Examples of sustainable development include crop rotation, sustainable construction practices, solar energy, wind energy and efficient water fixtures. The common element among sustainable development practices is that they don't deplete the resources in use.
Crop rotation, such as alternating wheat with local crops, prevents soil from becoming too saturated with salt or becoming infertile due to a loss of minerals. Another sustainable farming practice is growing crops beside or beneath local crops, such as growing coffee plants in a forest instead of fields solely composed of coffee plants. Comparable sustainable practices in cities include the use of green spaces, which reduce temperatures caused by an overabundance of concrete, glass and metal and which minimize excess water runoff during storms.
Wind and solar energy provide sustainable sources of energy, as they cannot be depleted like fossil coal or gas. While the potential for wind energy is limited by location, modern solar panels make solar energy practical almost anywhere.
Sustainable construction practices include the incorporation of sustainable energy, including solar, wind and geothermal energy, and the significant use of recycled lumber, plastic and metal. Lumber grown with sustainable farming practices also satisfies sustainable construction needs.
Efficient water fixtures reduce water use, which significantly reduces the energy used in heating and transporting water.
