 INTRODUCTION 

Our environment is constantly changing.There is no denying fact about it. Therefore, as our environment changes, there is need to become more aware of the problems that surrounds us. With a massive influx of natural disasters , warming and cooling periods, different types of weather patterns and much more.  

People need to be aware of what type of environment issue our planet is facing. For instance, global warming has become undisputed fact about our current livelihoods.

 Our planet is warming up and we are definitely part of the problems. Around the world, people are facing a wealth of new and challenging environmental issues everyday, some are small and affect a few ecosystem. While others are drastically changing the landscape of the earth. 

Environmental issues are defined as problems with the planet system ( air, water, soil etc) that have been developed as a result of human activities or mistreatment of the ecosystem. environment problems makes us vulnerable to disasters and tragedies, now and in the nearest future. There are so many environmental issues . 

1.Pollution 

2.Global warming 

3.Deforestation 

4.Loss of biodiversity 

5.Climatic change 

6.Ozone layer depletion 

7.Acidic rain 

8.Over fishing 

9.Green house effect  

10.Land use. 

GLOBAL WARMING 

Global warming is an aspect of climate change, referring to the long-term rise of the planet's temperatures. It is caused by increased concentrations of greenhouse gases in the atmosphere, It is also a gradual increase in the overall temperature of the earths atmosphere generally attributed to the greenhouse, effect causes by increased level of carbon dioxide, CFcs(Chlorofluorocarbons), and other pollutants. Global warming is the long-term heating of Earth’s climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere. 

CAUSES OF GLOBAL WARMING 

The Greenhouse Effect: Is a natural process that warms the earth’s surface. When the sun’s energy reaches the earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases these gases could be water vapor, carbon dioxide, nitrous oxide, ozone etc. 

The Influence of Human Activity on Climate: human activity has influenced global surface temperatures by changing the radioactive balance governing the earth on various timescales and at varying spatial scales. The most profound and well known anthropogenic influence is the elevation of concentrations of greenhouse gases in the atmosphere. Humans also influence climate by changing the concentrations of aerosols and Ozone and by modifying the land cover of Earth’s surface. Increase in Average Temperature and Temperature Extremes: one of the most immediate and obvious effects of global warming is the increase in temperatures around the world. The average global temperature has increase by about 1.4 degree Fahrenheit (0.8) degrees Celsius) over the past 100 years, according to the National Oceanic and Atmospheric Administration (NOAA).
