The United Nations set up a holiday. In 1994, the UN started World Day to Combat Desertification and Drought (世界防治荒漠化和干旱日), to let more people know about desertification. It is on June 17 every year.

Desertification happens when healthy land filled with water and nutrients (营养) becomes desert. It is dry and unhealthy. Every year, 20,000 km² to 50,000 km² of Earth's land is lost to desertification. In Africa scientists predict (预测) that about 70% of Africa's healthy land will be lost by 2025.

Desertification sometimes happens because of climate change. Big and fast changes in temperature can kill plants and trees.

However, it also happens because people use land too much, and in bad ways, to grow food on their farms. If we grow too many plants in the same soil (土壤) within too short a time, it will take away the soil's nutrients. That can turn the soil into dry sand, like a desert.

The UN suggests some different actions to stop desertification. One is to teach people better ways of farming, including the use of better fertilizers (肥料). Another is reforestation (重新造林). It means planting more trees. Today China has 61 million hectares (公顷) of new land to plant trees—more than anywhere else in the world.

However, in some countries, tipping is the custom (习俗). That's the way it is in the US. It's said to be good manners to tip those in the service sector (服务行业), including your waiter, taxi driver, hairdresser, doorman and so on. The better the service is, the higher the tip will be. But we usually give a tip between 15% and 20% of the bill. It can really put your math skills to the test!

So why is there a strong custom of tipping? In the US, waiters have a very low income (收入). But they can make more money from tips. As a US writer once wrote about her experience as a waitress, "It was difficult and I lived and died by my tips."

Remember these! They must be helpful to us.
