CE PROBLEME ECOLOGICE FAC FATA LUMII NOASTRE?

Ca vitori cetateni ai lumii suntem preocupati ca viata noastra sa se desfasoare in conditii normale, sa nu fie privata de neajunsuri, sa traim intr-un mediu curat, inconjurat de toate frumusetile naturii.Tocmai de aceea in ultimii ani problemele ecologice au captat atentia lumii, caci resursele divin tot mai limitate si toata lumea se gandeste ca urmasii nu vor mai avea cu ce sa se bucure.Astfel s-au desfasurat campanii de reinnoire a resurselor, de descoperire a unor substituenti, de protejare a resurselor ramase si nu in ultimul rand de economisire a acestora.

Astfel in una din serile acestei veri se prezenta la televizor o campanie prin care toata lumea trebuia sa uite de existenta energiei electrice pentru o ora, astfel realizandu-se o mica economie, toata popuatia globului fiind indrumata sa scoata din prize chiar si aparatele electronice pe care nu le foloseste, pentru ca si atunci cand sunt in priza ele consuma energie .Tot legat de economia energiei electrice lumea este indrumata sa foloseasca becuri fluorescente care au un consum mai mic si o viata mai lunga decat cele incandescente. S-a inventat detergentul pentru apa rece, pentru a nu mai folosi energie in incalzirea apei, ca si aparate electronice si electrocasnice cu consum mic de energie. Exista companii care ofera energie solara sau eoliana. De aceasta optiune nu poate beneficia foarte multa lume, dar este o modalitate de a ajuta pentru un mediu mai curat.




Deoarece oamenii necivilizati arunca ambalajele pe strazi, in parcuri , in paduri la iarba verde, si nu in spatii special amenajate cum ar fi normal, a pornit o noua campanie prin care se doreste renuntarea la ambalajele de plastic care nu sunt biodegradabile , si utilizarea sacoselor de hartie care sunt mai rezistente.La ghena de gunoi s-au amenajat containere speciale pentru colectarea plasticului, hartiei, reciclarea lor ducand la o economie foarte mare de resurse si energie.

Un alt domeniu in care se doreste o campanie de economisire este cel al hartiei si lemnului in general. Pentru ca este afectata clima din cauza defrisarilor, pomul de iarna trebuie inlocuit de brazii artificiali, iar parfumul natural de brad poate fi adus in case prin odorizante speciale. De asemenea exista in tara mai multe ziare care utilizeaza hartia ecologica, reciclata pentru ca este mai ieftina si mult mai sanatoasa pentru mediu, adica mai putini copaci vor fi sacrificati. Pentru obtinerea unei tone de hartie pentru imprimanta sunt sacrificati 24 de copaci, iar pentru o tona de hartie de ziar, cad 12 copaci. Suntem indrumati sa plantam macar un copac in propria curte, in curtea scolii sau in locuri din apropierea padurii deoarece in timpul vietii, un arbore poate absorbi tone de dioxid de carbon, iar in zilele calduroase, umbra oferita de un copac nu poate fi comparata cu aparatul conditionat care este si consumator de foarte multa energie.

Prin toate aceste masuri vedem cum problemele ecologice isi gasesc solutii in lumea in care traim, insa totul va merge bine numai cu implicarea noastra de mici copii, prin educatia ecologica, prin respect fata de natura si iubire de frumos caci nimic nu se compara cu o padure privita in fiecare anotimp(verde crud, multicolora sau alba) sau un rau curat de munte atunci cand mergem la iarba verde.

Si natura are sufletul ei si trebuie sa o ajutam sa fie mereu infloritoare!

What ecological problems can be solved nowadays?

As future citizens of world we are preoccupied with our lives unfolding in normal conditions, not being deprived of common goods, us living in a healthy environment, surrounded by all the beauties of nature. Because of this, in the last couple of years, the ecological problems have attracted the world's attention, since the resources are getting more limited and everybody thinks that our offspring will not have what to enjoy.  Therefore, there have occurred campaigns of renewing the resources, of discovering substitutes, of protecting the resources that have remained, and last, but not least, of saving them.

Thus, during one evening this summer, a TV campaign was presented, in which everyone should act for an hour, as if electrical power never existed, thus providing a small saving.  The entire population was persuaded to unplug even the electric devices that were least used, because they use power when plugged.  Pertinent to saving electrical power, the population is urged to use the fluorescent bulbs, which have a lower consumption and a higher durability rather than the incandescent ones.  A detergent for cold water was developed, so that one wouldn't use energy to heat the water anymore, similar to electronic and house devices with low energy usage.  There are companies that provide solar or wind energy.  Not many people can benefit from this option, but it is a way to help for a healthy environment.

Because uncivilized people throw wrappers on the streets, in parks, in the forests, while on picnics, and not in special designed spaces, as it should be, a new campaign started; its main goal is to give up on plastic wrappings, as they are not biodegradable.  Instead, one should use paper bags, which are more resistant. Near the garbage containers special containers were placed, for individual collecting of plastic, metal and paper, their recycling leading to a great saving of resources and energy.




Another area in which a campaign of saving is desired, is that of wood and paper, in general. Because climate is affected due to wood clearing, Christmas trees should be replaced by artificial firs, and the natural odour of the natural fir could be sensed in houses through special air freshners. There are also many newspapers that use ecological paper that is recycled because it is cheaper and healthier to the environment, meaning less trees will be cut down. To obtain one tone of printer paper, twenty four trees are cut down, and to get one tone of paper for newspapers, twelve trees are cut down. We should plant at least one tree in our own courtyard, in the schoolyard or in places located near a forest, because during its existance, a tree absorbs tones of carbon dioxid and during warm days, the shadow of a tree cannot be compared to an air conditioner, which is, among others, a really great energy consumer.

All these measures lead to solutions to present ecological problems, and these solutions have roots in our childhood education, in the ecological education, in our respect towards nature and beauty.Nothing compares to a forest seen in every season: green, copper-coloured or white, or to a a clean river seen during mountain escapes.

Nature has its own soul and we should do our best to make it flourish!
