Potentially Habitable Exoplanets - An Easy Way Out?

I’m sure you have all heard of the 2014 Christopher Nolan film Interstellar. If you can’t remember, the general plot of the movie centers around humanity’s demise; almost all of the crops on Earth are failing, therefore Earth is no longer suitable to sustain human life. This then calls for mankind to search for other habitable planets where humanity can escape to and prosper. This movie was all the rage in 2014, and justly so. Christopher Nolan gave us a film that, although being sci-fi, actually broached a realistic topic that needs to be considered: How long does humankind have on this Earth before we are forced to retreat to some other planet that is better suited to house humanity?


t’s far off into the future, but it’s no secret; with the way we are treating our Earth, the scramble to search for another habitable planet is crucial. In February 2017, astronomers discovered 7 potentially habitable exoplanets (a planet that orbits a star outside of our solar system), and these planets are nicknamed Earth’s Seven Sisters, for they have liquid and mass compositions similar to our blue and green planet. Oliver Guyon, a planet-hunting affiliate at NASA’s Jet Propulsion Laboratory, called these discoveries ‘game changing’ and extremely exciting not only for science but also for humankind. The general public is excited as well. The reaction from thousands of people was not “what’s out there?” but instead “when can we leave?”.

There’s no denying that over the recent years, we’ve treated our Earth badly. However, I believe that escaping from this planet will not provide humankind with any solutions, although it may appear that way. Sam Kriss put it beautifully when he said that exploring the galaxy doesn’t give us solutions, instead it just gives more room for Earth’s problem to expand. I agree with Sam.

With World Environment Day coming up on June 5th, it’s important to sit back and reflect on how much we owe to our little planet called Earth. Earth is, to put it simply, our one and only home, however it needs our help if we ever wish to prosper here far into the future. This is my encouragement to all those who are reading to start thinking about how to live a more sustainable and green life, even in the smallest of ways. There are many great articles on how to go green, and it only takes a couple of minutes to learn more about our Earth and how to protect it.

It’s time to look out for the planet that looks after us!
