The magrove forest is a set of trees that grow in the area around the coastline that is influenced by the tides of sea water and are in places that have accumulated organic materials and pelumpuran. Mangrove forest which is also commonly known as mangrove forest is a unique ecosystem because of the activity of the inundation cycles by the tidal sea water. In this habitat only mangrove trees / mangroves that can survive due to the evolution and adaptation process that has been passed by mangrove plants.

Mangrove forests have a very large function for our environment there are:

1. as a plant that can withstand the flow of sea water eroding coastal land, in other words mangrove plants are able to hold seawater so as not to erode the land in the coastline.

2. As with other plant functions, mangrove also has the function of absorbing carbon dioxide gas (CO2) and oxygen producer (O2).

3. Mangrove forest has a role as a place to live various kinds of marine life such as small fish for shelter and forage. In addition to marine animals, for mangrove forests that ruag fairly large scope often there are types of terrestrial animals in it such as apes and birds.

Of the several functions of mangrove forest described above, surely the most essential thing for our survival is the function of mangrove forests as oxygen producers (O2) and carbon dioxide gas absorber as well as prevention of abrasion. Damage to mangrove forests can result in loss of functions in these. Imagine if the forest is destroyed, there is nothing that can produce oxygen (O2) for us to breathe, not something that can absorb the gas (CO2) which is a poison gas and harmful to the human body, and there is no longer a solid defense that can withstand abrasion rate.

Currently the state of mangrove forests along the coast of Indonesia is so alarming. Most of them are damaged and some of them are discharged due to logging activities and others. This will certainly be bad for our environmental sustainability.

Given the importance of mangrove forests for the sustainability of our environment, there needs to be a solution to overcome the problems that have been happening in mangrove forests. Solutions we can do include:

1. the need for conservation land on mangrove forests in order to maintain and preserve the forest so that mangrove functions can be optimized as possible.

2. reforestation or replanting of damaged mangrove forests. In this case the need for engagement between government and citizens technically in the implementation of reforestation.

3. There is a need for good spatial management of the mangrove forested coastal areas, so that it can be potentially economical in terms of tourism. Provit obtained from this nature tourism can be used for the mangrove conservation needs.

4. the need for counseling in order to understand the importance of the importance of the preservation of mangrove forests for the environment.

5. Strong legal sanctions against anyone who damages the preservation of mangrove forests.

Environmental sustainability is very important to us. Maintaining mangroves is part of the real action of our concern for the sustainability of nature and life. Starting from yourself, let's keep the environment for life and life.
