In this Presentation we will study about which are the factors and things that pollute our environment.. Harm the human health, effect the ocean life in different ways, and how it impact on environment.. we will also discuss about the reasons and procedures that how we can prevent our environment from the harmful things... and what role we can play to keep our environment clean and healthy

1. Impact of Human

5. Human impact on environment
Means
• Human activity has had an effect on the environment for
thousands of years.
• In ways both positive and negative—and likely in more ways
than you’d even think—human civilization and technology
have affected our earth, altering our planet forever.
• Humans impact the physical environment in many ways:
overpopulation, pollution, burning fossil fuels, and
deforestation.
• Changes like these have triggered climate change, soil erosion,
poor air quality, and undrinkable water.
• These negative impacts can affect human behavior and can
prompt mass migrations or battles over clean water.

8. Deforestation
• Population growth leads to the loss of natural habitats.
• Cut down tress to build new homes
• Loss of biodiversity
• Loss of oxygen producers and CO2 eliminators
• 18 million acres of trees are clear-cut every year

10. Over population
• Over population is becoming a serious issue in Pakistan.
• the population is larger then the country as the population is
increasing day by day, the current population of Pakistan is
208.57 million.
• Over population effects on the economic development in the
developing countries like Pakistan, one of the main reasons of
poverty, illiteracy, and low living standards in our country is
high rated population growth.
• Pakistan is 5th highest populated country in the world.
• If we compare Pakistan with other highly populated nations
Pakistan has the smallest amount of space, it means Pakistan
deals with the more difficulties then other highly populated
countries.

14. Pollution
• Pollution is not just limited to the air.
• It can affect soil or waterways and can come from human
waste, industrial chemicals and other sources.
• Pollution is so bad that to date, 2.4 billion people do not have
access to clean water sources.

16. Air Pollution
• Skin Damage Many of the chemical intolerances directly affect
people’s skin. However, one of the worst damage is skin
cancer.
• Global Warming Probably global warming is one of the most
worrying effects for scientists and environmentalists. Global
warming is a direct consequence of the greenhouse effect,
which is produced by the high emission of CO2 and methane
into the atmosphere.
• Climate Change Climate Change is another consequence of
global warming. When the temperature of the planet
increases, there is a disturbance in the usual climatic cycles.

18. Water Pollution
There are 5.25 trillion pieces of plastic debris in the ocean.

20. Land pollution
• Land pollution, in other words, means degradation or
destruction of the Earth’s surface and soil, directly or
indirectly, as a result of human activities.
• Groundwater Poisoning
• Drinking-Water Problem
