Our ecology is on the brink of a disaster due to adverse human activities for centuries. From the streets of Manhattan to the remotest corners of Africa, man has mastered the art of damaging his environment.
The wonder of the universe is so old compared to the existence of humans that we have learnt to take it for granted. Air, water, land, flora, fauna have always been there; and will always be. The disintegration of our vital atmosphere has been like slow poison. We realized the damage too late.
Scientists reckon that the globe is warming and will continue to do so due to the “greenhouse effect”, causing considerable shift in our weather patterns.
The negative effects of Global warming are heat waves, unusual warm weather, ocean warming, rise in sea level, droughts and floods and coastal flooding, warming of Arctic and Antarctic zones, changes in the pattern and amount of precipitation, species extinction and melting of the glaciers which have proven to be extremely dangerous.
Environmental pollution is increasing with every passing year and causing grave and irreparable damage to the earth. It consists of five basic types of pollution, namely, air, water, soil, noise and light all contributing to health problems and a lower quality of life.
The preservation, restoration, or improvement of the natural environment from industrial waste, raw sewage and oil spills by wise control of industrial and other pollution, responsible waste management and recycling is now the need of the hour.
Environmental impact of pollution can be seen in the deaths and in billions dollars property damage that tornadoes, hurricanes and tsunamis cause leaving behind long-lasting legacy of environmental damage.
One of the greatest hazards of industrial revolution is Acid rain. It affects the whole environment from flora, fauna, soil as well as water bodies by accelerating weathering and faster corrosion process. Effective protection of the environment is critical to sustainable development. Practices such as organic farming, sustainable forestry, natural landscaping, wild gardening or precision agriculture, sometimes combined into sustainable agriculture, are increasingly becoming part of nature and ecology conservation.
Environmental disasters like Chemical Spills, Earthquakes, War, Floods, Hurricanes, Landslides, Monsoons, Nuclear Disasters, Oil Spills, Tidal Waves, Tornadoes, Volcanoes, Wildfires are now horrifying facts for us to face.
