Some people want to make the wetlands smaller in order to
have more space for farms and buildings. This will lead to less and less space for wildfe. Moreover, fishermen keep fishing there. As a result, the birds do not have enough food to eat. Now the Chinese government has made laws to prevent all these things in Zhalong.
Tip : We use “to”/ “in order to” to express a purpose.
