HEAL THE EARTH

Dear Parents

We all live on planet earth, which is the only planet known to have life……..Mother Earth is the womb of the

sustaining power of humanity. We are nurtured by the healthy condition of Mother Earth. In humans, if the

mother is ailing, the child suffers. In the womb, the child is helpless. But in our case, it is the mother who is

helpless. We, humans are the cause of the ailing planet. We are deteriorating natural resources, diminishing

forests and wetlands, depleting underground water for our own selfish requirements. The consequences are

loss of biodiversity, erosion of soil, rapid extinction of some important animal species, collapse of fisheries,

rising air and water pollution, rise in atmospheric temperature, thinning of ozone layer, regular shortage of

fresh drinking water, vanishing plants etc. The Earth is in trouble because of the way the modern man has

treated Her and for some reason it seems that much of it has to do with human arrogance rather than

ignorance. Even though science and technology have radically altered the terms of adaptations to the nature,

we still need to adapt to the environment and our MOTHER EARTH. We cannot and must not ignore the cries

of our planet to restore a more harmonious relationship with nature, nor must we lose the opportunity to

work harmoniously with each other for common good.

Keeping all these problems and issues in mind, we have taken “HEAL THE EARTH” as the theme for our

Summer Holiday Homework. It will help our children to use their optimum energy, support sustainability,

develop sensitivity, inspire and aware the community towards the need to protect and preserve the natural

assets of our Mother Earth.

On behalf of LAKMS, it is my humble and sincere appeal to all to take positive actions and move from dawn to

dusk towards a greener earth and be green crusaders to spread awareness around us. Let’s all pledge to

protect our planet from ‘Heavy Hands of Humankind’ and implant green thoughts to make our lives a blessing

for the earth.

“Little drops of water Little grains of sand Make the mighty ocean And the beauteous earth” Enjoy the holidays with your kids! God Bless You! With warm regards

Principal Anshu Nakra

“LIVE GREEN, LOVE GREEN, BE GREEN, WE ARE JUST MANKIND…………….. WITHOUT THE EARTH, WE ARE NOTHING.”

1. It’s not just the Taj Mahal—pollution is ruining many other iconic monuments in India:

India’s pollution problem, which came into the limelight after Delhi’s air was declared even filthier than

Beijing’s last year, is even more monumental than we thought.Toxic air spouting out from burning trash and

exhaust pipes has taken its toll on the facades of some of the country’s sacred heritage sites. The impact of air

pollution on the iconic Taj Mahal—whose grand marble edifice is slowly turning brownish-yellow—has been

4

covered by the media for several years now. But over the last few years, many more sites have joined the

queue—their carefully carved and crafted marble pillars of centuries past turning yellow, brown and black.In

Delhi, the white-marbled Lotus Temple, an architectural triumph and pride of the Bahai faith, is wilting under

the onslaught of pollution. The temple was built in 1986 and attracts 400,000 visitors every month. But the

pristine marble has been fading, despite regular maintenance.
