Developing and flourishing, you glimpse down revealing a flexible long and green structure you are attached to alongside multiple strands branching out ending with a 2d oval like structure. 

If you are reading this as a human then yes, well done you’ve figured it out. You are indeed a species of plant. But this is just a group composed of many many many many many and many varieties of individual species alongside other groups of living organisms. Living organisms are present all across our planet from countless habitats from rainforests to grasslands and their survival is heavily dependent on the conditions of their ecosystem. 

Air pollution strives as the main impact of ecosystems with sulphur and nitrogen emissions affects the ability for producers (first level of the food chain/web) to grow. The increased acidification caused by this ultimately affects the ability of an ecosystem to provide natural nutrients for living organisms in the area. Increased ground-level ozone also causes damage to cell membranes on plants initiating key processes required for growth and development further reducing the stunting the flow of an ecosystem. This loss of biodiversity in plants affects not only the organisms which require its resources but us, as humans, where at every second our body replenishes the gases in our body in order to survive. The loss of biodiversity inevitably results in lower plant growth which equally results in lower photosynthesis meaning less filtering capacity to clean our air. 

As a captivated biology student myself, I find that much of this information is taught in class and well covered in the IGCSE syllabus which I am heavily satisfied with. Examples such as the functions of the carbon cycle or the consequences of deforestation in topics/units allow me to further understand the current dire situation of the ecosystems on our planet. After extensive research, I have actually discovered that there have been multitudes of recorded conducted research mostly based on monitoring and assessing the air pollutants and its effects than actually taking action and trying to reduce the causes, unfortunately.
