Environmental pollution In this topic we are going to deal about different types of pollution and due to these types of pollution how our environment is facing disasters and calamities. Introduction: Environmental pollution can be defined as “the unfavorable alteration of our surroundings” Types of pollutants: 1. Bio degradable pollutants - decompose rapidly by natural processes. 2. Non-degradable pollutants-do not decompose or slowly decompose in the environment. Pollutions are different

Air Pollution To understand pollution of air‚ some knowledge of the atmosphere is required. Atmosphere is a layer consisting of a few gases surrounding the planet earth and is vital for the survival of life on earth. The atmosphere protects earth from abrupt temperature fluctuations from the powerful ultra violet radiation coming from the sun. The atmosphere is made up of nitrogen 78%‚oxygen 21%‚argon 0.9%‚carbon dioxideo0.03% and small amount of trace gases ‚helium ‚neon‚ krypton‚ xenon‚ hydrogen

POLYTHENE POLLUTION INTRODUCTION The pollutants that are of major concern in today’s world are non biodegradable pollutants that do not degrade or degrade very slowly in the natural environment. Polythene pollution is an example of non biodegradable pollution and they persist on our earth years after years affecting even future generation. Polythene pollution is mostly created by polythene bags‚ plastic syringe‚ pesticide containers‚ medicinal bottles. [pic] Effects of Polythene Pollution Polythene
