In A Glimpse out the Window by Ruth DeFries, Gregory P. Asner, and Jonathan Foley, it talked about trends seen today about sustainability. The three trends were Societal , Demographic and Health and Energy Transitions.
The Societal transitions reflected on where people live, where they get their food and resources. It showed how although Industrialized Countries produce the least amount, they have the highest per capita food supply and have the most amount of tractors per 1000 people.
The Demographic Transition is the “process of moving from small slow growing populations with high mortality and high fertility to large slow growing populations with low mortality and low fertility rates".
The last are the Health and Energy Transitions. It was the shift from infectious and deficiency diseases to non-infectious and sufficiency diseases like obesity and coronary diseases. And as the income increases, the more energy people require. Poor households depend on wood, dung and agricultural residue, while the rich prefer more fossil fuels and modern fuels such as electricity and nuclear energy.
The overall trend was how as Income/Wealth increases, People go from Wild-lands, collecting food, high fertility, high mortality infectious diseases, to Intensive agriculture, low fertility low mortality non-communicable diseases and modern fuels .
In Conclusion Land patterns can reflect advantages in certain situations, but the range of environmental consequences from individual land use decisions are hard to predict and aren’t considered. Every time someone plants food, puts a building beam, cuts a tree branch, the environment suffers the consequences and eventually the world.
