Earth After Humans

‘Save the planet!’ We are constantly reminded of this, but do we really listen? Well maybe we should!  Mind Warehouse created a time-lapse video with predicted stages of what would happen to our world and it’s inhabiters, starting with a few hours after we disappear to 300 million years later.

So lets begin! The theory predicts that after several hours, the lights around the world would begin to go out, as power stations run on fossil fuel and WE are the ones to control them. This continues 48 hours later with nuclear power plants switching to safety mode due to the drastic decrease in energy consumption, and power cuts in regions that aren’t supplied by hydroelectric power stations.

3 days later, this is where things become more chaotic! The tubes and metros will supposedly become flooded as humans won’t be powering the pumps protecting them. After 10 days, domestic animals locked indoors and livestock will start to die out from starvation and dehydration. Survival of the fittest will set in with larger dog breeds forming packs, and hunting the smaller breeds.. say bye-bye to the chihuahua’s and tea-cup terriers!

A month after human extinction, circumstances deteriorate even more, with explosions occurring from evaporated cooling water in power stations. Radioactivity eventually kills the rest of the animals, but don’t underestimate her! Because this is where planet earth begins to fight back and recover.

One year later, strange stars will fall to earth, as humans over the years placed thousands of objects into earth’s orbit, along with the highest satellites a few more years later. 25 years later, earth begins to flourish without us, as squares and sidewalks turn into areas of vegetation, cities like Dubai and Las Vegas will be covered in sand, and overall the air will be much cleaner without the toxicity of human inhabitants.

Hundreds of years later, man-made constructions will continue to erode and collapse, with nature taking over as vast swamps reappear, and bird and animal species returning to their homes which were unfairly taken from them! Marine animals like whales will blossom as, without the threat of humans, will be able to use the ocean to its full capacity and reproduce. It is even predicted that around 300 million years later, there will be a new rational species.

So it looks like earth is very sturdy, and can easily get rid of any trace of us humans, along with the trash we left behind! The video certainly reminds us that it is not earth that needs us, but humans that constantly rely on her! A reminder that we should look after our world. Never underestimate the power of nature!

The Science Behind a Kiss

Why do we kiss? And if you really think about it, where does the act of kissing come from? Today, we as a society have grown to perceive kissing as a passionate and loving act between couples, a sign of respect in more formal situations, even sometimes a tad gross! Either way, not a lot of people would look into this as more of a potentially evolutionary behaviour.

Typically, the average human will spend 20,160 minutes of their lives kissing..wow! Not to mention the world record for the longest kiss stands at 58 hours, 35 minutes and 58 seconds. We could even say that kissing is a type of exercise, burning roughly 2-3 calories per minute. Well that could be one way to avoid the gym! Nevertheless, despite Hollywood films and poetry creating a magical view on kissing, researchers insist this natural behaviour is evolutionary and almost animalistic.

If we look at birds and primates, we can observe the act of ‘kiss-feeding’. This action involves mothers passing pre-chewed food from one adult mouth to the infant’s mouth. A bit weird? Well scientifically, the infant is proven to obtain the nutrients which breast milk is not always able to provide. Not to mention, enabling a much easier way for infants to absorb vitamins like B12.

Evolutionary scientists believe that kissing is potentially a way for us to determine our ideal mate. Emer Maguire from Voices Magazine compares this to a type of job interview, seeking out candidates which best match the description. We do so by ‘taste testing’, as our saliva carries information about ourselves including our level of health, and contains mucus membranes that are permeable to hormones such as testosterone. Does this mean that kissing is actually part of ‘survival of the fittest’, and really, a basic reproductive behaviour?

Interestingly, the actress Alicia Silverstone, famously known for her character ‘Cher’ in the popular 90’s film ‘Clueless’, caused quite a bit of controversy on social media as she posted clips of herself kiss-feeding her own infant. Some of the public may have deemed this as weird-looking, but is this because we only know the evolved version of kissing as opposed to the origin?

So will this newly discovered scientific research change the way we think when we next kiss a partner or loved one? And is there a chance that we as humans will go back to kiss-feeding and deem this as more of a normal maternal act? Either way, kissing is a very natural part of our lives and potentially our survival, so pucker up!
