According to Reuters, resource scarcity refers not only to materials that we need in order to build EVs and other goods, but also to water and food.

Also, UN experts believe that this will be even more of an issue as the Earth might be supporting an additional 2.4 billion people by 2080.

Stephanie Feldstein, population and sustainability director with the Center for Biological Diversity, said that "every single person needs fuel, wood, water, and a place to call home."

Countries in Africa are likely to be most affected by climate change and supply issues, as the population in these regions is expected to grow significantly and they already struggle with issues generated by climate change.

South of Sahara, for example, there are already around 738 million people that lack proper food supplies and the population in the respective countries could grow by 95% be 2050 if experts' estimates are correct.

John Wilmoth, director of the U.N.'s population division, said that the 8 billion mark represents "a sign of human success, but it's also a great risk for our future."

The one billion population growth that happened in the last 11 years can be attributed mostly to countries in the middle of Asia, as they account for about 700 million births since 2011.

While countries like India are set to become the first in terms of population and overall birth rate, the US, Europe and Japan are among those that see a declining number in newborns.

China also dramatically reduced its population growth rate after the implementation of the One Child Policy.

"A big part of this story is that this era of rapid population growth that the world has known for centuries is coming to an end", Wilmoth added.

Some experts warn that coastal regions, which are mostly composed of fairly large urban settlements, will be affected in the future by the rising sea levels.

"The coastal zone is disproportionately urban," says Deborah Balk, a demographic researcher at the City University of New York. "About one in 10 people live in the low-lying coastal zone."

At the same time, there are researchers who believe that Lagos in Nigeria will be the largest city by 2100.

Also, the increase of human population on Earth coupled with climate change is likely to cause more conflicts in the future.

It's not only about us, as nature could be severely affected if we're not careful, since just as human settlements are expected to grow, our consumption of natural resources and competition with wildlife is also likely to increase.

John Wilmoth states that the way we affect nature "has more to do with how we behave than how many we are."

This means that policy makers must find ways to balance how much we consume to prevent the destabilization of ecosystems.
