Air Pollution

  The earth's atmosphere is polluted naturally by sandstorms and the dust and gases from volcanoes. But the most serious kind of air pollution comes from people. Factories, power stations, and vehicle exhausts pump harmful gases into the air, contributing to global warming, causing acid rain, and destroying the ozone layer. On a much smaller scale, air pollution causes all sorts of breathing problems. There are no simple solutions to air pollution, but people could reduce air pollution by saving energy and reducing harmful emissions from vehicle exhausts and power stations.
  When a volcano erupts, dust is blasted high above the troposphere and may take weeks to be earned around the world. It is above the weather zone, so cannot be washed out of the air by rain. It will eventually fall to the earth after a few years.
Air pollution is at its worst over big cities where millions of people live, work, and travel about in cars, buses, and trucks. Factory chimneys can be fitted with devices to cut down air pollution, but this is expensive. If better public transport and cycle lanes were available in towns and cities, people would be less likely to use their cars, reducing the overall amount of pollution.
  Smoking cigarettes adds to the general levels of air pollution as well as damaging our health. Cigarette smoke contains chemicals that can cause cancer, a gas which stops oxygen being taken into the blood and a substance called nicotine which raises blood pressure and makes the heart beat faster. No-smoking areas cut down on this pollution and save non - smokers breathing in other people's cigarette smoke.



Water Pollution

  Humans use enormous quantities of water. Not only do we drink it, we use it to wash and bathe, We irrigate farm crops and gardens. We use it to flush away waste in the sewage system. Flowing water provided the first source of energy to power machines. Today's factories still use water to make things, or sometimes just to cool machinery. Hydroelectric power is an important source of energy in some countries. We need for water in reservoirs —but this may disturb a river's flow. We sink bore holes but these may dry out the land and stop spring flowing. Many human activities leave water dirty, and sometimes full of unwanted and dangerous chemicals. How to stop this pollution is one of the Invest problems we now face.
  POLLUTING WATER Detergents and poisonous chemicals are an obvious danger to water. But even chemicals that make things thrive, such as fertilizers, can create problems. If they run off the land into water they can make tiny water plants grow too well. These may use up all the oxygen in the water.
  ACID RAIN Power plant produce sulfur dioxide and nitrogen oxides when they him coal. If these are not filtered out, they are pumped into the air from huge chimneys. Carried by wind, polluted clouds can make rain very acidic hundreds of miles away. This rain can kill trees, damage other plants, and make water too acidic for fish. Acid snow can also damage the countryside.
  DANGER IN THE FOOD CHAIN Some substances that are used to control pests break down soon after they are used. But some do not. and these may be passed up die food chain to animals which are not the original target of the poison. The poison can build up to harmful levels in animals at the top of the chain.


Recycling paper

  After two decades of dire predictions that our "fragile" planet is being stripped, we face a new problem: our mounting supplies of recycled goods far exceed the demand. Yet, as the costs of health, education, and welfare programs soar, states are mandating costly, unnecessary, and impractical recycling programs. With plenty of relatively inexpensive landfill space, states didn't need to pay "more than $250 million to subsidize recycling" in 1994. Contrary to popular beliefs, paper recycling doesn't save our stately old forests, for "87% percent of our paper comes from trees specifically planted for that purpose." I don't want to discourage anyone from recycling whenever it can help save resources without causing greater problems. But when noble intentions cause more harm than good, we had better learn the facts and do what is best. Even the U.N.'s Rescue Mission Planet Earth, so full of globalist propaganda, brings a bit of wisdom through Rauno Laithalainen, a Thai Forestry Worker. Her warning is for all of us:
  Recycling, that great environmental savior, may not be as beneficial at it seems. In Thailand, all paper is recycled. The old paper has to be washed to get rid of all the ink and this causes heavy metals to pollute [our] rivers. The poison gets into the fish and the surrounding countryside. The best thing is always to plant fresh trees.



  Interviewer: Today, I'm interviewing nine-year-old Alex about her feelings on how people can help save the environment. So, Alex, how can we save the environment?

Alex: By saving water.

Interviewer: Well, how can we do that?

Alex: By not using too much water when we wash dishes, take a bath, and when we do other things, like watering the plants outside.

Interviewer: Oh, I think I can do that. What else?

Alex: When drinking or eating something outside, you should keep the garbage until you find a trashcan to put it in because littering makes our planet dirty. Do you like seeing trash all over the ground?

Interviewer: No, I don't. Do you have any final suggestions?

Alex: Yes. We shouldn't waste paper because trees are being cut down to make the paper. By recycling paper, we save the forests where animals live.

Interviewer: So, how can children recycle paper, I mean, everyday?

Alex: Well, for example, when I was in kindergarten, I used to save the newspapers so that I could things make out of them, like paper trees, instead of just throwing them away. Now, the children in our neighborhood collect newspapers once a month to take them to a recycling center.

Interviewer: That's great. Well thanks Alex for your ideas.


A Strategy for Saving the Earth

Dear Jasper:

  It's clear that our environmental problems are so huge that they will only be solved by everyone doing their part -- every person, group, community, government agency, company, etc. And quickly! How can we even reach all of them in time? The same way that the body gets blood to every cell. The same way that a plant gets food to every part (although I just read that we don't really know how that is!). Every person must exert pressure in every direction, passing information and resources to whoever will accept it (without damaging our own lifestyles, I insist! -- in fact, I think that this process, executed properly, can be as joyous and energizing as any other part of life).

  We need therein to minimize waste. On any given issue, there are two kinds of people -- those profiting from the status quo, and therefore not open to new information (e.g., most politicians, the wealthy, and the would-be wealthy (they are called "Republicans")), and the majority (especially children) who are open to learning. It is a waste of time to try to influence the former, unless you also have a big stick or a choke-hold on their wallet. We need to reach, as quickly and efficiently as possible, the individuals and groups that are receptive, and get them to help us.

  I just sent a mailing of 68 packages of my recent writings, your BLF flyer, and excerpts from Regreening the National Parks to groups in the Alliance for a Paving Moratorium. Every new fact that I find that can serve as ammunition in the war against roads, I Xerox and send to everyone I think might be receptive to it. Every letter I write, I try to make as general as possible, so that I can use it in as many settings as possible. I make copies and mail them to friends. I put them on the Internet and send them to "the world". Thousands of people on thousands of computers around the world read them and, hopefully, pass them on or internalize the facts and ideas. Sometimes I also send them to newspapers, but they are not often printed (except in the Berkeley Voice, a rare paper that truly practices Freedom of Speech), so this can be a waste of time.

  While I am resting, doing my weekly hike in the woods, or writing my next letter, I want people all over the world to be helping spread the essential facts and attitudes that will pull "humanity" out of its slide. If I were to try to do it all myself, the speed of the process would be proportional to my energy (i.e., linear) and very limited in imagination. By "multi-processing", it expands at geometric speed and benefits from the energies and multifarious viewpoints of thousands (millions?) of people. I don't have all the answers, nor does anyone else.

  The law can help, but it isn't the whole answer. Political action can help, but it also can be a giant waste of time, when people we elect on one platform are bought by "big business" and begin pushing a different one. Gentle persuasion has its place, but we also need people who aren't afraid to tell the unvarnished truth. In short, we need all the help we can get! The final result, I foresee, is a situation where the politicians who won't hear the truth from me now will be surrounded by friends who have all been "converted". Just as racial slurs are now socially unacceptable, and public smoking is becoming so, I foresee that it will soon be unthinkable for anyone to suggest building or widening a road.

  We will win, because we are right. It is inevitable. Oil resources are finite. Only in mathematics is anything infinite. The only thing we need to do is speed up (catalyze) the process. It isn't even very difficult. Most people, I have found, are open to information and, once we get their attention, and they look at the facts, agree with us. But we have to find the most responsive ones and get them to integrate our agenda into theirs.

  Example: six years ago when I began fighting highway construction, I met with the local bicycle group and asked them to help me. They refused. They said they didn't want to get involved in a hopeless struggle. They didn't see my goal as a way to achieve their own goals (or as I would say, the only way to achieve their goals!). Now, all that has completely changed. Bicyclists around the world are on the cutting edge of the "road ripping" movement. (Ironically, some of them are also leading the charge to expand man's domination of wilderness, via "mountain" bikes -- an oxymoron, if ever there was one.)

  I see our job as extending that revolution to groups working for animal rights, forest and habitat preservation, public transit, rail, air quality, water quality, native peoples, women, children, the homeless, ecocities, sustainable communities, population reduction, noise reduction, civil rights, etc. Via conversations, conferences, the Xerox machine, the computer networks, the mail, schools, universities, perhaps even the traditional media (although most of them are highly resistant to dealing with the truth).

  Instead of beating our heads against brick walls such as politicians and businessmen, we should use our real forte -- the powers that haven't yet been taken away from us: our freedom of speech, our freedom of association, and our freedom to spend our money where we choose.

  What should that agenda be? Plants can't protect themselves from us, and are the basis of all life. They obviously need to be given first priority. Then animals, who also can't protect themselves from people. Extinctions, of course, are unacceptable. Then I would suggest native people, children, and women. Or? Of course, this automatically precludes more roads. Agreeing that extinction is unacceptable, I believe, entails all of the rest of our goals -- sustainable communities, bicycle-friendly cities (but not parks!), the works!
