Document Summary
Lecture 14: ecological views of the economy (in the context of human population growth) The environment provides us with goods and services: diminished by: The u. s. economy (costs and benefits: what is the environmental cost to produce 11. 7 trillion dollars of gross national. 140 million metric tons of copper (reusable), lead and other metals. 170 million metric tons of wood products (nonrenewable resource) Consumed 630 million metric tons of food (not all of this food is going to nourishment. The produce in the grocery store is wasted (we cannot consume as quickly as we produce it)) Eroded 20 million metric tons of soil. 214 million metric tons of trash (a lot of this trash is not compostable dumped into a compact pile where nothing can break down) 1. 5 million metric tons of hazardous chemical waste. Pretty destructive, even if we only look at the economy: two views of the us economy.
