Kataria is the founder of the worldwide laughter movement. The celebration of World Laughter Day is a positive activity for world peace and is to build up a global sense of brotherhood and friendship through laughter. The first “World Laughter Day” gathering（集会）took place in Mumbai, India, on 11th January 1998. 12, 000 members from India and international Laughter Clubs attended it. Now there are about 5, 000 Laughter Clubs worldwide on all 5 continents.

    “HAPPY-DEMIC” was the first World Laughter Day gathering outside India. It took place on 9th January 2000 in Copenhagen, Denmark. “World Laughter Day” is now organized on the first Sunday of May every year. Hundreds of people gather worldwide on that day to laugh together.

    Today, the world has never faced so much unrest（动荡）before. People are at war within themselves. Laughter is a universal language, which has the ability to unite humanity without religion（宗教）. Laughter can build a common connection between various religions and create a new world order. So we believe that laughter and only laughter can unite the world, building up a global sense of brotherhood and friendship.

    Studies also say that laughter helps your body do the following: lower blood pressure; reduce stress; work out the heart, especially for those who are unable to perform physical exercise. So in life, when you can laugh, you should laugh loudly and with your entire body—because it's good for you.

    Who wants to eat food that is thrown away as waste? Believe it or not, that's exactly what world leaders did at a lunch held by the United Nations in 2015.

    During the meal, the world leaders enjoyed dishes like salads and burgers made with thrown-away vegetables and fruits. Chef Dan Barber, who helped create the meal, hoped that the experience would make the leaders pay more attention to the issue of food waste.

    It is a huge problem. One out of nine people on Earth does not get enough food. Yet every year over one third of the food produced worldwide goes to waste!

    Why is so much food wasted? Firstly, food is often thrown away before it reaches customers because too much of it is produced, or because it is not kept properly in farms. Secondly, shops and supermarkets usually throw away unsold food. Finally, customers often buy more food than they need, so a lot of uneaten food is wasted.

    How can you waste less food? When eating out, you may ask for less food and take home what is left. Visit fast food restaurant less often, since they usually more wasteful. Encourage your favorite restaurants to give unsold food to food banks.

    You can also waste less food at home. Use smaller rice bowls so that you serve less rice.

    Encourage family members to use unfinished rice to make rice puddings. Tell family members to make a shopping list and buy only what is on the list when shopping for food.

    Food waste is a growing problem and we, either farmers or food sellers or customers, must take this problem more seriously and do what we can to help.
