Why do Plants and Animals Become Extinct?

When Charles Darwin first introduced his theory of “Survival of the Fittest,” it sparked controversy and criticism. However, over time, it gained broader acceptance as it became evident that certain species were either extinct or on the verge of extinction for reasons explained by Darwin’s theory.

Throughout the evolution of animals and plants, many species have become entirely extinct. Conversely, certain species are currently grappling with the threat of extinction, a concern that has garnered global attention and led to their classification as “endangered species“.

The causes behind the endangerment of species are a complex interplay of natural and human-induced factors. A primary driver of this predicament is the ever-increasing human population. To meet their growing needs, humans encroach on more and more forested areas, reducing available land for wildlife.


Forests and heaths have been cleared to make way for agriculture, extensive deforestation has occurred to meet wood demands, and industries continue to expand, all of which take a toll on wildlife. These human activities, among others, have significant consequences for the natural world.

Hunting and poaching also contribute to the extinction of species. Man has hunted various species to extinction, as seen in examples like the auk and dodo. Pollution is another significant factor leading to this unfortunate phenomenon. Each year, millions of birds suffer painful deaths due to oil spills that coat their feathers, making them unable to fly.

Natural factors, such as adverse weather conditions, food shortages, and natural disasters, also play a role in the extinction of plants and animals.

Endangered Plants and Species

Endangered plant species include helleborine, cheddar pink, monkey orchid, tufted saxifrage, alpine catchfly, and alpine gentian. Endangered animals include elephants, tigers, lions, ocelots, humpback whales, pandas, leopards, rhinoceroses, pumas, polar bears, the giant sable antelope, and more.

Efforts to preserve these endangered species have gained attention at both national and international levels. Measures like creating sanctuaries and implementing stringent anti-poaching laws are being taken to protect wildlife.

Quick Facts

  • Plants can become endangered in ways similar to animals. The loss of natural habitat is the primary cause of plant endangerment, often due to human expansion.
  • Wildfires intensified by factors like global warming pose a threat to plant species.
  • Severe droughts can lead to the death and potential extinction of numerous plant species.
  • Agricultural activities, including land clearance for pastures and crops, contribute to the loss of plant habitats.
  • Some rare and beautiful plants are intentionally collected by humans for various purposes.
  • Extinction is declared when no living individuals of a species remain.

In conclusion, the issue of species extinction is a complex and urgent concern that affects both plants and animals. While natural factors can play a role in the decline of certain species, human activities have emerged as a primary driver of endangerment. The ever-increasing human population, deforestation, pollution, hunting, and poaching are among the key factors contributing to the precarious status of various species.

Efforts to combat this alarming trend are underway at the national and international levels. Conservation measures, such as the creation of sanctuaries and the implementation of strict anti-poaching laws, seek to protect and preserve endangered species. As we navigate the challenges of the modern world, these endeavors are essential to ensure the survival of our planet’s rich biodiversity.

It is our responsibility to address these issues and work collectively to protect the diverse and delicate web of life on Earth. Only through awareness, dedication, and concerted efforts can we hope to mitigate the threats to our planet’s flora and fauna, and strive for a more sustainable coexistence with all species.
