Of course. If you look back in history, there have been environmental and spiritual crises all the time. I think we look at our situation today and think it's the worst it's ever been. During the Reformation, the Inquisition, the birth of Christianity, etc., there were all kinds of spiritual crises for Europeans. We've also had huge environmental crises, too... such as when big volcanoes erupted and sent so much ash into the air that the sun barely got through. About 200 years ago, there was a time called "The Year without a Summer" because the volcanic ash blocked out the sun. However, I do believe that with nuclear bombs, we have the capability to do more harm to the earth than at any other point in history. But even at that, meteors have struck the earth and done incredible harm to the environment. Scientists think a meteor hit the earth and killed off all the dinosaurs.

Polution, and destroying trees and stuff. Basically living, destroys the envirment.

Both. As non-sustainable practices begin to have more and more consequences we will be forced to find alternatives, and often will not find the alternative in time to prevent significant suffering. In some areas we may have enough foresight to change before the impact is felt. I am encouraged to see more and more wind power being installed, both on land and on ocean based platforms, but at the same time I am discouraged to see people choosing to drive large SUV's which will have a negative impact on the future. In some areas reforestation is taking place, where 100 years ago there was deforestation. This is encouraging and is simply the result of changing economic use. I have also been encouraged to see negative population growth in the most industrialized countries; this suggests the present stresses on the planet may be relieved.

1)The damage caused by the petro chemica smog.\n2)The human tragedy that strike at the lives of the people like the Bhopal gas tragedy too grave to be compensated by money.\n3)Urban poverty.\n4)The evils of industrilisation were well recognised even by the intellectuals of the 19th Century, like Ruskin, Arnold &Carlyle. It destroys the family of the industrial workers and their soul.

1) Farming can cause soil erosion: \ne.g. Deforestation removes roots holding soil and allows extensive wind and water damage. \n\n2) Farming causes desertification: \nThis is when a desert gradually spreads to the surrounding areas of semi-desert, making them true desert! \n\n3) Chemical pollution and habitat destruction are major problems: \nCareless use of fertilisers pollutes rivers and lakes, making them green, slimy and horrible. \n\n4) Irrigation can cause environmental problems:\ncreating dams involves flooding large areas. Wildlife habitats are destroyed and people have to be resettled! \n\nHope I helped!

There is this really great book called EXTINCTION by the Ehrlichs(?)...which starts out with a beautiful analogy about the environment. It starts off with this guy who removes rivets (screws) from an airplane wing so that he could sell them for profit. Each rivet/screw represents a unique species that plays an important role in our ecosystem. The loss of each one has an adverse effect on the whole structure. It is true that such effects may or may not have an immediate recognizable effect on us but that does not mean that it is not happening. Also, we humans, have proven that we are really self centered that we do not recognize the damage that we are doing unless it hits us in the face. There are countless examples of chain reactions in the ecosystem due to a loss of an integral species. For example, (although I am no longer certain about the details) due to the misuse of a pesticide by farmers in rural Peru, an outbreak of more resistant  pests evolved. The farmers in reaction started to use more pesticides which affected the other species that naturally feed on and control these pests. The situation got so bad that it escalated to such an extent that cats which controlled the rat population died out because they got the higher dose of the poisonous pesticide in their system. Finally, (believe it or not) they had to fly cats to the area and dropped them from helicopters...thus it did rain cats that day in Peru.

Environmental effects\n\nModern mining companies in many countries are required to follow strict environmental and rehabilitation codes, ensuring the area mined is returned to its original state, or an even better environmental state than before mining took place. Past mining methods have had, and methods used in countries with lax environmental regulations continue to have, devastating environmental and public health effects. The result can be unnaturally high concentrations of some chemical elements over a significantly wider area of surface. Combined with the effects of water and the new 'channels' created for water to travel through, collect in, and contact with these chemicals, a situation is created where mass-scale contamination can occur.\n\nEnvironmental issues can also include erosion, formation of sinkholes, dangerous sites such as deep holes in child friendly communities, destruction of the environment, loss of biodiversity, and contamination of groundwaters by chemicals from the mining process and products.\n\nSome examples of environmental problems associated with mining operations are:\n\nAshio Copper Mine, Ashio, Japan was the site of substantial pollution at end of the nineteenth century \nBerkeley Lake, an abandoned pit mine in Butte, Montana that has filled with water which is now acidic and poisonous. \nScouriotissa, a copper mine in Cyprus that has been abandoned. Contaminated dust blows off this site. \nTar Creek, an abandoned mining area in Picher, Oklahoma that is now an Environmental Protection Agency superfund site. Water in the mine has leaked through into local groundwater, contaminating it with metals such as lead and cadmium. \n\nAlthough such issues have been associated with some mining operations in the past, modern mining practices have improved significantly and are subject to close environmental scrutiny.

Pollution can cause the following harms:\n1. Dust particles and smoke particles deposit themselves in the lungs and cause respiratory problems.\n2. Carbon monoxide react with the red blood cells to form carboxy haemoglobin. Then red blood cells loose the capacity to carry oxygen.\n3. Chlorofluorocarbons destroy the ozone layer and this in turn can cause skin cancer.\n4. Sulphur dioxide and nitric oxide dissolve in water to form acid rain. This acid rain destroys buildings and damages crops and trees.\n\nWell,that's all i have.Hope this bit of information helps you to get through your homework.\nAll the best.

I have heard it as "for every action, there is an equal and opposite reaction" As for people and environment.  Someone cuts down a forest- what happens? Soil biodiversity changes, animal species in that area change, CO2 consumption in that area decreases.\n   People put more black top up- absorbs and reflects heat warming the earth's surface more. There are a ton of examples, I am not sure what you are looking for specifically.
