Technology is defined as the collection of techniques,methods or processes used in the production of goods, services or in the accomplishment of objectives. some people believe the booming development of technology resulted in various environmental problems. in my opinion, technology is the way to solve these problems.
a thousand years ago,people used stone tools to make fire by rubbing a stick with a stone. afterwards,they know about " shame" so they made clothes from leaves, animal skins and turned caves into shelter. later, human had an abundant supply of foods and the discovery of metal, step by step,changed the whole civilization. from that day on, people used metal in every areas: transportation,energyy,agriculture and so on. this shows that the development of technology is envitable and plays an important role in human's living
nevertheless, industrial arts also has bad impacts on everyday life. tons of poison smoke are exhausted from factories which cause acid rain, carbondioxide. not only does it dangerous to people's health but also spoil ozone layer, makes temperature higher and higher. industrial trashes are thrown into seas, lakes, rivers causing bad pollution. So, is this technology's fault or the expansion of human life? we use technology to develop from stone-age civilization to industrial civilization without caring of environment nor ecosystem. and we are paying flor this
however, we can change the situation before it's too late. many organizations such as UNEP, AFEO are doing postivlely in changing society. they invented machines which can clean the air, trees which produce more oxygen and the appearance of solar energy have brought a new decade for factories, companies. As new energy sources like wind, water or solar are becoming poplular, the factories no longer have to use colar or gas energy to maintain their activity. technology is also the solution of transportation and the government are investing more money on bus and underground subway to decrease the rate of using motorbikes or cars. each bus can hold up to 150 people and the subway declines exhaust fumes in the air.moreover, these public vehicles are cheap, convinient and reduce traffic jam. many rivers, lakes are in bad polluted condition so the recovery costs so much money and time. industrial arts nowadays only solve a part of the problem, reuse drain water instead of pouring directly into river. there is a kind of fish that eats trash so scientists hope it is a cure for the situation. our soil is polluted as well,because of chemiclas that people use in agriculture can cause poison, contaminate the soil.what can we do today is supply necessary ,organic substances to improve the ability of holding water and loosening capability of soil
in conclusion, technology will change the face of society
