A look At The Biggest Environmental Issues in India

The Intergovernmental Panel on Climate Change (IPCC) in its last declaration on climate change said that the goal of preventing the planet from warming beyond 1.5°C "now or never." Reports from all over the world indicate the profound effect global warming is currently having.

1. Air Pollution: A Major Environmental Threat in India

Air pollution is still the most harmful environmental issue in India. The cities such as Delhi and Kanpur are constantly listed at the top of the > most polluted cities in the world. The year 2023 witnessed several occasions when the AQI in Delhi crossed the 400 mark, that is, beyond the range of hazardous gas exposure.

The World Bank estimates that health care and productivity losses related to air pollution in India amount to almost $95 billion annually. So, not only is air pollution a health concern, according to other sources, but also a serious environmental threat in India.

From bustling megacities to seemingly quieter rural areas, a toxic haze often blankets the landscape, posing severe risks to public health and the environment. India consistently ranks among the nations with the highest levels of air pollution globally, with alarming concentrations of particulate matter (PM2.5 and PM10), nitrogen dioxide, and other harmful pollutants frequently exceeding safe limits. This noxious cocktail originates from a complex interplay of factors, including rapid industrialization, vehicular emissions, the burning of fossil fuels for energy, construction activities, and agricultural practices like stubble burning, particularly in the northern states.

The consequences of this pervasive air pollution are far-reaching and devastating. Respiratory illnesses such as asthma, bronchitis, and lung cancer are rampant, placing a significant burden on the healthcare system and diminishing the quality of life for millions. Children and the elderly are particularly vulnerable, facing increased risks of developmental issues and premature mortality. Beyond human health, air pollution also damages ecosystems, impacting plant growth, reducing agricultural yields, and contributing to acid rain, which harms water bodies and infrastructure. The economic costs, stemming from healthcare expenditures, lost productivity, and environmental degradation, are substantial and continue to rise. Addressing this major environmental threat requires a multi-pronged approach involving stricter emission standards, a transition towards cleaner energy sources, improved public transportation, sustainable agricultural practices, and increased public awareness. The air we breathe is a shared resource, and safeguarding its quality is paramount for a healthy and sustainable future for India.

2. Water Crisis: Drying Rivers and Contaminated Lakes

India is famous for its numerous major rivers in the world, but some of them are being reduced or contaminated. The Yamuna River, for instance, has high levels of toxic foam in Delhi. The source shows that nearly 70% of the surface water is unsafe for drinking.

This situation not only illustrates that it is another environmental issue in India, but also that it is a very serious one. The issue of an inadequate supply of clean water affects more than 160 million people. The planet's changing climate and inadequate waste disposal are the other two factors that exacerbate the problem.

With 40 million people infected with waterborne diseases and 400,000 deaths each year, water pollution in India severely affects human health. Moreover, it has a devastating effect on the crops and freshwater biodiversity.

Irrigation water pollution inhibits growth in the field, and polluted wastewater, for example, caused by pesticides, herbicides, and heavy metals, results in a decrease or complete loss of aquatic life as their habitats change.

3. Deforestation and Biodiversity Loss

India’s forests are vanishing in a very disconcerting manner. Between 2001 and 2023, it was realized that over 18% of tree cover in India had been lost, as reported by Global Forest Watch. This has been a major environmental disaster in places such as the Western Ghats and the Northeast, with their high biodiversity.

One other main problem that comes along with deforestation is a list of very important environmental issues of India, a like soil erosion, climate change, and loss of animal species, and the most significant of these is the Great Indian Bustard and Snow Leopard.

4. Climate Change and Extreme Weather Events

India has been facing the terrible impact of climate change for a long time, but it's becoming more and more severe. During the first nine months of 2024, India experienced almost daily extreme weather, which, more than anything else, shows the truth of the matter.

A spate of natural disasters, therefore, indicates that urgent measures for the mitigation of global warming are essential.

One of the prime reasons for the growing environmental problems in India is the following:

• Melting Himalayan Glaciers: The Himalayan Ok, I just hope you live in a part of the world where you can benefit from the glaciers. Glaciers, which are the major drinking and irrigation water sources, are relatively fast dissolving under the warmth of the earth, thereby, a shorter water supply and a decrease in hydro energy generation are observed.

• Rising Sea Levels: Mumbai and Chennai are coastal cities that are now at risk from rising seas, and this could result in flooding, erosion, and migration of the population from the beaches.

• Frequent Droughts: Maharashtra and Rajasthan, the Indian states, are in a permanent state of drought that is largely due to their dependence on agriculture, which suffers, in turn, from a lack of water, and leads to the lives of millions of farmers being affected in myriad ways.

The upward trend in these occurrences underscores the pressing need to take climate change into consideration so as to prevent the potential suffering of vulnerable communities, the loss of ecosystems, and severe economic damage. Immediate actions that aim at reducing emissions and establishing sustainable practices are key factors that are indispensable for ensuring the development of India’s future.

5. Waste Management: The Urban Nightmare

The fast urban growth process in India caused the solid waste management sector to be the most swiftly gaining in terms of environmental problems. Approximately 62 million tonnes of waste are generated in India annually, with the processing of only 30% of it being part of urbanization.

City dumps like Delhi’s Ghazipur landfill, which are filled with garbage, are considered a threat to the environment in the country of India. Plastic items that clog the drains, pollute rivers, and are accidentally eaten by animals have become the leading cause of the death of the latter in such cases.

Conclusion

The situation of environmental issues in India is getting even more complicated, and all the different types of pollution, deforestation, bad waste treatment, as well as climate change, are all part of a major environmental hazard in India.

What is necessary here is for India to have more regulations concerning pollution in air and water, advancements in clean technology, the public to be more conscious, and international cooperation. And with these actions taken, we can only, and only then, we will be able to secure a future that is cleaner and greener.

On this World Earth Day 2025, as we reflect on "Our Power, Our Planet," we must acknowledge that environmental challenges in India represent not just a national concern, but a global one. How the world's most populous democracy navigates these threats will significantly impact our collective environmental future. So, let's recognize that even the smallest changes in our daily habits with immediate effect can contribute to a larger solution, mitigating these growing concerns and fostering a healthier India and a healthier world for all and future generations to come.
