what's happening to our environment?
Many people believe that the way we live our lives today is having a very damaging effect on the environment.Here are some examples of the kinds of problems we face, followed by some things that we can do to help protect our environment.
THE GREENHOUSE EFFECT
Pollution from cars,factories and power stations is causing harmful greenhouse gases to build up in the Earth's atmosphere. These gases prevent heat from escaping, and as a result our planet is getting warmer. This process is known as global warming.
Global warming is causing the ice at the North and South Poles to melt and sea levels and sea temperatures to rise, leading to serious flooding and violent storms in many parts of the world. In other places, there will be less rain and the land will be turned into desert.

POLLUTION
The biggest polluter today is the car. Exhaust fumes are the main cause of poor air quality, which can make people feel ill and have difficulty in breathing. This problem is especially bad in cities, where the number of cars is increasing every year, causing serious congestion and filling the air with smog. Governments try to improve the situation by encouraging people to use their cars less or buy cars that do not use as much fuel.
All over the world, wildlife habitats are being destroyed. there are many endangered species that could soon become extinct. Rainforests are being cut down so that people can grow crops and feed the world's increasing population. Modern farming methods, for example using pesticides and genetically modified crops, are having a very bad effect on the food chain. killing insects may be useful for growing crops, but it reduces the amount of available food for other animals and birds.

CLIMATE CHANGE
Is also making conditions difficult for some animals. In the Arctic, the ice is melting , threatening the survival of animals such as polar bears.

qhov teeb meem rau peb lub chaw?Muaj coob tus neeg ntseeg tias qhov uas peb nyob tus peb lub neej hnub no muaj nyhuv tsis ua heev rau lub cheeb tsam.Nov yog ib co piv txwv ntawm cov hom teeb meem peb fim, taug kev los ntawm tej yam uas peb yuav ua tau los pab tiv thaiv peb cheeb tsam.LUB TSEV COG KHOOM NYHUVPaug ntawm lub tsheb factories thiab fais fab kev noj yog yuav ua teeb meem tsev cog khoom gases los txoos ua ke nyob rau hauv lub ntiaj teb cua. Cov gases tiv thaiv tshav kub los ntawm escaping, thiab ua peb tus ntiaj chaw lawm rhaub. Txoj kev no yog paub tias ntiaj teb no sov taus. Sov taus ntiaj teb no yog ua rau cov nab kuab tom sab qaum teb thiab South tug rau yaj thiab hiav txwv ntau ntau and hiav txwv muaj peevxwm mus nce, ua rau cov dej nyab loj heev thiab los nag violent nyob ntau qhov chaw hauv lub ntiaj teb. Nyob rau lwm qhov chaw, yuav muaj tsawg tshaj lub ntuj thiab lub teb chaws yuav nres tsis ua suab puam. KEV UA QIAS TUAJTus biggest polluter hnub no yog lub tsheb. Tso pa muaj tus ua ntsiab cua tsis zoo, uas ua rau neeg muaj mob thiab muaj teeb meem rau kev ua pa. Qhov teeb meem no yog phem tshaj nyob hauv lub zos, uas tus nab npawb ntawm lub tsheb muaj coob zuj txhua txhua xyoo, ua rau mob loj congestion thiab sau cov huab cua uas smog. Governments sim los txhim kho qhov teeb meem no los tsis ntshai luaj twg cov neeg siv cov tsheb tsawg los muas tsheb uas tsis txhob siv cov roj ntau npaum. Thoob qab ntuj, cov tsiaj qus yeej yog raug puas lawm. muaj ntau ntau endangered hom uas ua tau sai tu noob. Rainforests yog muab ntov kom neeg yuav cog qoob loo thiab pub rau lub qab ntuj neeg nyob zuj zus. Niaj hnub ua teb kev, xws li siv cov tshuaj tua kab thiab tej loo hloov txhob kaw, muaj ib tug ntxim phem heev rau cov zaub mov saw hlau. uas kab tej zaum yuav pab tau kom koj cog qoob loo, tab sis nws thiaj li tau nyiaj pab khoom noj khoom haus rau lwm cov tsiaj txhu thiab cov noog. KEV HLOOV KEV NYAB XEEBTseem tabtom ua mob tsis yooj yim rau tej tsiaj. Hauv Arctic, cov dej khov melting, tuag tus ciaj sia taus ntawm tej tsiaj xws li polar bears.
