Effects of global warming, human activities on wetlands and the need to take action |

Although wetlands provide various socio-economic benefits to our society, more often than not, socio-economy development is pursued at the expense of the environment. However, this has been proven to be unsustainable and inefficient in the long term. Wetlands are filled in, dredged, ditched, dammed, polluted, created, destroyed, farmed, diverted, etc. We mitigate for wetland loss by digging ponds which by definition are not wetlands. We use them to treat waste water and damage them for production, recreational and plant production purposes. Since wetlands are frequently found at the interface between terrestrial and aquatic ecosystems and are strongly dependent on the water cycle, they are extremely vulnerable to the effects of climate change, not to mention the effects of the deviation of wetlands are extremely harmful and detrimental, including shoreland retreat, salt intrusion or even increasing floodings. These shifts have been the conduit to many of the adverse impacts. Expansive sea level rise not only increases floodings but also means more melting ice glaciers. Without ice to block sunlight, photosynthesis rate increases, leading to longer growing season and longer plankton growth, a necessary substance to the. Stronger winds piled plankton at Antarctica, while it remains scarce at other places. What is more, due to altered wind patterns, nutrients are transferred from the upper ocean to the deep sea, thus making marine species to the north starve for nutrients. Secondly, the changes of wetlands subjects marine species to extinction, which poses a major threat for fishing production and productivity. As a result of global warming, seawater is replenished with carbon dioxide, which intensifies acidification within. Thus, the lives of many marine species, such as coral reefs, are threatened by this booming phenomenon of such harmful substance. At many areas, increasing Northen Hemisphere sea rise is predicted to cause East Asian moonsoon summerand desertification in Eurasia, which subsequently has a negative impact on local food production ?Although preventing a global warming phenomenon would require a global consensus, responding to its consequences is our own individual awareness.? Despite exasperating conditions wetlands are encountering, with steps and the right mindsets, the accumulation of negative effects can be enormously subsidized, which not only saves the wetland environment, but also the planet Earth we are residing in. |

Hello Bao!
The lost of precious wetlands and accelerating global warming speed is truly a big threat to every living thing on Earth. These no only effects the marine system but also leads to interference in every single lives. So what can we do to mitigate these disaster from happening?
Let's think about this in every aspects including politics, engineering and etc.
Nice report!!
