Environmental protection

Environmental protection is a practice of protecting the environment, on individual, organizational or governmental levels, for the benefit of the natural environment and(or)humans.Due to the preures of population and technology, the biophysical environment is being degraded, sometimes permanently.This has been recognized, and governments have begun placing restraints on activities that cause environmental degradation.Since the 1960, activity of environmental movements has created awarene of the various environmental iues.There is no agreement on the extent of the environmental impact of human activity, and protection measures are occasionally criticized.Academic institutions now offer courses, such as environmental studies, environmental management and environmental engineering, that teach the history and methods of environment protection.Protection of the environment is needed due to various human activities.Waste production, air pollution, and lo of biodiversity(resulting from the introduction of invasive species and species extinction)are some of the iues related to environmental protection.Discuion concerning environmental protection often focuses on the role of government, legislation and law enforcement.However, in its broadest sense, environmental protection may be seen to be the responsibility of all people and not simply that of government.Decisions that impact the environment will ideally involve a broad range of stakeholders, including industry, indigenous groups, environmental group and community representatives.Gradually, environmental decision-making procees are evolving to reflect this broad base of stakeholders and are becoming more collaborative in many countries.Environmental protection is influenced by three interwoven factors: environmental legislation, ethics and education.Each of these factors plays its part in influencing national-level environmental decisions and personal-level environmental values and behaviors.For environmental protection to become a reality, it is important for societies to develop each of these areas that, together, will inform and drive environmental decisions.Although environmental protection is not simply the responsibility of government agencies, most people view these agencies as being of prime importance in establishing and maintaining basic standards that protect both the environment and the people interacting with it.Outlined below are several approaches to environmental protection that are currently evolving.Further discuion on approaches to environmental protection is included on the pages related to natural resource management, environmental governance andenvironmental law.We live in the world every day.We ea food, drink water, wear clothes, watch TV, use computers and so on.We are producing waste every moment.Generally speaking, there are four sorts of waste.They are material waste, organic waste, inorganic waste and poisonous & harmful waste.Now, we are going to talk about each sort of waste one by one.Material waste: it means the waste of substance or things from which something else can be made.For example, people throw away the used metal products and buy a new one, so the old metal waste accumulates.At last, they become waste.For example, when people finish reading newspaper, the paper will become waste.When the gla is broken, it also becomes waste.Nobody wants to use a broken window or drink with a broken gla or wear a pair of broken glaes.Once it is broken, it becomes waste.The rate of using plastics is increasing day by day.People use plastic bags because they are convenient.When they get home, they throw the plastics way, paying no attention to the environment.The more convenience plastics brings to us, the more plastic waste is produced.This is called “white pollution” as most plastics are white.Some of our products we use every day are made of rubber, just like the tyres and the bottom part of our shoes.It’s true that rubber plays an important role in our life.However, it also brings us some trouble when it has been used for a long time and becomes old.The old tyres become waste because it can’t break down by nature.This is really a big problem.Organic waste: it refers to waste from living things, including waste from animals, plants and people.Some parts of vegetables are thrown away as waste because they don’t taste good.In the past, people cooked their food using burning coal, so there left the burned coal, which is usele, like the thrown vegetables.All this sorts of waste contain organism, so it is called organic waste.Actually, we also have inorganic waste, the opposite to organic waste, including building waste, broken pottery and china, and cinder.The last part is harmful and poisonous waste, such as used batteries, electrical apparatus and medical supplies.Computers and TV sets are one part of electrical apparatus.You see, the old electrical apparatus can set off some dangerous rays and make the soil harder, even damage the under ground water.Mobile phones are as dangerous as computers and TV sets.As we know, X-rays can be used to examine patients, but the X-rays machines are dangerous when they are thrown away without any treatment.They can’t be used to treat the sick, but they still can give off rays.For the normal people, they can be dangerous.So, we must think about this problem.As waste has four sorts, we can sort them into each sort that they belong to.It’s convenient to treat them after they are sorted.Then we can deal with them sort by sort.We have thought out some methods like storing them in order to change them into plant food, or burning them in a huge stove and use the heat to make electricity.For the first way, the change rate is much too low and it may pollute the under ground water.For the second one, of course it’s wonderful if it’s easy to be tried out.But to build such a huge stove will cost too much.Not a good method.Now you see, treating waste is not an easy job.
