Good human impacts on the environment include reforestation, using clean energy, and protecting natural preserves and forests to maintain the natural biodiversity. Digital ortho-photos are produced by applying corrections to aerial photos using an elevation model. Greenhouse gases, which are only beneficial at certain conditions and harmful when too high, are rising each year due to human activities alone. Small-scale, Tree planting This helps reduce soil erosion because tree roots stabilise the soil. When the winds sweep the sands and dust storms generate, sunlight is trapped in the atmosphere and the reflection of sunlight by ice is disrupted, resulting in more global warming.
