2 Natural Disasters and Environmental Problems Volcanic eruptionDrought
3 MAIN ENVIRONMENTAL PROBLEMS Air pollutionDestruction of the ozone layerGreenhouse effectGlobal warmingWater pollutionDeforestationHuntingOverfishingLitter/rubbish
4 CAUSES gases from factories. car exhaust fumes/traffic fumes. increase in the amount of carbon dioxide and other gases being released in the atmosphere.dumping industrial waste in rivers and seas.dangerous chemicals from factories being poured into streams, rivers and lakes.people in poor countries are destroying jungles and forests because they need farmland to feed their families.forests are being burnt or cut down by logging companies for profit.lots of animals are killed for body parts (skins, horns, tusks, etc.).production of too much packaging and food waste.
5 EFFECTS acid rain (damages to trees, lakes and buildings) smog breathing problemscancer riskchange in world’s climatesea and oceans levels risingextreme weather conditions (floods, tsunami, etc)fish diestomach illnessesdestruction of the rainforestdestruction of natural habitatslots of animals in danger of extinctionlots of animal and fish are disappearing (endangered species)dirty streetsdiseases
6 Possible Solutions reduce gases emitted from factories use public transport instead of carsreduce chemicals areosol sprays and fridgesuse alternative sources of energylimit use of chemicals in industryfine factories which pollute streams, rivers and lakesgive financial support to poorer countriesencourage countries to control the number of trees that are burnt or cut downstricter laws and harsher punishments for legal hunting (poaching) and fishingmore protected national parksencourage recycling
