Skyscrapers, Windshields and iPhones

Sand, however, may not be everywhere for long. Yes, those little grains we give very little thought to are running out. Sand is what we have built our cities out of, created our phones from and is even found in most car windscreens. Sand is the primary component in concrete, melted down the make glass and used to create silicon. Sand is, quite literally, everywhere. Sand comes second only to water when it comes to the most used natural resource in the word, with over 50 billion tonnes of the stuff used every year.

Now, the world has sand, one look at the Sahara or an image of the Kalahari from space and that is easy to see. The issue comes with the fact that not all sand is created equal. Desert sand is generally eroded by wind rather than water and as such, is the wrong shape to bind correctly when used to create substances such as concrete. Sand eroded by water and found in river beds, floodplains and beaches is what is used for construction purposes, the industry that makes up the main bulk of our sand consumption. This is the sand that is running out.

Sand Mining and Urbanisation

A large driver of this is the rate of urbanisation. As more people are moving to more cities, new buildings and roads need to be built and these are all built out of sand. The annual amount of construction sand used each year in India has tripled since 2000 and Dubai has such a demand for particular types of sand used for construction that it buys it in huge quantities from Australia. Sand is also being used to literally create more land. Countries including Nigeria, China, The US, Singapore and The UAE have all dredged ocean sand to create new land. This creates long term and often disastrous effects for the natural eco-system.

Mining sand for construction purposes is equally destructive, the churned up sediment created from river bed dredging can disrupt ecosystems and kill plant and aquatic life. Many experts believe that sand mining is a key contributing factor to the shrinking of the Mekong Delta, an area home to a diverse ecosystem, a main area of food production for Vietnam and home to over 20 million people.
To make a bad situation worse, riverbed dredging can cause increases in riverbank collapses, causing further destruction to croplands, homes and eco-systems, and sand mining had been linked to deadly bridge collapses in Portugal and Taiwan.

The Violent Underbelly of the Sand Trade

The sand trade has gotten so lucrative that criminal groups have started controlling the trade in some areas and creating a virtual slave labour in sand mines. In addition there have murders linked to the sand trade and violence in India, Gambia, Indonesia and Kenya has been reported as result of criminal groups operating in the sand trade.

Urbanisation shows little signs of slowing and construction materials are going to remain a highly sought after commodity. As a result, scientists are trying to come up with alternative materials to make concrete from, exploring options such as shredded plastic and rice husks. Methods to more efficiently recycle concrete and glass and create ways to make these products with less sand are also being explored. For now though, we have built our foundations out of sand, the problem is that only makes the ground we have built them on that much more unstable.

Overpopulation, the Lesson from the Super Villains

Overpopulation, the one crisis that movie super villains seem to fixate on. From Valentine in Kingsmen to Thanos in The Avengers, villains really seem to care about humanity’s swelling numbers and the impact this creates. The question though comes with is it something that we should be taking more notice of?

The human population has been rising steadily since the Black Death ended in the 1300s, the most significant rise in population though has occurred within the last 100 years. Since the 1920s the human population has grown by 5.7 billion people. As of February 2020, there are thought to be close to 7.7 billion people on Earth and that number is only set to rise, reaching 9.8 billion people by 2050.

Population Booms in a World of Limited Resources

Although fertility rates are dropping in many countries, third-world nations are still reporting high fertility rates. The UN has reported that 26 African countries are predicted to double their size by 2050 and every continent except Europe and Antarctica is forecasted to continue experiencing population growth over the next 80 years.

This population boom creates a significant challenge in the management and distribution of resources, disposal of waste and land management. Quite simply put, more people need more resources, more space and create more waste. The world however does not offer unlimited resources and this increased demand creates a system that the world will not be able to continue to sustain. Alongside uncontrolled population growth are projected food and water shortages, possibly leading to increased conflict in many areas, increased pollution and increased damage to the environment, further exacerbating global warming and climate change.

It may sound like these super villains might have been onto something with their concern. However, don’t go searching for the infinity stones yet, there are far less drastic ways to control population growth and limit the effects of an increasing amount of people sharing the planet. The first comes quite simply by using fewer resources. The average middle- class American consumes 250 times more water and 3.3 times more food than is needed to survive, cutting down on our over-usage of resources on a global scale will vastly limit the impacts of a swelling population.

The Power of Education and Family Planning

Another solution comes with education. Research has shown that the more educated a population, particularly the female population, is of a country, the lower the birth rate. A study in Ghana showed that women who had completed high school had a birth rate of two to three children whereas women who had no education had an average of six children. This trend can also be observed on a global scale. In Canada, one of the most educated countries the average birth rate in 2019 was 1.5 births per woman. In 2019, Niger, a country with a lower level of education had an average birth rate of 6.8.

Increasing access to family planning programs and lowering the cost and improving the access to contraceptive treatments is another proven method to reduce population growth. Some groups are also advocating for governments to provide incentives for families to have less children.

Creating lifestyle changes and reducing carbon emissions is another way that the impacts of overpopulation can be managed and reduced. Switching to green energy sources, reducing meat consumption, increasing recycling and promoting more sustainable farming methods can all create a positive impact.

So, is overpopulation something we should be taking notice of? Yes. However, before you dedicate yourself to the life of a super villain, there are ways it can be managed and slowed to ensure a bright future for all of us.
