Okai:

 

-      az elektromos energia termelése,

-      a haszonállat tartás (hústermelés)

-      a személyszállító és egyéb járművek használata

-      a túlfogyasztás

-      a nemzetközi szállítás

-      az erdők kitermelése,

-      a füstkibocsátás

-      hadviselés (az Egyesült Államok hadereje például a világ legnagyobb olajfelhasználója

       és legnagyobb szennyezője).

-     a Föld légkörében jelentkező üvegházhatás erősödése, amit az üvegházhatású gázok

       koncentrációjának növekedése okoz

-     A globális felmelegedés létezését a kutatók egy része vitatja, többségük azonban ma már

      elismeri, hogy nem csak átmeneti ingadozásról van szó

-     Ha a globális felmelegedés folytatódik, akkor a sarki jég egy része elolvad, ami az

       óceánok vízszintjének emelkedéséhez vezet. A nagy mennyiségű édesvíz megjelenése az

       Atlanti óceánban akár a melegvizű Golf áramlás leállását is előidézheti, ez Európában és

       Észak-Amerikában az éghajlat jelentős lehűlésével járna.

       A globális felmelegedés okozta klímaváltozás tehát nemcsak felmelegedést, hanem adott

       esetben lehűlést is jelenthet.

 

Ide kattintva mindent megtudhatsz, hogy a világ egyes részein mivel,  mennyire szennyeznek
