Environmentalism is the philosophy that the Earth is like a ship far out in the middle of the ocean, and if there's a fire we should make an effort to put it out on the grounds that we have nowhere else to go. Environmentalists are often called Greens. They are fundamentally opposed by the Grays who believe the Earth is like a front yard in the middle of New Hampshire where we can just let the grass grow up to hide/shade the sleeping dogs and leave a bunch of parted out cars laying around leaking oil and transmission fluid, and any effort spent trying to raise the planet's "curb appeal" is socialism and reminds them of when their mothers told them to clean up their rooms. Besides, Jesus is coming any minute now, to clean it all up for us anyway.
 Real environmentalism
Several causes of the environmental movement are genuine:
- Mitigating global warming and reducing greenhouse gas emissions, for example, by promoting mass transit.
- Promoting vegetarian and vegan diets as more environmentally friendly. Meat is 16 times more energy intensive to produce and emits 24 times more greenhouse gases than plants.
- Reducing chemical pollution from manufacturing and agriculture.
- Protection of endangered species.
- Creation of wildlife sanctuaries to prevent local extinction (aka extirpation), and conservation of already existing ones.
- Opposition to the further expansion of the use of fossil fuels.
- Encouraging better industrial and municipal waste management practices.
It is often difficult to accurately assess how we can best protect the environment. To truly understand how sustainable a specific product or process is with regards to environmentalism, life cycle assessments are common.
 Environmental woo
Environmentalism is a necessary response to a negative impact of human activities on nature, but it has occasionally been a realm in which much pseudoscience and woo has flourished unchecked. Science-based environmentalism, based on study of biology and ecology and the formulation of appropriate and effective public policy to curb and mitigate human impacts on same, can be contrasted with such woo as:
- Sunday school environmentalism, in which environmental concepts of limited scope, like recycling, are taken or used in the wrong way due to public misunderstanding.
- Opposition to genetic engineering, particularly of food crops and meat animals, on the grounds of health risks of DNA recombination (the method used to create them) or as-yet-unknown problems.
- Gaian Theory, in which the planet itself is seen as a self-correcting living organism.
- A related notion, popularized in the 1970s by writers like Barry Commoner, is that ecosystems if left alone will seek a natural stasis. While no serious scientist believes this today (ecosystems are always changing and evolving, sometimes catastrophically), the idea persists among some environmentalists.
- Hard green extremists who see humanity or industrial civilization itself as the problem, and want to radically depopulate the planet and go back to an imagined idyllic "state of nature."
- Greenwashing, advertising tactics aimed at convincing consumers that if you buy this magical biodegradable plastic or specially formulated gasoline you are helping to "save the planet"; Clean coal is a prominent example.
- Doomsday scenarios, taking legitimate concern over things like overpopulation and peak oil to an unrealistic extreme, and making prophecies which are either premature or unnecessarily alarmist.
- New Age ideas like earth changes, or that returning to "earth"-based religions like neopaganism is necessary to save the planet.
- Other woo sold to consumers claiming they can conserve energy with it, such as automotive woo making unfounded claims to improve fuel efficiency
- "Earth woo" in general is popular, using symbolism to convey a sense of environmental consciousness. If something has the words "earth," "green," or "planet," or an image of the planet as viewed from space, it is assumed to be environmentally-friendly or part of "green" culture. Uses range from corporate greenwashing to popular books like the Whole Earth Catalog.
Unfortunately, much of the woo has flourished within popular culture even as serious, science-based environmentalism has also flourished. Sorting out the difference can sometimes be a snipe hunt.
 Disputed issues
- Whether or not organic food is beneficial to the environment or just woo is debated. The answer depends on whether one considers reducing the amount of pesticides entering the food chain more important when the trade-off is increasing the amount of land required to grow the same food (up to 40% more), encroaching on open space and wild areas. Another problem with organic farming practices is the dogmatic rejection of genetic engineering.
- The "paper or plastic" question and the "incandescent (including halogen) or fluorescent light" question could likewise be defended either way, depending on which environmental issue has the higher priority (saving trees versus saving the ocean; curbing global warming versus keeping mercury out of the food chain), although with the rising popularity of LEDs further complicates the issue of preferred type of lighting.
- Opposition to nuclear energy is common within the movement, but some environmentalists support it as a measure to fight global warming or as a transition technology towards a society powered entirely by renewable energy.
Denialism is a different sort of environmental woo, pretending environmental issues don't exist in the hope they will go away. It is a double-edged sword; on the one hand, it is an appropriate label for an irrational refusal to confront the reality of environmental problems, but it can also be a club used to unfairly class legitimate dissenters in with the more abhorrent Holocaust deniers.
