1.0 INTRODUCTION Australia has a total of 11,000km of mangrove-lined coastline, making up 18% of Australia's coastline, but only 1% of Australia's total forest cover . Mangroves play an important role in the oxygen we breathe today, they are also home to at least 70 different species of crustaceans and around 75 different species of fish and over 100 different species of molluscs, and even polychaete worms and 230 species of birds. Some species live in mangroves only during high tide, such as sea snakes, turtles and even crocodiles. All of these organisms are affected by human impacts, such as sedimentation caused by construction and excavation, water and air pollution caused by large factories releasing chemical waste into the water and air, and deforestation, a way to make money and clear land to build things like factories or mines. These are just three of the serious problems that put organisms and even people at risk, all caused by humans. All organisms are interconnected in their world – no matter how small or large – there must be a balance with their environment to survive. Even the smallest disruption in the food chain, such as the elimination of one species, could result in the elimination of hundreds of species. Rapid environmental changes within an area, biome, or planet can affect biodiversity and cause mass extinction. This is the enormous role that humans play in the biodiversity of this planet.2.0 THE ENVIRONMENTAL IMPACT2.1Mangroves live in the intertidal zone, an area that is above water during low tide and underwater during high tide. Mangroves provide great value to the environment such as shoreline protection, growth of threatened and endangered species. Mangroves protect coastlines from damage such as erosion, cause... half of paper... data has improved, so maintaining current efforts is the only thing that needs to be done.5.4 KEY PERFORMANCE INDICATORS6.0 CONCLUSIONIn conclusion, all organisms are important to the environment they live in, no matter how large or small, there must be a balance to survive. Even the smallest mistake can have serious repercussions on the environment around it. Mangroves play an important role in the air we breathe and most people don't know it, even if they don't know it, creating awareness about mangrove deforestation can bring great benefits to the entire world. Using scientific equipment to collect and store data on mangroves gives ecologists a better understanding of where mangroves live, this makes it easier for ecologists and also locals surrounding mangroves to take action to maintain and/or restore the environment around them..
