A beach is a relaxing place to catch waves, get some sun, and go exploring. Here are tips from experts on how to be a better beachgoer.
Use safer sunscreens
A
1 Many sunscreens say that they are “environmentally friendly”, which has no firm definitions (定义). Only buy mineral-based sunscreens so that they won’t do harm to the sea environment.
Clean up rubbish
F
2 If you forget to bring one, find a used bag at the beach. It may seem a little action, but it will help remove rubbish. By working together, people can really make a big difference.
Buy thoughtful toys for kids
It is fun for your little ones to play with plastic toys in the sand.
D
3 They end up polluting the environment and can be accidentally eaten by animals, causing serious harm. Pack metal or wooden toys instead.
Read the signs
Signs at the beach must be read. They tell you where you can’t go and what you can’t do, so you don’t mess with the local ecosystem.
B
4 They are storm barriers (屏障) and home to many animals.
Destroy what you build
If your children build sand castles or dig tunnels on a beach marked as a sea turtle habitat, knock down the structures. Sea turtles have heavy bodies and they can die if they fall into a hole and get trapped.
E
5 A. The sunlight on the beach is so strong that you need sunscreens.
B. Beachgoers are usually advised to stay off sand hills.
C. Take your rubbish away with you when you leave the beach.
D. However, plastic toys break easily, leaving behind bits and pieces.
E. Sand structures can also prevent them from reaching birthing areas.
F. Bring a reusable bag to clean up while you are walking on the shore.
G. Have your children pick up rubbish with you when walking on the beach.
