Some plants use a lot of water, and some are very drought-tolerant. Drought-tolerant grasses are good for water conservation because they require less water to grow and stay green. How much less water do they need? Which types of grass are drought-tolerant? You can buy different types or brands of grass seed at your nursery that claim to be drought-tolerant. Grow them in a container and then starve for water after they are established. Which brands die out first? You can conduct a similar experiment using sod, or lawns that are already established with different species of grass. Just make sure to get permission from the owner first! Then you can mark off your study area with stakes and starve the area for water. Which types of lawns are the most drought-tolerant? What about other landscape plants? Are native plants more drought-tolerant than exotic plants? You can actually calculate the amount of water that each type of plant needs, then compare the water needs of different plants. How much water can drought-tolerant plants save annually? Can you extrapolate this to estimate the amount of water that can be saved by an entire community? A city or regional park? Can you propose some good plants for landscapers to use that will save water? (National Arbor Day Foundation, 2006; NPS, 2006)

Have you ever visited a new city and marveled at how nice looking it was? Perhaps the streets were wide, the public places were well organized, and the parks and gardens were green and had lots of attractive plants. Well, what you experienced was a well-balanced and designed landscape plan put together by a landscape architect. Landscape architects design everything that is outside of buildings. Their goal is to make a design that is functional, but one that is well balanced with nature and in… Read more

Soil and water are two of Earth's most important natural resources. Earth would not be able to sustain life without nutritive soil to grow food and clean water to drink. Soil and water conservationists foster the science and art of natural resource conservation. The scientists work to discover, develop, implement, and constantly improve ways to use land that sustains its productive capacity, and enhances the environment at the same time. Soil and water conservationists are involved in improving… Read more

Have you ever noticed that for people with asthma it can sometimes be especially hard to breathe in the middle of a busy city? One reason for this is the exhaust from vehicles. Cars, buses, and motorcycles add pollution to our air, which affects our health. But can pollution impact more than our health? Cutting down trees, or deforestation, can contribute to erosion, which carries off valuable topsoil. But can erosion alter more than the condition of the soil? How does an oil spill harm fish… Read more
