Action needed to cure ailing Earth
JOEY LUK PUI-MAN
Will there be a day when there are no birds in the sky and no fish in the sea? And no plants or animals on land? What's happening to our Earth? Global temperatures are going up and we only have ourselves to blame. We consume so much fossil fuel that greenhouse gases accumulate in the Earth's atmosphere.
Worse still, the trees in tropical rainforests that help re duce the greenhouse effect by absorbing carbon-dioxide, are being cut down at an alarming rate.
Most people have ignored government calls to use public transport. There seems to be no significant decline in the number of private cars on the roads. Therefore, the air quality in most cities in the world is un likely to improve in the near future.
But at the moment the priority is to conserve forests - the Earth's lifeblood.
I recommend that more students go on field trips to the countryside which will help them realise the importance of environmental protection.
