Many environmental problems are currently occuring.Among these problems are polluted waters and felling of tress,precious topsoil has been replaced with poison and clean air is now filled with dirt,filth and danger.Genetic engineering has destroyed plants and animals.Furthermore,changes in the topography of the land have led to destructive landslides and floods.As a result of these environmental problems,less oxygen is produced as tress continuee to be felled,water will become undrikable and deadly new disease will emerge.Inevitably,humans will fall sick as a result of the overuse of chemicals in agriculture,food production and industrial process.
