We have been hearing and reading about animals and natural resources being in danger due to human activities from a long time. Many animal species have vanished from the face of earth, we are facing an unpredictable and harsh weather, potable water is scarce, oil and gas are depleting, forest cover is reducing at an alarming rate and new diseases are cropping up all the time. All these dangerous and alarming changes are happening around us every day and we are the ones bearing all the burnt. Though we humans are only responsible for all this, yet we fail on our commitments to saving our environment everyday.
Today there has been a startling exposure by National Center for Ecological Analysis and Synthesis, USA, that 96% of the world ocean has been damaged by human activity. The rate of damage is varying and directly depends on the degree of human contact.
This damage is caused by multiple factors like:
• Discharge of solid waste, toxic chemicals, manufacturing waste, fertilizer, radioactive waste, plastics, oil etc. in to the seas
• Passenger cruises disposing tons of waste every year.
• Polluting the sea water surface through air
• Dynamic changes in temperature and radioactive background
• Seismic surveys
• Industrialized fishing
• Oil containers spilling millions of gallons of oil
• Commercial cultivation of some species
• Destruction of the shore line
• Building new islands
• Sea floor drilling
