1 . During a decline in tourism, one national park in Thailand has seen a dramatic rise in “visitors” recently. So many are the hermit crabs （寄居蟹）flooding into the otherwise empty beaches of Koh Lanta that shells （贝壳）for them to live in have become in short supply.
The Thai government moved quickly to ease the housing shortage, launching a public appeal for empty shells that netted over 200 kg. On December 5 these were distributed around the park in a ceremony.
Hermit crabs rely on shells to protect their soft bodies, moving to larger shells as they grow. On Koh Lanta and the surrounding smaller islands, their rapid increase seems to be a natural phenomenon, rather than directly related to the absence of tourists. But the shortage of shells may be man-made：pretty ones have long been gathered to be sold as goods. Crabs had begun to make do with potential death-traps such as plastic caps and bottles.
The shell drive was part of a government initiative to “regain the balance of nature”. “I have instructed all national parks to do whatever it takes,” says Varawut Silpa-archa, the minister for natural resources. His inspiration comes from the pause in tourism brought on by CO VID-19. A ban on international visitors and the closure of national parks have helped nature recover, bringing endangered leatherback turtles back onto Thai beaches. In the coastal provinces of Phang Nga and Phuket, turtles have laid the largest number of eggs for 20 years.
The government has decided to try to copy the short break forced on it by CO VID-19 in future. From now on, all national parks will be required to close for a short period during the off-season and to limit the number of tourists through a reservation system when they are open. Although such restrictions mean reduced earnings from tourism in the short term, in the longer run more parks may help to keep the tourists coming.

2 . The human brain remembers negative experiences more easily than positive ones. Our brains have developed in this way because threats, like dangerous animal, have a more immediate effect on people's survival compared to positive things like food or shelter. As a result, you clearly know what makes you unhappy, but do you know what makes you happy?
Research suggests that our level of happiness is partly shaped by the choices we make. If you've been chasing wealth, fame, power and some material things, you may be looking for happiness in the wrong places. Psychologists suggest that the following habits can make people happier.
People who own close relationships tend to be happier than those who do not. The number of our friends is not important. What matters is the quality of our relationships. Relationships that bring happiness usually consist of the sharing of feelings, acceptance, mutual respect and trust.
People who exercise regularly can improve both their physical and mental well-being. Some research has shown that exercise can be as effective as some medicine in treating depression.
If we are so interested in an activity, we may lose track of time, and we can be in a state of flow. The activity could be playing the piano, surfing the Internet or playing a game. People who experience flow in their work or life tend to be happier.
People are more likely to be happy if they know what their strengths are and can use them regularly. People are especially happy when they can set goals and use their strengths to achieve them.
People, who think positively by being grateful, mindful and optimistic, are more likely to be happy. Being grateful means being thankful. Being mindful means considering, focusing on, and enjoying the experiences of the present moment. Being optimistic means being hopeful about the future.
