Pollution is the presence of harmful substances that contaminates the environment. In today’s century it’s majorly human driven. And its effects can be assessed in the form of its types. Air pollution occurs when harmful substances are released which pollutes the air and negatively impacts the environment in the form of global warming as well as the health of . According to UNEP, air pollution kills an estimated 7 million people each year and is the biggest environmental risk of our time.
Apart from air pollution, soil pollution is also a major contributor for climate change. Soil pollution is the contamination of soil by harmful chemicals such as CO2 and solid and liquid waste that is directly dumped on the soil. The dumping of trash and other wastage destroys the fertility of soil as well as results in biodiversity loss due to soil erosion and hazardous substances present in the soil. Facts speak that “land degradation is a major contributor to climate change and climate is foreseen as a leading driver of biodiversity loss.”
Land pollution caused by unsustainable use of soil, contamination of soil through chemical substances, dumping wastage directly on to soil, unplanned Urbanization and the usage of excessive pesticides and toxins to keep bacteria and insects away from crops also paves way for water pollution.
As Water pollution occurs when land wastage is directly thrown into seas and oceans which not only just pollutes the water but also poses a serious risk to the healthy survival of water species. Around 700 species are known to have been affected by plastic pollution “Every year, about 8 million tons of plastic waste escapes into the oceans from coastal nations. That’s the equivalent of setting five garbage bags full of trash on every foot of coastline around the world”.
