  • 2.How Not to Annoy Wild Animals at National Parks National parks are a treasure that offer the chance to view native plants and animals in their natural habitat.However,as the number of visitors and wildlife populations increases,humans and animals too often find themselves in close distance.(1)

       Remember that the animals living in national parks are wild.Wild animals can be unpredictable and in national parks and many state parks,they are not contained.(2)
    Never think that it is safe to approach them.
       (3)
    Stop by the visitor's center and take the time to read about the types of wildlife in the park and what to expect,The park service posts these signs to protect you and the wildlife.So,if you see the warning signs,take care.
       Make sure you give animals space.The general rule is to keep 25 yards away from all wildlife,and minimum of 100 yards away from wolves and bears.(4)
    If you're out hiking and you encounter wildlife,stick your thumb out and hold it out at eye level.If your thumb covers the entire animal,you're a safe distance away from that animal.
       Some wild animals look adorable and maybe you think handing them a snack two won't hurt.(5)
    Feeding wildlife is a bad idea and you risk getting a bite.Plus human food is not healthy for animals and it makes them learn that people aren't the threat.This becomes a vicious cycle(惡性循環(huán))that results in people getting too close and getting hurt.Wildlife have all they need to eat in their environment.

    A.But don't do it.
    B.You can follow the "rule of thumb".
    C.In national parks,there are warning signs everywhere.
    D.At certain times of the year,wildlife can be more lovely.
    E.So it's important to know how to respect wildlife and stay safe.
    F.In another word,they go anywhere within the park as they please.
    G.You should always pack up food after a picnic stop or at the campground.
