The big question…Should clean freshwater be considered a renewable resource? In my opinion, of course not! Yes there’s a water cycle that constantly moves water and “replenishes” it, but that doesn’t help if the water that goes up is contaminated. We’re taught that water will virtually never run out, how its a constant in our lives, and that’s true, but to an extent. When that water is full of chemicals and waste, it’s of no use to us anymore. Our planet is less than 3% freshwater, and every day, more of it is being pumped with toxic chemicals from factories, being polluted by our trash and therefore, is becoming more scarce for human and animal life. It needs to be taught that our freshwater is too valuable to just be called unlimited, because that’s translated to “oh well it doesn’t matter if this river gets destroyed, these people will get there water from somewhere else”, when more often than not that’s not the case. For the sake of human beings, freshwater needs to be treated with more care, and be better protected, because unfortunately, if there’s not a change, there wont be any freshwater for any of us.

Hello my fellow wizards and witches, goblins and ghouls, this just in! As we all know (well now you’ll know in case you didn’t) NASA launched Curiosity, the new Mars rover . I just read an article about how there are dark, seasonal streaks found near the Martian equator, which could be a sign of flowing salt water. Scientists say that it could be liquid runoff that melts away during the planets warmer months. Curiosity picked up the dark streaks as they formed in the planets late spring and summer seasons, and then fade during the cooler season. These have been seen before on Martian slopes at mid-latitudes but now the rover is picking them up along the equator. They have yet to detect any signs of liquid water, but the new findings point toward an active water cycle on the Red planet.
From what I’ve been learning in my science class this year, Scientists have reported that Mars could have at one point been an active planet with running water, which is how they’ve explained some of the valleys and crevices found along the planets surface. They say that the force of erosion could have formed these features. I’ve also learned that the atmosphere of Mars is thin and mostly made up of carbon dioxide, much like Earth’s early atmosphere, and with the potential discovery of water, that case seems to grow more true. If Mars is in a state that Earth was in billions of years ago, then maybe it does have the potential to support life.
How cool is this though? To find out that Mars could be a place to live some day? Even just 5 years ago, people probably wouldn’t have even thought it a possibility. But look at all of these reports and new findings. Its all so exciting to hear about! I would definitely like to spend some time up there. This mission has definitely shed some light on the famous Red planet and whether or not it has potential to sustain life.
What do you guys think? Is it possible? Would you like to live on Mars? I’d love to hear what you guys think.
