DO not forget your other mother on Mother's Day - she also needs your love, respect, care and attention. Mother Earth gives us food, water, air, energy and materials and how do we repay her? By wasting her precious gifts and making a mess of our home. Perhaps it is because we live in a big city like Hong Kong, with all its modern conveniences, that we forget where our sustenance comes from. Food comes from fields and orchards, not only markets and supermarkets; clean water comes from rivers and streams, not just reservoirs and taps; fresh air comes from trees and plants, not air-conditioners; and all our manufactured goods, ultimately, come from nature, not just the factory. All the waste we create with our consumption goes down the drain, into the garbage truck, or directly into the air around us and, ultimately, finds its way back to nature, polluting the sea around us and taking up space in landfills and even in our country parks. Mothers, you can also care for your children on Mother's Day and all other days by not wasting - and teaching them not to waste - all the good things that Mother Earth provides. If there is to be enough food, energy, materials and clean water and air for our children, grandchildren and their children, then we must consume less now. Give ''green'' gifts on Mother's Day - a potted plant rather than cut flowers. Avoid over-packaged so-called luxury gift boxes of cakes, sweets, biscuits and chocolates. Rather than spend the day shopping for things you do not really need, enjoy a day in a country park, taking your own food and drink in re-usable containers and, preferably, travelling on public transport. If you eat in a restaurant on Mother's Day, avoid fast food served on disposable dishes and utensils. If you eat at a buffet or a salad bar, do not create waste food by taking more than you can eat. Let us start this Mother's Day by respecting Mother Earth by treading lightly on the planet. One very precious and unusual gift for Mother's Day is to donate $500 to Hong Kong Friends of the Earth and your mother can become a ''founder owner'' of the tropical island of Danjugan in the Philippines. The Philippine islands are under immense pressure from commercial and industrial development. Hundreds of them have already been cleared of their tropical forest cover and many others are under threat. The Philippine Reef and Rainforest Project aims to protect the islands by purchasing land with cash donations. Donors will receive a personalised certificate as well as news and updates twice a year.
