Environmental / natural resources lawyers deal with the government's rules for the use of natural resources, such as air, land, and water. These attorneys also typically have experience working with the government agencies that regulate natural resources, such as the U.S. Environmental Protection Agency or a state Bureau of Land Management. If you are a business owner that may have caused pollution (for example, your underground oil tank leaked), or if you want to use a natural resource for your personal use (for example, water from a river to irrigate your property), an environmental lawyer or a natural resources lawyer can help you understand the complex laws in this area and how to avoid problems.
