Forests play a critical role in mitigating climate change because they act as a carbon sink-soaking up carbon dioxide that would otherwise be free in the atmosphere and contribute to ongoing changes in climate patterns.
Remember the 4 R's- Refuse, Reduce, Reuse, and Recycle. Communing with nature is more resource-friendly than going to the movies or restaurant or mall. You can also save water outside the house with a sleeping lawn or by xeriscaping.
