59The Role of Greenhouse Gases
quality is improved, livestock methane emissions should be signicantly
reduced. Nitrous-oxide emissions could be avoided by eliminating the need
for fertilizer. The EPA stresses that nding the right sequestration practices
will help lessen the negative effects of all the greenhouse gases.
Other environmental benets of carbon sequestration include the enhance-
ment of the quality of soil, water, air, and wildlife habitat. For instance, when
trees are planted, they not only sequester carbon, but they also provide wild-
life habitat. When the rain forests are preserved, it keeps both plant and
animal species from becoming endangered and helps control soil erosion.
When forests are maintained it also
