12 Sustainability in Science
• Food security: The condition whereby all people have socioeconomic and
physical access to enough quantity and nutritious quality food that sustains their
food preferences as well as dietary needs.
12.4.2 Application of Sustainability in Biology
• The major applications of sustainability in Biology are diseases, agriculture,
population dynamics, fisheries, carbon cycle, and forestry.
• Sustainable agriculture and organic farming are some of the major applications of
biology that promote sustainable use of agricultural methods in enhancing food
security (Clark 2007).
Food security and sustainability are compatible aspects. Briefly support this
statement.
• The Green Revolution in the twentieth century was made of enhancements to
crop genetics, herbicides, and biotechnology. All these are biological concepts
that were instrumental in revolutionizing agriculture.
What is the status of the Green Revolution?
• Organic agriculture is inherently biological and is the solution to conventional
agricultural methods.
Explain how organic agriculture (using examples) supports the concept of
sustainability.
• Biological farmers promote sustainability using carbon obtained from green
manure, crop residues as well as livestock manures. Green manure is typically
created by leaving the uprooted or sown parts of the crop to wither on a field
in order for them to act as soil amendment or mulch. Plants used for green
manure are usually cover crops predominantly used for this purpose. On the other
hand, livestock manure is organic matter obtained from animal feces that can be
utilized as organic fertilizer within agriculture. It entails applying herbicides and
pesticides to improve soil life.
