This research examines the effects that humans have been inducing on the ocean and how the pollution produced is affecting the form of life present there. There is plenty of evidence that the oceans have deteriorated at the hands of humans‚ but recent investigations show that deterioration‚ especially at the sea coasts‚ has increased significantly in the last years due to increased industrial discharge. Common synthetic pollutants that reach the ocean include pesticides‚ herbicides‚ chemical fertilizers

Plastic Pollution Introduction The world population is living‚ working‚ vacationing‚ increasingly conglomerating along the coasts‚ and standing on the front row of the greatest‚ most unprecedented‚ plastic waste tide ever faced. Washed out on our coasts in obvious and clearly visible form‚ the plastic pollution spectacle blatantly unveiling on our beaches is only the prelude of the greater story that unfolded further away in the the world’s oceans‚ yet mostly originating from where we stand: the

Not only are they biodegradable‚ but also disposing of them has their own risks as they release harmful toxins into the air and surrounding soil and ground water. All these cause water pollution .! What is water pollution? Water pollution is the contamination of water bodies (e.g. lakes‚ rivers‚ oceans‚ aquifers and groundwater). Water pollution occurs when pollutants are discharged directly or indirectly

Introduction to Air Pollution Air pollution is the presence of foreign substances in the atmosphere‚ emitted by industries and motor vehicles that cause damage to living organisms. Air pollution characteristics Air pollution characteristics in a particular region are influenced by: The type and amount of pollutant and their source of emission. The topographical and meteorological conditions affecting dispersion‚ concentration and transboundary transport of pollutants. The type of technology

Noise Pollution Construction sites‚ highway traffic‚ emergency sirens‚ and barking animals are not just an inconvenience to the ear‚ but what researchers call noise pollution. Disturbing sounds such as these can interrupt sleep‚ a family dinner‚ or any other normal activity‚ and as a result reduces the quality of one’s life. Although it is looked over by many; noise pollution can have serious negative effects on the environment and the human body. The environment is effected greatly by loud sounds
