臭氧层的破坏

It took the reality that CFCs were destroying the sensitive but protective

ozone layer to encourage large chemical companies to begin a gradual phase-out

of these substances, even when scientists had already discovered the terrible

effects of the chemical combination. To slowly stop usage of such obviously

dangerous substances is not enough, for even with current conditions, it is

estimated that the damaged ozone layer will require at least 100 years repairing

itself. In the interim, we are risking danger to the food chain, global warming,

and increased cases of skin cancer. Rather than risk these catastrophes, we

should call for the immediate phase-out of CFCs, as well as to improve energy

usage, plant trees, and curb the population explosion as supplemental methods to

improve the environment.

空气污染物对健康的影响

With the great concern surrounding the destruction of the earth‟s atmosphere

due to air pollution, the immediate and direct harm caused to the human body is

often over-shadowed. While many are aware that our careless use of hazardous

chemicals and fossil fuels may leave the planet uninhabitable in the future,

most overlook the fact that they are also causing real damage to our bodies at

this moment. Such pollutants cause damage to our respiratory system, leading to

the fluctuation of the life span of an individual depending on a number of

conditions. Amongst these conditions are the individual‟s specific geographic

location, age, and life style.

In order to understand how air pollution affects our body, you must

understand exactly what this pollution is. The pollutants that harm our

respiratory system are known as particulates. Particulates are the small solid

particles that you can see through a ray of sunlight. They are products of

incomplete combustion in engines (example: automobile engines), road dust, and

wood smoke. Billions of tons of coal and oil are consumed around the world every

year. When these fuels burn, they produce smoke and other by-products into the

atmosphere. Although wind and rain occasionally wash away the smoke given off by

power plants and automobiles, much still remains.

燃料对环境的影响

As time passes, an increasing amount of capital will be spent on fuel and

energy to produce goods. It is a long-term incentive to find alternative energy,

such as solar energy, that will not deplete at the rate fossil fuels do, and

after an initial investment, take very little monetary capital to maintain. This

move must go hand-in-hand with current technology, in part because technology

depends on its successful integration into the existing system. It is also

important to achieve integration among major economic sectors, such as

agriculture, auto manufacturing, and the oil industry. If changing technology is

incorporated into current production methodologies, large capital expenditures

can be minimized or folded into the overall business plan in a sensible way.

全球化贸易和交通对环境的影响

As more global corporations take over most of

the aspects of farming, local resources and labors of small farms are

decreasingly vanishing. This caused the people to buy and eat food that are

grown overseas instead of the local areas, thus, causing and encouraging the

amount of international transportation.

The transport division is a significant contributor to local air pollution,

noise annoyance, intrusion to landscapes, congestion and high fatality rates.

Transport also damages the global environment. It is contributing to two main

global environmental problems, which are the greenhouse effect and the depletion

of the ozone layer. Even though the effects of globalization contributed to many

environmental defects, some may argue that free trade will avoid the efficiency

losses associated with protection. It will reinforce economies of progression,

and entrepreneurs are provided with an inspiration to seek new ways to export or

compete with imports, a situation that offers more opportunities for learning

and innovation. Their belief is that trade liberalization will likely have a

positive effect on the environment by making the contribution of resources more

efficient, promoting economic growth, and increasing general welfare.
