Marine ecosystem, climate change a deadly combination 

Oceans cover almost 70 percent of earth's surface; thus, they have significant importance to global environment. Besides it is also responsible for the majority of heat transport and rainfall. Additionally, it harbors diverse ecosystem, complicated food waves and food chains. The bad news is they are the ultimate site for deposition of non-degradable wastes and chemicals. The river current transports them sooner or later. Also, the impact of climate change and global warming is easily visible across our oceans and coastal areas. 

There are three major threats to marine ecosystem- due to global warming, due to the dumping of trash and due to change in microclimate. Global warming can wipe away entire species and has been doing such as it favors invasive species. The increase in water temperature to even a slightest may severely affect the internal body physiology and metabolism of marine animals. Our plastics and other non-degradable waste have reached everywhere- from the ice desert of Antarctica to beautiful coastal line of Maldives. They are pushing these species away. Sometimes wipe away the entire ecosystem. Important issue of marine ecosystem is microclimate, if the dedicate balance is disturbed earth has witnessed loss of species as a whole. 

In marine ecosystems, rising atmospheric CO2 and climate change are associated with concurrent shifts in temperature, circulation, stratification, nutrient input, oxygen content, and ocean acidification, with potentially wide-ranging biological effects. Population-level shifts are occurring because of physiological intolerance to new environments, altered dispersal patterns, and changes in species interactions. Together with local climate-driven invasion and extinction, these processes result in altered community structure and diversity, including possible emergence of novel ecosystems. Impacts are particularly striking for the poles and the tropics, because of the sensitivity of polar ecosystems to sea-ice retreat and poleward species migrations as well as the sensitivity of coral-algal symbiosis to minor increases in temperature.

    Hello Sachin

    Thank you for the detailed explanation about the impact of climate change in marine environment. From your report, I can see that the earth is balanced in extremely precise way that even little unbalance can cause huge impacts. Therefore, human society should focus on sustainable development, which does not break the balance of the nature.

    Thank you for the great report.

    Hey Sachin!
    It's Lisa your mentor:)

    Nice to see you back here!
    And I can see that you have done some research to write your report. Nice job dear!

    As you have well put, climate issue does affect marine life negatively as well as it does for other parts of the environment. Rise in the level of CO2 in the sea is a serious threat to many living things in the marine ecosystem. The confusion it causes breaks the food chain as well!

    I really agree with you that the earth is losing its balance, symbiosis as well. We should do something so that the earth can get its balance back so that it will be able to solve minor problems on its own, like the way it did before!

    Thanks for your contribution in Tunza community and keep up the good work:)
