When population increase, the consumption of resources increase. Therefore, a lot of factories have been built and a lot of lands have been used to get rid of different kinds of waste. For example, in lots of major cities in China, there are hundreds of factories that make it difficult for Chinese people to breathe naturally because the air is polluted. In addition, polluted air has become the biggest problem to the human on the earth because it causes some dangerous diseases such as respiratory diseases and heart diseases and sometimes leads to death. According to World Health Organization, around 4.5 million people die each year from air pollution.
“As the population rises, the world 's water usage will rise. Many areas of the world already suffer from a lack of fresh water,” (Population Control 3). If the world runs out of freshwater, humanity will plunge into chaos. Humanity needs water to survive, and that is a fact. Relationships between countries will be broken apart over disputes for water.
This is because as the human population develops, so does the pollution we create. This is also why humans are the cause of climate change and most of the problems seen in the environment today. Consequently, because of our actions,
The detrimental impacts of human-generated pollution on our environment and what the world is doing about it The world is becoming more and more aware of the detrimental impacts of human-generated pollution. Most of the energy we use comes from burning fossil fuels that causes air pollution, smog, acid rain, global warming and other adverse environmental impacts. The availability of clean water is quickly diminishing with pollution and increased demand due to population growth. With all of these negative affects the evidence points to an extremely destructive future for our environment and quality of life that has triggered public concern. The health of the world’s water supplies available for human consumption, irrigation or recreation is not well.
It is either created by human or nature as global phenomenon. Water consumption has been increased at more than twice of the population. Even there is no holistic water scarcity, the increasing number of areas are desperately needed water resources. There is enough water supply on earth for all people but it has become imbalance because of the unevenly water distribution. Half of the world population lives without adequate water and sanitation.
Even though, an increase in the production of goods and services can be economically beneficial for the nation, we cannot eliminate the disadvantages they can bring to a high number of populations. Due to all the ‘chemical and radioactive substances’, water has become more contaminated, and the air we breathe is becoming more polluted (ATSDR, 2008). Environmental changes that I have mentioned above would not be a huge problem, if it contained only a certain region or small population. However, air pollution, deforestation, ozone hole, water contamination, and greenhouse gases not only affect one nation in the world, but they are global concerns. Since it affects the whole population, it is more than significant to take human security issues into
Advantages of Fossil Fuels: Fossil fuels originate from dead plants and animals. They have been buried underground under large pressure and have become organic fuels sources for today’s use. Some of these fossil fuels include: coal, natural gas, and crude oil; all of these are hydrocarbons. When these fuels are combusted they produce a lot of thermal energy that is used to heat up water, produce steam, and generate electricity through a turbine. Since fossil fuels are our main source of electricity production and are in large need for other things like transportation and the manufacturing of plastics, fossil fuels have become increasingly available.
BIOFUEL ADVANCES AND ITS APPLICATION - A REVIEW Abstract 1. INTRODUCTION Our main energy sources for human activity are fossil and mineral fuels, nuclear sources. They are harmful to environment because they cause ozone layer depletion, global warning and ecological devastation. Actual energy production can be considered a harmful both in pollution and environmental impact since the industrial revolution in the 18th century. Around 80% of CO2 emissions in the world are originated by the energy sector.
Industrial Emissions: in the process of creating products to be used for various issues, industries end up emitting large quantities of toxic wastes and fumes which end up causing pollution. Fossil fuels: petroleum and coal are among some of the leading causes of fossil fuel pollution. Discussion Patterns of environmental
Every year, globally, we consume the equivalent of over 11 billion tons of fossil fuels. Many countries have started to invest their money in thoroughly researching and inventing alternative energy sources. Apart from polluting the environment, fossil fuels are also harmful to living things like plants and animals. They are responsible for sudden climatic changes and greenhouse gas effect. Fossil fuels are nonrenewable, hazardous to environment and are also becoming very expensive.
