Planting trees, for example, is 3 effective way to improve air quality and support local wildlife in your area. Companies also have a responsibility to reduce 4 impact on the environment by using cleaner energy sources and producing less waste.

The time to act is now — we owe it to 6 children and grandchildren to leave the world in a better state than we found it.
