Being an eco-friendly tourist

Millions of homes and businesses around the world will turn off their lights to mark Earth Hour on March 27.

But why limit your concern for nature to that one hour, every year? We tell you how to play earth warrior to perfection, whenever you set out on holiday, without having to permanently hang up your boots.

We wouldn't ask you to stop flying considering its convenience factor, but do fly smart. Day flights tend
to be less polluting. Since take-offs and landings lead to the maximum carbon emissions, book a direct flight to your destination.

Carbon offsetting is a way of making up for the pollution your flight caused. You can do this by planting
a tree or a similar green act. Websites like www.climatecare.org and www.co2balance.com can also be pretty useful.

While travelling, avoid renting a car or taxi. Taking local transport will also have you mingle with locals and can be quite an experience. If possible, walk or ride a bicycle and enjoy the landscape.

Backpack or camp in the open or opt for a home stay, which is a fantastic way to experience local culture. Or book yourself into a green hotel.

While picking up souvenirs, don't take back anything from natural areas. Avoid picking up shells from the beach, things made from animal products or endangered plants and animals.

Volunteer while you travel. Teach English to the local kids, clean up the place, whatever works for you.

Be sensitive to the locals, culture and customs. Take personal responsibility for your actions and do not make unreasonable demands (don't demand a pizza while travelling to India's interiors).

As they say, take only photographs and leave only footprints. Not the carbon ones, though.
