Temperate deciduous forests face many issues that are depleting its resources. Some of these environmental threats include deforestation and logging, acid rain, and human invasion to industrialize these areas. Since so many factories and industries are located so close to these forests, they pollute the atmosphere and cause harmful effects on the ecosystem. Because of this, many locations of temperate deciduous forests are in natural preserves or national parks in order to protect the species and beauty of the woodland. One example is Olympic National Park in Washington. Olympic National Park maintains the natural elements of the ecosystem while protecting the wildlife inside of it. It is very important that we prevent deforestation and reduce air pollution in order to save the temperate deciduous forests that are beginning to dwindle in numbers.
