India will host this year’s World Environment Day today (June 5) and the government has announced that the country will continue to play a very important role in defining the terms of environmental debate at the global level.
Each year a different country is chosen as the principal venue for the global celebration of World Environment Day which falls on June 5 and the United Nations Environment Programme (UNEP) has selected India as the global host of this year’s programme.
The theme of this years celebration is “Forests: Nature at Your Service”, which highlights the crucial environmental and economic roles played by the forests, particularly in India.
“The message is largely to the international community that India is willing and determined to play and is playing a very important role in defining the terms of environmental debate,” Environment minister Jairam Ramesh in his message to the world on the occasion, PTI reports said.
Threat to the environment!
The rapid growing population and economic development is leading to a number of environmental issues in India because of the uncontrolled growth of urbanization and industrialization, expansion and massive intensification of agriculture, and the destruction of forests. A proper study needs to be undertaken to identify the negative impacts of these chemicals that contaminate land, water and air. This hazardous waste is being produced by various countries and poses serious risks to not just the people and the environment but, it also has the potential to contaminate other non-hazardous waste and substances if it is not adequately controlled.
Types of hazardous wastes
There are several types of hazardous wastes which include-Industrial waste, which comprise of oil sludge, waste oil and oil soaked rags etc. The next form is the Municipal Solid Waste, which is generated from residential dwellings, offices, hotels, canteens etc. and finally we have Biomedical waste, which is generated from hospitals and animal houses.
How does it affect us?
When hazardous wastes are released in the air, water or on the land they pose greater threats to our health. A hazardous substance can cause injury or death to a person, plant or animal under conditions like when large amount is released at one time, the substance is very toxic or if the substance is not diluted etc.
Now, when a person comes into contact with a substance, this is referred as exposure. The effects of exposure depend on factors like how the substance is disposed of, the amount of exposure, the time period of exposure etc.
Humans, plants, and animals can be exposed to hazardous substances through inhalation, ingestion, or dermal exposure.
