Write a 150-word essay describing the effect of people's activities on the environment in the region.

       People's activities, if they are of commercial nature, often leave a negative impact on the environment. Humans have ceaselessly been exploiting the natural resources hosted by the surrounding environment so that the routine and commercial human activities can be performed flawlessly.

       This has, in turn, resulted in the degradation of the environment in a number of ways. Various forms of pollutions caused majorly through the commercial activities of humans have contaminated almost all the abiotic substances like water, air, soil, etc.

       Though abiotic, these substances form the basis of favorable living conditions for the entire biotic population on the planet. There are also a few activities performed by the people that help the environment thrive and protect itself from the negative impact caused by other human activities.

       These activities include reducing, reusing and recycling of non-biodegradable waste, planting of trees, implementing measures for the conversation of environment and the components in it, etc.
