E. Why is the use of pesticides harmful to both people and the environment? What could be a good alternative to pesticides?

Pesticides have become deeply embedded within our agricultural system, playing a crucial role. Despite their intended purpose of eradicating specific pests, a significant portion of these chemicals inevitably veers off course, affecting unintended targets. Excessive pesticide usage poses a threat to non-target species as well. Through runoff and pesticide drift, these substances find their way into far-flung aquatic habitats, grazing lands, human settlements, and untouched regions, resulting in adverse consequences for both people and the environment. Embracing integrated pest management and sustainable agricultural practices like polyculture offer more viable alternatives to the excessive reliance on pesticides.

The Editor

The Rising Nepal

Kathmandu, Nepal

Dear Editor,

I am writing to highlight the utmost importance of Nepal’s natural resources and to advocate for their preservation for the betterment of our society and the environment. Nepal is blessed with abundant natural resources, ranging from pristine forests and diverse wildlife to majestic mountains and powerful rivers. These resources not only contribute to our economic growth but also play a crucial role in maintaining ecological balance and ensuring the well-being of present and future generations.

First and foremost, Nepal’s rich forests are vital for our survival. They provide us with clean air, help mitigate climate change by absorbing carbon dioxide, and serve as habitats for countless species of plants and animals. Forests also play a significant role in soil conservation, preventing erosion, and maintaining water quality. It is imperative that we prioritize sustainable forestry practices, such as afforestation and reforestation initiatives, to counter deforestation and ensure the long-term health of our forests.

Furthermore, Nepal’s towering mountains, including the iconic Himalayas, are not only a source of immense natural beauty but also attract millions of tourists from around the world. These mountains support diverse ecosystems, harbor rare and endangered species, and provide critical freshwater resources through their glaciers and rivers. Preserving these delicate ecosystems and adopting responsible tourism practices are essential for the conservation of our mountains and the communities that depend on them.

Additionally, Nepal’s rivers are the lifeblood of our nation, providing water for agriculture, hydropower generation, and sustaining aquatic life. It is crucial that we prioritize the responsible management of our water resources, ensuring equitable access and promoting efficient and sustainable use. Implementing comprehensive water resource management plans, emphasizing conservation measures, and adopting modern irrigation techniques will help us safeguard this invaluable resource.

To effectively preserve our natural resources, we must also address the issue of pollution. Air and water pollution pose significant threats to our ecosystems, public health, and the overall well-being of our citizens. Implementing and enforcing strict environmental regulations, promoting clean energy alternatives, and raising public awareness about the importance of responsible waste management are vital steps towards combating pollution and protecting our natural resources.

Education and awareness play a pivotal role in fostering a culture of environmental stewardship. We must prioritize environmental education in our schools and communities to instil a sense of responsibility and respect for nature among our citizens. By promoting sustainable practices and engaging in eco-friendly initiatives, we can collectively contribute to the preservation of our natural resources.

In conclusion, Nepal’s natural resources are invaluable assets that need to be protected and managed sustainably. By preserving our forests, mountains, and rivers, and addressing pollution, we can ensure a sustainable future for generations to come. Let us join hands and work towards the conservation and responsible use of our natural resources, embracing our role as custodians of this beautiful land we call home.

Yours faithfully,

Sanju Nepal
