Humans-Guardians of the Earth!

Humans-Guardians of the Earth! 1


“Humankind has destroyed, exploited, mutilated,…….. nature beyond recovery” has been the important notion for years. But actually, there is a right side. The present generation is more onto protecting the environment rather than destroying it. Here are few examples to prove that the human kind has been helping the environment.

Reduced air pollution

Of course, the primary reason for air pollution is humankind. But, there has been a significant reduction in the toxic pollutants’ concentration in the air in the past few years. This can be owed to the scientific advancements that have helped in reducing the harmful emissions which were very high in their conventional counterparts.

According to the U.S. Environmental Protection Agency, since 1970 to 2008 the following reductions in pollutant emissions were savoured by the citizens of 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

Efforts are being made to identify the not-as-of-yet identified species. Then the biggest challenge is to protect these and the endangered species from extinction. Once a species is classified as endangered, it has better chances of recovering as the conservation measures are improving. Chinese giant pandas, Sharks, Manatees, Polar bears, Indian tigers, etc., are endangered species that are rendered protection by declaring certain 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 the extinction of certain species. Recently, UNESCO has declared the 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 the 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, the scientific research is opening new avenues for better results.

Wildfire suppression

Wildfire is a natural, uncontrolled outbreak of fire often occurring in the vegetated areas. These are most prevalent in the forested areas 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 or plant or fungus species that does not belong in an environment but is introduced either on purpose or by accident. For example, the Zebra Mussels smuggled their way into U.S. in 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. Endeavours are made to remove these invading species carefully and bringing back the native species.



Renewable energies harnessing

Fast depleting fossil fuels are demanding the usage of alternate sources of energy. We, humans have learnt to harvest energy from the renewable sources such as the sun, the wind, water (dams, waterfalls), etc. 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, algae, human waste dumping, etc. This reduces portability & usability of water and may also lead to flooding. Governments of such places have invigorated the efforts to clean up these clogs.



Kind of cool, eh? But, these efforts should be intensified for the quick recovery of nature. After all, it is the duty of the guardian to protect the ward.
