Attach Importance to Nature

The natural world encompasses a remarkable diversity of ecosystems, with each inextricably linked to the other. Francis Bacon, an English philosopher, once said: “Only by obeying nature can we control nature.” As humans, no one can ignore the fact that we often overlook the interdependence with nature, and therefore fail to wholly understand the impact of nature on human life. This essay aims to indicate the connection between life of underwater and land and human existence.


This gives an example of the typical food chain in a marine habitat, demonstrating the interactions between various species. For instance, zooplankton feeds on phytoplankton, which in turn provides food for beneficial animals and mammals, and phytoplankton uses photosynthesis to make organic matter. Due to their mutual dependence, these organisms work together to preserve ecological balance. Also, the water region serves as a fishing ground for fisherman, who use their catch to supply humanity with an abundance of seafood, particularly for people living near the coast. Fishing and aquaculture are two sectors where selling seafood generates revenue.


The Global Coral Reef Monitoring Network (GCRMN) report states that since the 1980s, there have been at least four significant global coral bleaching events. From 2009 to 2018, there were approximately 14% of corals that were severely damaged, meaning that 14% of corals had vanished from the reefs. Coral bleaching upsets the equilibrium of the ecosystem and serves as a home for a variety of marine animals, such as fish, invertebrates, and algae. The primary reasons of coral bleaching, according to scientists, are rising ocean temperatures and global warming. The increase in human demand for necessities like food, clothes, shelter, and transportation is the root cause of global warming.


As mentioned in the South China Sea Institute of Oceanography (CAS) of the Chinese Academy of Sciences that “marine pollution is a major” culprit “for the imbalance of marine ecosystem. When marine pollution occurs, the first thing to be harmed is marine flora and fauna, and the ultimate damage is to human interests.” 


Consequently humans need to protect the water environment, reduce overfishing and pollution, to ensure the diversity of fish numbers and species, and maintain ecological balance.


Moreover, the interaction between underwater and terrestrial organisms also plays a crucial role in climate change. According to a research conducted by the Intergovernmental Panel on Climate Change (IPCC), it’s estimated that since 1970s, the ocean has absorbed around 90 percent of the excess heat generated by human activities. And the ocean and vegetation take in half of the carbon dioxide we produce, trees absorb carbon dioxide, reduce its concentration, and undergo photosynthesis to convert carbon dioxide into oxygen and organic matter, and release oxygen, which can ease the impact of global warming on humans.


In a word, human life is closely related to nature, they are like a loop. As those of us who use natural resources, we have a responsibility to protect the harmony between humans and ecosystems.
