We've squandered a lot of the resources our planet has to offer so now there's a lot of things we're running out of.
Here are 10 things you'd be surprised to learn we are running low on, globally.
Medical research has come a long way where we are able to treat, and even prevent certain diseases from spreading. Sooner than we think, we could actually end up being sent back to the dark ages of medicine.
Thanks to the rise in antibiotic resistant infections, it's quite possible.
More than 50% of the population receives a prescription for antibiotics every year to treat various sicknesses and diseases.
Prescriptions that have been used for decades are being debunked. For example, there are now only two effective treatments for gonorrhea, which affects 78 million people. If left untreated, it can lead to infertility and an increased risk of HIV.
It's time to stock up on M&M's and Mars bars, because everyone's favorite guilty pleasure could be running out.
Producing chocolate is not financially viable. Each new crop of coco takes five years to grow and has to be harvested manually. It can also only be grown in certain areas around the world, typically developing countries.
Most coco plants are grown in West African countries including Ivory Coast, Ghana, Nigeria and Cameroon, who produce a total of 3 billion kilograms a year. Americans alone consume 1.3 billion a year, so production is not able to keep up with the global demand.
Increase in fair trade laws has also made it difficult for farmers to financially keep up, so who knows how long this industry will last.
While this one may seem hard to believe, because if you go to any beach you will find sand for miles. Deserts are also full of this stuff and they make up 33 percent of the world's landmass. So how can we be running out?
Sand is the most essential item in concrete, and humanity uses a lot of concrete. While the United States uses a lot of concrete, it's nowhere near how much China has been using. Between 2011-2013 China built 32.3 million houses and 4.5 million kilometers of road. By doing this they used more cement than America has used in the entire twentieth century.
Desert sand is eroded by wind, not water, which makes it too fine to be used in construction. This creates a problem where our demand will not be able to keep up with supply.
At this rate, construction workers will need to seek alternative materials in the next 50 years.
With the way we have been treating our marine life, it's estimated that we could run out of seafood by 2048. This is a huge problem because more than a billion people worldwide depend on fish as their primary source of protein. Also, 120 million people rely on fishing as their primary source of income. It would be a huge impact felt around the world, if we ran out of fish.
Gold is one of the most sought after luxuries in the world, and it's also one of the more rarest elements.
Since it's so hard to find, we only have twenty years worth of mineable gold reserves left.
After all the gold has been mined, it's value will skyrocket, causing the rich elite to invest in the commodity as opposed to things like real estate, which will stimulate the economy. This could have a serious impact on some of the biggest world's superpowers.
