Humans-Guardians of the Earth!

Must read


“Humankind has destroyed, exploited, and mutilated nature beyond recovery” this has been an important notion for the last few years. However, we don’t talk about how humans have taken a great step towards protecting animals and the environment they live in. The present generation has taken many measures to save the environment instead of destroying it. Here are a few examples to prove that humankind has been helping the environment.

Reduced air pollution

Of course, the primary reason for air pollution is humankind. However, the last few years have seen a significant decrease in the concentration of toxic pollutants in the air. This was possible only because of the scientific advancements that have helped reduce pollutants’ harmful emissions. 


The U.S. Environmental Protection Agency has reported that from 1970 to 2008, the following reductions in pollutant emissions were savored by the citizens of the U.S.

  • Ozone decreased by 14%
  • Lead decreased by 98%
  • Nitrogen oxide decreased by 30%
  • Carbon monoxide by 55%
  • Sulfur dioxide decreased by 52%
  • Particulate emissions fell by 80%

Preserving Earth’s Biodiversity

Scientists are constantly trying to identify any flora, fauna, and other species that are not yet identified. The biggest challenge is to protect these and the endangered species from extinction. Once a species is classified as endangered, it has better recovery chances as its conservation measures are improved. Chinese giant pandas, Sharks, Manatees, Polar bears, and Indian tigers are endangered species protected by keeping them in areas of their natural habitats as sanctuaries.


Coral reefs that provide scientists with chemicals that help in curing many diseases are also under threat. Rigorous efforts are being made to prevent their extinction. Recently, UNESCO has declared Hawaii’s Papahānaumokuākea Marine National Monument as a World Heritage Site.

Captive Breeding

Critically endangered species are bred in controlled environments and are released into the wild when their numbers are adequate. Large blue butterfly, Red Wolves, Peregrine Falcon, Arabian Oryx, black-footed ferrets, Cheetahs, the Golden-Lion Tamarin, California condors, Mauritius kestrels are successfully captive-bred. Though there are only a few strong examples, scientific research is opening new avenues for better results.

Wildfire suppression

Wildfire is a natural, uncontrolled outbreak of fire that often occurs in vegetative areas. These are most prevalent in the forested regions of the United States, Canada, and Australia. Wildfire fighters diligently help subdue the fire from further incineration and protect the dwellings of native animals.

Selective removal of Invasive Species

An invasive species is an animal, plant, or fungus that does not belong to a particular environment but is introduced either on purpose or by accident. For example, the Zebra Mussels smuggled their way into the U.S. through the ballast water of the boats. These mussels cling to pipes causing blockages; adhere to motors and other mussels, wiping out the indigenous wildlife. They thrive there and replace the native species. Endeavors are made to remove these invading species carefully and bring back the native species.


Renewable energies harnessing

Fast depleting fossil fuels demand the usage of alternative sources of energy. Humans have learned to harvest energy from renewable sources such as the sun, the wind, and water (dams, waterfalls). What is more dulcet is that these sources are eco-friendly.

Cleaning the waters

Waterways in some regions get clogged with the accruement of natural debris like algae, human waste dumping, and more. This reduces the portability and usability of water and may also lead to flooding. Governments of such places have made invigorated efforts to clean up these clogs.


We must intensify these efforts for the quick recovery of nature. After all, the guardian must protect the ward.
