unify as a planet to stop it. the world health organization (WHO). gg UN. then after its stopped, we all go back to our racism and stuff. *sigh*.... like yeah.. i mean, our current generation right now (aka the ppl who are alive) will be okay. we've got enough resources to last us our lifetime. but at the rate our population is growing, our resources are definitely not enough. we're closing in on reaching the 8billion point. its insane. when my parents were born, it was at like the 3billion point or so. we've almost tripled in like 50 years.
and if you think technology will reach a point where we can leave earth and migrate to some other planet, nope. its not happening. or at least there hasnt been ANY discoveries of a suitable living place. so even if we assume we find a suitable location soon, there's still plenty to do before we can migrate there. building enough space crafts to transport everyone there will take eons... thast if Earth has enough materials left! aka Earth is screwed if we keep this up!
haha.. can't believe i've gone all "hug a tree". =P
