I consider myself to be a liberal, a conservative, and an environmentalist as those designations once meant from the base meaning of the words themselves. Today those terms have been co-opted and have interpretations and connotations that that are at variance with their use as descriptive terms.
Liberals used to be for individual liberty, limitation and control of government and private power, and tolerance of different views and standards of behavior. Now "Liberal" stands for government control of every aspect of life, and tolerance only for a "correct" set of views and behaviors.
Conservatives are against abrupt change, and give the benefit of the doubt to traditional values and customs. In America, the old meaning of liberal is the traditional value and custom! So in America, real liberalism is conservative and resists the return to central, authoritarian power and "politically correct" ideas. Conservatives do not want to go back to the conditions of the past, but they do want to re-establish our founding liberal values. Those who advocate change have the burden of proof.
Environmentalists work to protect and restore the environment, and solve problems generally caused by human industrialization and over population. "Environmentalists" now block reasonable progress and dialog by insisting on draconian solutions that ignore the larger realities of resources, economics, and human behavior. Their "solutions" always put the burden on others, and "pursuing invariably the same object evince a design" other than the protection of the environment.
