Document Summary
Tells you the rate a population is increasing based on birth and death rates. Rni: birth rate (natality) - death rate (mortality) In 2014, this number was 54% and growing. Gives us a rough estimate of the number of potential providers of support per potential elderly dependent. Subtracted from age of working people (15-64) divided by elderly persons (65+) Biodiversity is the variety of life in the world or particular habitat or ecosystem. Means healthier farms and surrounding lands that have the ability to adapt to change. Means more options for actual crops and resiliency in case of weather conditions, pests, etc. Greater species diversity ensures natural sustainability for all life forms. Organic outperforms conventional in years of drought. Organic farming systems build rather than deplete soil organic matter, making it a more sustainable system. Organic farming uses 45% less energy and is more efficient. Conventional systems produce 40% more greenhouse gases. Organic farming systems are more profitable than conventional.
