The factor that CITES fail to consider when determining which species to cover is the Ecosystem sustainability.
A sustainable ecosystem is a biological environment with a series of habitats that is able to thrive and also support itself without outside influence. it is the capacity of the biosphere to meet the needs of the present generation, without hindering future generations from being able to meet their needs.
Answer:
Both physical and chemical weathering, along with erosion, can change Earth's surface as physical weathering allows breakdown of rock into smaller pieces, these pieces can be move from one place to another through water, wind or ice (erosion), and when the smaller pieces will settle down at a place, rain water can react with the soil or smaller rock pieces to form rock minerals.
For example: Running water, wind, and rapid heating/cooling allows the rocks to break down into smaller pieces or grains (physical weathering), then the small grains are transported and settled away from the source area through wind or river (erosion), and at the end the surface area exposed to air for chemical weathering.
