what is nature? it's everything that exists in the world independently of people, such as pants and animals, earth and rocks, and the weather.

now more and more people are focusing on the nature. it is no doubt that the nature is important to every human being. no nature, no life. because of the supplies of the nature, we have lived happily for a long time. and we started to gain every thing available from the nature. and this lasted so long a time. today, people have discovered that the nature around is getting worse and worse.

what is threatening the nature? air and water pollution, overharvesting of plant and animal species, overpopulation and so on. overpopulation is the biggest source of pollution. let's take overpopulation as an example.

what does overpopulation feel like? when we move slowly through the city in a tazi. when we enter a crowded slum district. when the temperature is high and when the air is thick with dust and smoke. the streets are crowded with people. the streets seem alive with people. people eating. people washing. people talking. people sleeping. people visiting each other, arguing and screaming. people relieving themselves. people pushing their hands through the taxi windows, begging. people leading animals. people, people, people, people. as we drive slowly through the crowd, sounding the taxi's horn, the dust, heat, noise and cooking fires made it like a scene from hell! i admit, frightening.

to the nature, overpopulation is a big problem. more people, more pollution. and the big population is threatening the nature every second.

the rapid rise in world population is not creating problems only for the developing countries. the whole world faces the problem that raw materials are being used up at an increasing rate and food production can not keep up with the population increase. people in rich countries make the heaviest demands on the world's resources, its food, fuel and land, and cause the most pollution. a baby born in the united states will use in his lifetime 30 times more of the world's resources than a baby born in india. unless all the countries of the world take united action to deal with the population explosion there will be more and more people fighting for a share of less and less land, food and fuel, and the future will bring poverty, misery and war to us all.

for most of the developing countries, it is a good idea to control the population growth. for example, china has carried out birth control for years. and this plan has a great effect on the world population.

if the population continues to increase, if the air and water continue to be polluted, if we don't do something to protect wild-plant and wildlife species will be declining. species and biological communities have difficulty adapting to change. economic opportunities and the quality of life of future generations are also put at risk. by protecting nature, we protect ourselves.

let's unite together, hand in hand we stand all across the land.

we can make this world in which to live. hand in hand. control the population growth. take good care of our nature.

demand for graduates in the uk with skills related to sustainability is booming. academia is waking up to the need to train specialists in green architecture, chemistry and engineering.

dean millar founded the worldsquo;s first ever bsc course in renewable energy at exeter university after working as an industry consultant.

he said: a lot of companies were complaining that there was a lack of bright young people suitably trained to work in the renewables business.

now his course has around 90 students learning the ins and outs of biomass, tidal, solar and offshore wind power.

their career prospects are incredibly bright. employment opportunities are not just limited to the energy sector, but segue into the regulatory and, increasingly, investment sectors as well.

the big boys are moving in. the returns to be had are significant, especially in terms of wind development, said millar. financial firms need expertise across the board so they can make sensible investment decisions.

students on york universitysquo;s mastersquo;s course in green chemistry are ideally placed to take advantage of the growing demand in industry for graduates with waste minimization skills.

professor james clark is founder of yorksquo;s green chemistry centre for excellence and the worldsquo;s leading green chemistry journal, green chemistry. he said: we are now talking to producers of automobiles, electronics, furniture and pharmaceuticals, people who need to use chemistry but donsquo;t think of themselves as chemists.

as waste production legislation becomes increasingly strict, the traditional emphasis on making as much of a chemical as possible is shifting towards minimizing the waste that process creates. a lot of chemicals are made from petroleum, but we are developing sustainable ways to make carbon, typically from biomass such as dead plants and trees, said professor clark.

all of last yearsquo;s graduates quickly found employment, some receiving multiple job offers in a variety of different fields.

li li, a 26-year-old chinese postgraduate student, graduated from york in 2006. she said:

i hadnsquo;t heard about green chemistry in china. it was a new area and i was curious. now the government back home needs people who know about these principles.

deep in the heart of wales, 400 students at the centre for alternative technologysquo;s (cat) graduate school of the environment are busy designing and building everything from high insulation wood housing to wind power turbines. with energy costs rising, building firms are increasingly looking to minimize the energy wasted heating and lighting homes, a service cat students are well-equipped to provide.

a new institute is being built to meet the burgeoning demand for places and a distance learning facility will be launched next september so foreign students can complete cat courses from home.

the expertise being taught on these courses is essential to a continually expanding range of companies and government authorities. yet there is a larger goal at stake; the students are at the forefront of the battle against climate change. in the words of dean millar, if wesquo;re going to save the planet, we need to start turning these people out in big numbers.

we live in the world every day. we eat 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 glass is broken, it also becomes waste. nobody wants to use a broken window or drink with a broken glass or wear a pair of broken glasses. 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. itsquo;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 cansquo;t break down by nature. this is really a big problem.

nowadays, the environmental protection is becoming one of the most important issues in the world. being one of the members of our society, what shall we do to protect the environment?

first, stop using plastic bags, boxes and bottles. stores should be required to use the bags, boxes and bottles which are made from paper.

secondly, more and more trees and flowers should be planted to keep our surrounding clean. people must be required to plant plants around their houses and work places.

finally, we must control the pollution by law, according to which, polluted water and air exhausted from factories should be forbidden.

these are some of the measures that we can take to protect our environment and they are not hard tasks for us. remember, the earth is the only planet we could live at present.

since the first day, bnbm has paid more attention to protect the environment as its social responsibility, by developing green building materials, producing green products and creating green enterprise. according to the spirit of "from the nature, for the nature and return to the mature", bnbm has tried its best in developing new technology and improving equipment to reduce the pollution.

we have only one earth. but now,the environment becomes worse and worse.

as you know,there's no enough clean water for people. so many of them lose their lives because of water. in a lot of countries, people have to cut trees for living. so there's nothing to keep water from running away. also we have polluted the land, the river and the air. so we have to face more and more floods and droughts .

it's time that we must do something useful to protect our environment. we can plant trees and take good care of them. we can save the water and ask our parents to do so. we can't throw any litter onto the ground and we should collect them for recycling.

if we take good care of our earth today,it will be more beautiful tomorrow.
