Every high school graduate should understand topics in global climate patterns, terrestrial biomes, coping with the environment and heat, evolutionary ecology, life history, behavioral ecology, population distributions, growth, dynamics, and regulation, symbiotic relationships, communities, biogeography, diversity, productivity, food webs, nutrient cycling, and conservation biology. I believe that all these topics should be covered to some extent in high school because it opens up a new perspective to have a broader understanding of everything in ecology. In high school we covered all these topics briefly except for population dynamics, diversity, productivity, conservation biology, and biogeography.
I think it would be beneficial to go into these topics more especially since a major driving force for ecological relationships and balance within ecosystems is how populations function, and can be affected by certain factors. Especially because humans are a major cause of population fluctuations and extinction. This is why i also think conservation biology should be a focus because with thousands of species becoming extinct each day and year, we have to work hard to stabilize and increase populations of endangered species, and prevent further species from going extinct.
