What is climate change in simple definition? 
Climate change is 
the long-term alteration of temperature and typical weather 
patterns in a place
. ... The cause of current climate change is largely human activity, like 
burning fossil fuels, like natural gas, oil, and coal. Burning these materials releases what are 
called greenhouse gases into Earth's atmosphere.

Pollution
is an environmental concern for people throughout the world. One university 
study suggests that 
pollutants
in the water, air, and soil cause up to 40% of the premature deaths 
in the world's population. The majority of these deaths occur in 
developing countries
.

Water in many developing countries is 
contaminated
with 
toxic chemicals
, also known as 
toxins. The World Health Organization (WHO) estimates that 1.1 billion people have little or no 
access to clean water. In many of these regions the water that is used for drinking, cooking, and 
washing is the same water that is used for dumping 
sewage
and 
hazardous waste
. Most 
developing countries cannot afford water treatment facilities. Approximately 80% of infectious 
diseases in the world are caused by contaminated water. 
Air pollution is a growing problem throughout the world. Indoor air pollution is one of the 
leading causes of lung cancer. Families in developing countries use open stoves for cooking and 
heating their homes. These homes do not have proper 
ventilation
. The smoke, which is full of 
chemicals and 
carcinogens
, gets trapped inside where families eat and sleep. Outdoor pollution 
also causes disease and illness, especially in 
industrial
cities such as Beijing, China, where 
cancer is the leading cause of death. China relies heavily on coal, which is considered the dirtiest 
source of energy. According to the European Union, only 1% of urban dwellers in China breathe 
clean air on an average day. Neighbouring countries including Japan and Korea receive much of 
China's pollution in the form of 
acid rain
. This pollution results mainly from the coal powered 
factories, which produce inexpensive goods for North American and European consumers. 
Outdoor air pollution is also a concern in many wealthy countries. Those who live and work in 
urban centres such as Los Angeles or Toronto experience many warm days beneath a layer 
of
