The various human activities has polluted our ecology impacting the nature with several environmental issues. Environmental issues occurs at three levels which are: local, regional, and global issues.

Local Environmental Issues

• Waste Disposal

Every area should have a proper way of waste management and disposal. We need to keep our hometown clean just like our home not so for outsiders or to attract touristsbut for our own well-being too. Improper management of waste harms the environment and our health through water and air pollution.

• Water Scarcity

Water is a basic necessity for every living being. There is no life without water. For us humans, we cannot spend a day without water. Water is required for many human activities in our day to day life. We need water for washing, cooking, and drinking everyday. It is hard to imagine our life without water. Hence, we should save water and teach others to do so too.

• Pollution

Pollution is caused by daily human activities whether intentionally or unintentionally. Water and air is polluted heavily through the human practices which is dangerous for our own health and environment.

Regional Environmental Issues

• Overpopulation

Global Environmental Issues

• Global Warming

Global warming is the long-term rise of the temperatures on the Earth’s surface. It is caused by human activities such as burning of fossil fuels, and industrial release of greenhouse gases like carbon dioxide and methane into the atmosphere. Global warming leads to uneven weather patterns, rising of sea level, melting of glaciers, and early maturing of crops to list its few outcomes.

• Climate Change

Climate change is caused by the increase of greenhouse gases in the Earth’s atmosphere. The increasing amount of release of these gases has lead to high heating from the sun. Climate change as well leads to unpredictable weather forecast, global temperature rise, melting of glaciers and so on.

• Use of Natural Resources

Humans beings around the world are using natural resources at a great extent. Human are greedy for resources, and sometimes consume even more than required. This is having a negative impact on the environment. The overuse and overexploitation of natural resources is leading to its reduction which is indeed a global concern.
