Responsible use of water resources is an important factor to consider when discussing sustainability, especially in places like California, which are often subject to long droughts.

Think about the natural resources you used today. Perhaps you used water to bathe or texted on a cell phone with copper, zinc, and other precious metals inside. Everything we use comes from natural resources. However, many resources are being depleted faster than they can be replaced. Sustainability is the practice of using natural resources responsibly, so they can support both present and future generations.
Forests are one natural resource that sustainability groups are focused on conserving. Forests made up about 30 percent of Earth’s land mass in 2015, but that number is at risk of decreasing. In 2018, studies showed that approximately 18 million acres of trees are cleared each year for lumber or agriculture. Deforestation destroys the habitat of other important organisms, including fruits, animals, and mushrooms that humans use for food or medicine. Deforested land also increases soil erosion, limiting the productivity of tree growth. The goal of sustainable forestry is to preserve forest ecosystems. Sustainable practices include planting new seedlings in deforested areas and reducing the number of trees cut down each year.
Especially as the human population grows, it is critical that we reduce our depletion of forests, precious metals, and other natural resources. The world population is expected to increase from 7.6 to 9.8 billion people by the year 2050. To decrease our dependency on fossil fuels, many scientists are researching renewable energy sources. The United States military is testing a vehicle fuel made from algae rather than petroleum. And concerns over freshwater sustainability have led to the development of rainwater harvesters, desalination machines, and even more incredible inventions. A European company has produced a drinking straw that filters bacteria, so people can safely drink water from contaminated ponds and lakes.

Biodiversity refers to the variety of organisms found in a particular habitat. It is important to maintain biodiversity because we rely on it for ecosystem services, which fall into four main categories: provisioning, regulating, cultural, and supporting. The earth provides these to us for free and they are critical to achieving a planet in balance. Use these resources to explore the diverse species that exist across the globe, and encourage your students to become good stewards of life on earth.
The Earth’s natural resources include air, water, soil, minerals, plants, and animals. Conservation is the practice of caring for these resources so all living things can benefit from them now and in the future.
