the oldest ocean floor is only 180 million years old, because the oldest crust is destroyed at subduction zones.

What are subduction zones?</h3>
According to NOAA, tectonic plates are fragments of the Earth's hard outer layer that steadily travel across the surface of the globe over millions of years (opens in new tab). (This is a fundamental principle of the theory of plate tectonics, which holds that pieces of the Earth's crust slide across the lower mantle and carry continents with them.) According to the U.S. Geological Survey(opens in new tab), the Earth's crust and the top part of the mantle, a thick, heated layer under the crust, make up that outer layer, also known as the lithosphere (USGS). This lithosphere material curls downward into the heated mantle during subduction zones, when two tectonic plates collide and one slides beneath the other.

The most abundant fossil fuel is coal... Coal isn't only our most abundant fossil fuel,it's also the one with perhaps the longest history. The U.S. has more coal reserves than any other country in the world. In fact, one-fourth of the all the known coal in the world is in the U.S.
Answer:
Aquatic animals and organisms thrive in coral reef habitats/ecosystems. The biodiversity of different organisms (like fish) are abundant because of the habitats (like anemone), algae, and phytoplankton that live off the area. The destruction of the coral reef by polution can cause a disturbance in the balance of life. For example, the bacteria and algae (autotrophs) that live off the sides of pieces of coral would die off causing the fish and other things that way them to die off and then the fish that consume those animals would die off.
In shorter terms: the physical damage would throw off the balance of the food web/food chain and would destroy habitats of thousands of organisms causing them to die off.
Hope this helps! :D
I would say that herding and livestock would not be a major economic activity in SE Asia and that logging, farming and manufacturing are important economic activities. For example, farming produces rice and also tea in this part of the world.
Answer:
Population growth (or decline) is influenced by many factors that fall into the broad realms of demographic characteristics, socioeconomic conditions, transportation infrastructure, natural amenities, and land use and development across space and time.
