This world has been defined by humans to be for humans.
Placing humans at the center of the world is called anthropocentrism.
This anthropocentric view of the world has resulted in environmental destruction. Mountains, rivers, savannahs and entire rainforests, are nothing more than material possessions, objects to satisfy humans.
This view also allows humans to regard animals as "natural resources", as objects for their use.

Environmentalists are no different than other humans. Almost all the environmentalists we have met consume meat, eggs, dairy products, leather, coffee, tea, cocoa etc. Most of them drive a car too. All are environmentally destructive industries.
There is no other way to explain environmentalists that consume animal products, which are the number one cause of ecological damages, other than selfishness, hypocrisy and anthropocentrism.

Rainforests for example are a primary concern of anthropocentric environmentalists for many reasons, which reveal their human-centered bias. They complain that species of plants and animals are becoming extinct as the forests are destroyed. And why is that important? Because humans might lose potentially beneficial medicinal plants, and because the loss of animal species reduces the world’s gene pool and robs humans of rich, varied biological resources. They cry for saving the rainforests, because "their planet" depends on it.

Environmentalists protect the environment for themselves. They want to keep watching endangered species for their interests, not for the sake of reducing these animals’ suffering. An animal from an endangered species suffering is not more significant than the suffering of any other animal. Environmentalists do not see individuals, only ecosystems. And they don’t see suffering only functions.

Environmentalists care more about keeping the wild available for human leisure than about the destruction of the animals' habitat and their suffering.
They enjoy the tall trees, clean air, clean rivers and lakes. They value the way nature makes them feel. They believe in saving a forest, because they like to hike in it. They plead for saving a particular river, because they like to fish in it. Environmentalists don’t care about the earth residents, they do it for themselves.

Earth, nature and the environment are notions, concepts, not sentient creatures. They can’t feel. The earth doesn’t suffer, its inhabitants do. It doesn’t care that it is getting warmer and it doesn’t care that the ozone layer is being depleted. Rivers don’t mind that they are being polluted, it’s the residents that mind.

The suffering of every sentient creature is meaningful and all consumption cause suffering. That is the reason to manage a simple and green life. Because destroying the environment is just another form of animal abuse. It is animals’ suffering (humans and nonhumans) that should be the reason and not "harming" non-sentient terms such as the earth and the environment.

So since the earth doesn’t suffer and the rainforests don’t feel pain, actions "for the environment" are actually actions for the residents. But environmentalists protect the environment in a selective and inconsecutive way. The meat eater environmentalist exploits and tortures some species while trying to help others. Environmentalists who consume animal products are irrational and inconsistent. They harm much more than they help.

1. The meat industry contributes 18% of all emissions of greenhouse gasses.
2. Grazing occupies 26% of the Earth’s surface, and feed crop production uses about one third of all arable land.
3. Producing a kilo of feedlot beef takes about 50 times more water than a kilo of Soya beans or rice.
4. 40 calories of fossil fuel are needed to produce 1 calorie of protein from feedlot beef while only 2 calories are needed for protein from tofu.
5. Rainforests are being destroyed at a rate of 125,000 square miles per year to create space to raise animals for food.
6. Factory farms dump into rivers and streams 130 times more fecal matter than the entire human population.

Don’t bother the environmentalists with facts and figures. They are not into rational arguments.
Factory farming is an environmental death sentence, what makes many environmentalists the environment executers. If we can’t even count on the ones who are supposed to be our natural allies, what hope do the animals have?
