2. Reflect on long-term changes.
(iii) A carbon footprint is the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by the actions of the humans. The average carbon footprint for a person in the United States is 16 tons, one of the highest rates in the world. Globally, the average carbon footprint is closer to 4 tons. For example, the carbon footprint of a bottle of water includes the CO2 or CO2 equivalent emitted during the manufacture of the bottle itself plus the amount emitted during the transportation of the bottle to the consumer. Decreasing the carbon footprints is referred to as carbon offsetting. It can be achieved either by decreasing the amount of energy required for production or by decreasing the dependence on carbon emitting fuels.
(iv) Population explosion is the rapid and large increase in the number of a particular species. The growth in population of humans has led to the socio-economic and ecological problems like poverty. This is due to increased illiteracy and low awareness. First, rapid population growth is likely to reduce per capita income growth and well-being, which tends to increase poverty. Second, in densely populated poor nations with pressure on land, rapid population growth increases landlessness and hence the incidence of poverty. Thus both the terms population explosion and poverty are inter related.
