Advances in agriculture and transportation food more. Empowerment of women in society (more jobs, more. Malthus population size is limited by available resources. Boserup as population grows, innovations increase. 2 theories of population growth: if population exceeds carrying capacity, a crisis will reduce the population (famine, disease, conflict) education, etc. , new agricultural methods will increase production to meet demands. Environmental impact cannot only depend on population. We would blame people (women) in developing countries for having too many babies: but some people have bigger environmental footprint than others, affluence: consumption per person. Income or gdp per person is a common measurement. Higher consumption more energy, materials, food used. Environmental impact cannot only depend on affluence. Incomes and consumption levels are higher in industrialized countries.
