Transcript of Environmental Problems

E NVIRONMENTAL P R O B E M S There are 4 major Environmental Problems 1. Environmental Crisis 2. Emergency Crisis 3. Population 4. Housing Dilemma The world is facing a very serious environmental crisis. Key environmental problems include air pollution, the destruction of the ozone layer, vast quantities of toxic waste, massive levels of soil erosion, the possible exhaustion of key natural resources such as oil and coal, and the extinction of plants and animals on a scale not seen since the death of the dinosaurs 60 million years ago. We think that this crisis is likely to have catastrophic effects in the future. Even today, the negative effects of the crisis are evident in the form of growing deserts, increased rates of cancer, and the loss of plant species which could hold out cures for diseases for diseases such as AIDS etc. An emergency is a situation that poses an immediate risk to health, life, property or environment. Most emergencies require urgent intervention to prevent a worsening of the situation, although in some situations, mitigation may not be possible and agencies may only be able to offer palliative care for the aftermath. A crisis (from the Greek - krisis; plural: "crises"; adjectival form: "critical") is any event that is, or expected to lead to, an unstable and dangerous situation affecting an individual, group, community or whole society. Crises are deemed to be negative changes in the security, economic, political, societal or environmental affairs, especially when they occur abruptly, with little or no warning. More loosely, it is a term meaning 'a testing time' or an 'emergency event'. A population is all the organisms of the same group or species who live in the same geographical area and are capable of interbreeding. In ecology the population of a certain species in a certain area is estimated using the Lincoln Index. The area that is used to define a sexual population is such that inter-breeding is possible between any pair within the area and more probable than cross-breeding with individuals from other areas. Normally breeding is substantially more common within the area than across the border. One of the social problems bred by capitalism, manifested as a particular form of housing need. With the growth of the urban population and the transformation of a dwelling into a commodity, there is a sharp deterioration in the working people’s living conditions and a huge rise in apartment rent. The housing problem is exacerbated under imperialism. The process of monopolization and the strengthening of the influence of bank capital, which operates in the housing economy mainly in the form of mortgage credit, cause high monopolistic prices for apartments. Only one-third of total apartment rent is expended on maintenance; the rest is used to enrich landlords, landowners, and bankers.
