Opening natural heritage sites to the public would mean people could get to know more about them.
Natural heritage sites are precious and irreplaceable treasures which we should try our best to protect. Only when we have learned them well enough can we protect them in a proper way. Opening these natural heritage sites makes more people understand heritage knowledge and comprehensively improve public awareness of the importance of natural heritage protection. In addition, opening naturalheritsge to the public can raise some money and the money will be in turn used to protect these heritage sites.
As long as proper measures are taken to prevent the destruction
of natural heritage sites, opening them to the public should be encouraged.

Revision
Natural heritage sites should not be open to the public because crowds of visitors can cause damage to them.
First of all, natural resouces will be excessively used to satisfy the visitors' needs, such as fresh water and other raw matrials, which is totally beyond the environment's ability to recover. Another problem that visitors bring to us is pollution, including noise, air emission, solid waste, chemicals and littering. These can onot only disturb the noraml life of wild animals but break the balance of natural environment. Last but not least, some visitors even conduct "uncivilized tourist behavior," including climbing trees, picking flowers and fruits, damaging plants, feeding animals, etc. These bad behaviors sometimes can casue permanent damage to the natural heritage sites.
As far as I'm concerned, in order to conserve them better, natural heritage sites should not be open to the public.
