“Earth provides enough to satisfy every man's needs, but not every man's greed.” ― Mahatma Gandhi

Climate change is the biggest global-health threat of the 21st century. The world has warmed by 0.5°C over the past century. Small changes in the temperature of the planet can lead to potentially dangerous changes in climate and weather. Human activities have released large amounts of carbon dioxide and other greenhouse gasses into the atmosphere.

Environmental Issues

1.Population: According to UN estimates, by the end of the century the world’s population might be as high as 17 billion. With the growing population, urbanization wave will continue for many years to come bringing enormous changes to landscapes and lifestyles.

2.Climate Change is one of the biggest environmental issues. Human activity causes changes in the climate posing risks for a broad range of human and natural systems. Over the last century, the global average temperature has increased by more than 1.4 degrees Fahrenheit. Rising global temperatures lead to changes in weather.

3.Pollution is the presence or introduction of contaminants into the natural environment that causes an adverse change in an ecosystem. Various forms of pollution that have an effect on the environment include air pollution (from natural and man-made sources), soil pollution (when chemicals or other substances are released into the ground), and water pollution (discharge of wastewater from the industry into the surface water). Every year over 1 million seabirds and 100,000 sea mammals are killed by pollution.

4.Loss of Biodiversity: The term biodiversity refers to a variety of life on Earth at all its levels from genes to ecosystems. Rising population, habitat loss, pollution, over-exploitation of natural resources have a huge impact on biodiversity. It’s our duty to protect the biodiversity. The loss of biodiversity threatens the food supply chain.

5.Endangered Species: Endangered species is a group of organisms which are at risk of becoming extinct. Endangered species are threatened by factors such as habitat loss, hunting, wildlife trade/animal poaching and climate change. Overfishing has led to the extinction of southern blue tuna. Hunting is one of the biggest threat to the tiger’s (national animal of India) survival. An increasing demand for tiger’s skin and parts used in Traditional Chinese Medicine has resulted in dwindling numbers. Between the years of 2000 to 2014, 1590 parts of tigers were identified in places where tigers roam.

World Environment Day is celebrated on 5th June to raise awareness about key environmental issues. Every person has some form of impact on their natural environment. Simple efforts taken by an individual can help protect the environment.
