Humans are destroying Earth.

           In this discussion i will  use the film" The Eleventh Hour " to prove that humans are  destroying the planet earth, hence they will cause a catastrophic demise of  themselves. The film clearly states that scientists have agreed that global warming is  a result of greenhouse gases CO2 of which fossil fuel is the leading comtributor.According to  Richard Heinberg, the environmental system is polluted ,by the burning of  oil, especially in poor neighbourhoods and more people are contractimg asthma.as a result of the breathing the polluted air.
            The destruction of  trees  in many countries for lumber without replanting also contributes to global warming. For the leaves are the main  source of intake of carbon dioxide.Therefore the earth is getting warmer with the gas  trapped in the air. As a result there is a change in the weather pattern universally. Some countries have excessive rainfall while others are having drought.This in turn causes destruction to crops and lost of livestock for which humans depend on for consumption to survive.

                The  pollution problem is a burning issue, currently in classdiscussion ,Concentrated Animal Feeding Operation(CAFO) is also contributing to water and air pollution. The urine  and feces af animals are let into rivers which destroys the environment.A classical case is Tyson  Foods of Arkansas, accorging to classdiscussion.

                On one hand industrilizations are moving forward rapidly and destroying the environment while on the other hand humans are suffering from the effect of  such  actions which will eventually lead to an extinction  of humans, because if the environment is unhealthy,living things will subsequently suffer and die.
