It is the most common question among the people of world , what are the negative changes appear on environment some years later? By seeing the destruction and declination of natural resources , we can say we have to faced many problems in future. Earth is the common habitat of living creatures , if earth is affected then all living beings also faced this problems. Human is responsible for all the destruction of environment . His activities are against with environment . He is the integral part of this planet and it is human responsibility to care the earth and other living creatures existing on earth . Human only know to use the natural resources for his daily requirement but forget his responsibility towards nature .
If the process of destruction and declination of environmental resources is Continuous , there are many negative effects appears on environment directly or indirectly . If human beings not aware about conservation and protection of environment and other living resources , human races will also be in danger . After some years , there will change in everything . The population will increase rapidly , there is everywhere polluted , increase in temperature of earth , due to the deforestation , there will be increase chances of soil erosion and flood . The lifestyle of human beings is unhealthy and many disease will appears day by day . There will be decline of biodiversity in huge amount . There will increase in infrastructure development and technology in planet as well as the process of destruction and declination of environment will increase rapidly.
There are some major negative effect that will appear on environment after some years are explained below:
1. Extinction of millions of wildlife and decrease in trees
Due to restless cutting of trees day by day and hunting of wildlife we can easily say , there will be extinction of millions of wildlife and decrease of trees in 50 years. Deforestation become a major problem of today's world . Due to the deforestation , wildlife lost their habitat and didn't get enough food for feed and become extinct . We already lost many species of wildlife and number of extinct animal will increases . Deforestation not only affects wildlife extinction but it also cause of many natural disasters like flood and soil erosion . There will be problem of drought due to deforestation .
2. Increase in water pollution
Water is vital source for living beings survival including man . There are many water sources like river , lake , pond , ocean , sea etc . Due to human activities like throwing garbage , use pesticides to kill fish increase water pollution . 50 years later many water resources will be polluted very badly and the aquatic life will be affected . Most of aquatic species will lost their life . Human races will also face the problems due to water pollution. Human will affected by many borne disease due to water pollution in future .
3. Increase in air pollution
Due to rapid increase in air pollution , We can easily imagine the future of environment and all living beings after 50 years . There are many industries , company and millions of vehicles , which are the source of air pollution . These number will may be doubled after 50 years. Then you can imagine how air pollution affect the environment . There will increase of different poisonous gas like carbon dioxide , carbon monoxide and others many which affects environment and life of living beings . Air pollution also affects the ozone layer depletion , due to which harmful Ray's of ultraviolet enter on earth and human beings will faced many disease like skin related disease and others .
4. Overpopulation
Overpopulation will be the biggest challenge for all human beings in future. More population mean more consumption of natural resources and need more space . We know that the land is limited it cannot be expand but population can increase . Due to on overpopulation many natural resources will be destroyed to fulfill their basic requirements. There will be problems of starvation can be seen in many part of world due to overpopulation.
5.Global warming
Global warming means increase in the average temperature of the climatic system of earth. Some years later , the global warming will be increases and there is extreme heat on earth . Due to human activities like burning fossil fuel , farming increase in greenhouse gases and it was the main cause of global warming. There will poor air quality on atmosphere . Many disease will appear like asthma and heart related illness . The number of death will increase on both rural and urban areas.
