Life as the World Evolves

According to the United Nations (UN), the world’s population is more than three times (3x) larger than it was in the mid-twentieth century. The global human population reached 8.0 billion in mid-November 2022 from an estimated 2.5 billion people in 1950, adding 1 billion people since 2010 and 2 billion since 1998. The world’s population is expected to increase by nearly 2 billion persons in the next 30 years, from the current 8 billion to 9.7 billion in 2050, and could attain nearly 10.4 billion in the mid-2080s.

As humans, our life expectancy has seen a notable increase although, we face a high rate of mortality. This high rate of mortality can be termed as “contradictory” because our health system, the standard of living, and overall improvement in terms of our basic amenities have been boosted by scientific and technological advancement. Regardless of these advancements, the mortality rate plunged to 60.12 million people in 2021 around the world. This implies 164,711 each day, 6863 each hour, 114.38 each minute, and 1.91 each second. The lowest number of total deaths per year was 46 million in 1977, and the highest total death is projected to be 121.7 million will be in 2099 (Source: UN (World Population Prospects 2019).

In view of these statistics, one must wonder why our mortality rate increases despite the improvement in life. But this discovery is not far-fetched, as our lifestyles are the leading cause of this alarming figure. We tend to adopt poor lifestyles, eat in an unhealthy manner, partake in risky activities and perform dangerous transformations that disrupt our regular biology as humans and lots more. Some leading causes of death in today’s world are:

  1. Ischaemic heart disease
  2. Stroke
  3. Chronic obstructive pulmonary disease
  4. Lower respiratory infections
  5. Neonatal conditions
  6. Trachea, bronchus, lung cancers
  7. Alzheimer disease and other dementias
  8. Diarrhoeal diseases
  9. Diabetes mellitus
  10. Kidney diseases

 

The counterbalance to this demise is that around 140 million babies are born every year in the world. That’s more than four births every second of every day. More than half of all births take place in Asia with 25 million births in India and 16 million births in China alone every year. According to the World Health Organization (WHO), the global life expectancy at birth in 2019 is 73.4 years and the highest cause of mortality is attributed to ischaemic heart disease (IHD) which amounts to 8.9 million in 2019. We need to become more health conscious and avoid lifestyles that have an adverse effect on our health deterioration. Stay informed, drink lots of water, and be guided!!!
