Due to human activity, our planet has been slowly depleting over the years and has been recently increasing. The problems of global warming and climate change have risen due to the carelessness of the human population. Some of the problems happening to the planet is depletion of the ozone layer, the increase of endangered animals, and a decrease of natural resources. Many people fail to realize that our species is the reason this planet is dying. Increasing populations mean a higher demand for resources which will not be here forever.
Pollution begins with the emission of greenhouse gasses into the atmosphere, mostly CO2. These gasses begin to deplete the ozone layer which is the layer that is protecting the planet from the harmful sun rays. The ozone layer plays a very important role for our planet since it absorbs the majority of ultraviolet radiation that is reaching the earth from the sun. Over the years as the human population increases the ozone layer is depleting at an increasing speed. Not only do humans affect the ozone layer, but a decrease in the ozone layer also affects the human population and even animals. Not only will our ozone be torn apart, but the air we breathe could eventually be toxic. As pollution increases, it also has a tremendous effect on rainfall. The toxins in the air are consumed by clouds and combined with water which will lead to acid rain. Acid rain will not only harm humans but will also harm rivers and lakes which humans use.
A thinner ozone layer increases the chances humans and animals of getting skin cancer. With this layer filled with “holes”, the planet begins to warm up resulting in global warming and climate change. As a result, the icebergs in the North begin to melt which will ultimat...

...is waste being dumped into the ocean and trash is being thrown in the streets which flow down street drains and end up in the ocean as well. Our oceans end up polluted which will also affect the animals living in it.
Humans contribute to the depletion of our planet in various ways, many little things cause a chain reaction which ends up being huge drawbacks. We have serious impacts on the planet, humans fail to realize everything they do has a consequence. Whether it’s taking long showers or long drives, doing this every day for a century has slowly deteriorated the Earth. Drastic climate changes have happened before but over many centuries which gave species time to adapt to new conditions. Now it is happening faster than it 's ever had. People don’t treat the planet the way it has treated us and eventually it will be too late to be kind to it and try to restore it.
Stratospheric ozone absorbs 97-99% of ultraviolet radiation. As this protective layer continues to dissentigrate, human health will suffer. One American dies every hour from skin cancer, a direct result of ozone depletion by anthropogenic chemicals, primarily CFCs, which damage the ozone layer. Alternate chemicals are now being used in the place of CFCs that will not damage statospheric ozone, and there is international recognition of the importance of developing these chemicals. The Montreal Protocol is an international treaty which limits the production of ozone depleting substances. Still, human health is at risk from the deletion of ozone, and the risk factor will continue to rise unless people and industries become more aware of the implications connected with everyday use of chemicals which destroy stratospheric ozone.
Pollution is a massive problem, due to burning excessive amounts of fossil fuels and produces global warming. The rising in temperature of earth has resulted huge melting of polar ice caps, flooding of low-lying areas, and also rise in sea levels. If these conditions conquer the surface of earth it will face radical changes. Hence, the ozone holes are also being created trough this process, that creates a harmful UV rays that enters the earth surface. Apparently it affect human life trough causing diseases like cancer. Melanin that present in the skin reacts trough these high wave radiations. Skin cancer is one of the major forms of disease that known to be caused due to these reactions of the pigment present in the skin and infra-red rays. Besides that, when burnt sulphur, dioxide gas will also be produced. This factor forms acid rain. Acid rain could leads to destructions of most of monuments that were made up of brickwork or marbles. Even a lot of crops are affected due to the acidification of loams.
Climate Change is an ongoing problem that continues to intensify as time goes on and not much is happening to change it. Material consumption and increasing populations are increasing the issue of climate change and ruining Earth’s ecosystems. Since the Earth’s population is growing and fast, people are using more energy and materials, which raises great concern. The human ecological footprint has grown so much over the past few years that it is almost irreversible if not changed quickly. Climate change is the most important threat to the Earth and many factors lead are to blame, fossil fuels, greenhouse gases, and carbon dioxide. It would although be ignorant to say that man has nothing to do with it, as the population increases, the need for natural resources, use of more fossil fuels, more waste is produced, the is more pollution which leads to the ozone depletion causing global warming and essentially climate change overall. Since man has the ability to cause such harm to the Earth, man should change their ways to reverse the damage.
As humans, people have their own free will and mind to make their own decisions. What several people are ignorant in is the fact that the usage of an abundant of necessities is depleting at quicker speeds as the population grows over the years. Due to this fact, the earth and the people living on it has been and will be suffering from the widespread consumption of the natural resources that are crucial for everyday life. As the population increases, the consumption does not decrease and people’s unawareness to the world is destroying the planet they call home. Furthermore, the future becomes grim as society continues to act without changing their ways and living up their name as a “super predator” for themselves. Without the balance necessary for the planet, this is one punishment that humans are now facing in the present and future without worrying that the earth deserves fair treatment. As the population increases, humans are facing an exponential growth relating to the consumption rate as the earth deteriorates from the unsustainable lifestyle of
Pollution is causing the destruction of environments and habits resulting in many adverse affects. The types of environments that are heavily damaged by pollution is normally freshwater ones. Polluting factors such as untreated sewage, mining waste, acid rain, fertilizers and pesticides
The ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger, additional ultraviolet rays are allowed to pass through. These rays cause cancer, cataracts, and lowered immunity to diseases.1 What causes the depletion of the ozone layer?
Today's waters are constantly being treated like sewage dumps or trash cans. We use them as garbage cans every day polluting the water more and more. "Pollution is often by way of rivers, drains and outflow pipes." Causing an outflow of sewage into our ocean waters. This is not only affecting the community but also the marine life and other sea creatures living in the ocean." This pollution includes human sewage and domestic waste water, factory outflows of acids and poisonous metals, engine oil from roadside drains and garages, farm chemicals washed off the land by rain, building-site rubble, nuclear waste from power plants, and oil from wells, refineries, and tankers." Stating that most of today's waste is from factory or factory ran products that shouldn't be polluting the water
There are many kinds of air pollution. The ones I want to talk about are the ozone, acid rain, carbon monoxide and toxic air contaminants. Ozone is formed when hydrocarbons and nitrogen oxide react in sunlight. Therefore, ozone is at its peak during hot summer days. Exposure to high levels of ozone can have serious consequences on your health. It can cause respiratory disease, loss of pulmonary elasticity, and premature aging of our lungs. Next, is acid rain, which occurs in the atmosphere in the form of sulfur and nitrogen oxide. These pollutants can have serious damaging affects on aquatic, forest and wildlife ecosystems, as well as deterioration of buildings. Carbon monoxide is another form of pollution. It reduces the blood?s ability to carry oxygen. If a human is exposed to higher levels, it can cause chest pains, angina attacks or even death.
Our planet is suffering from severe pollution, which ranges from contaminated air, water and soil as well. Humans are doing nothing to reduce the amount of pollution that is harming our earth. To understand how pollution works first you must understand that there are different types of pollution. The most common types of pollution and the ones that I will be focusing on which are the ones doing the most harm to our planet are air pollution, water pollution, soil contamination and littering. In order to help out and reduce pollution in our planet people need to be more aware of what these problems are and about the severe damages that they are causing our planet. Before industrialization really jumped into place and had an effect on large cities, nature had its own way of cleaning up its own air and itself. Wind scattered gases, rain washed many substances and the rest dissolved into the ground; while plants absorbed carbon dioxide and made it into oxygen. With big cities growing more every time and with more towns that were becoming more industrialized a lot of more waste began to be released into the environment and the atmosphere and soon this was more than enough for nature to handle. In order to stop and reduce pollution people need to understand the damage that it is causing our environment and our planet as well. People need to be more aware of how they can help out and do their part in reducing these problems that are causing our planet to die slowly with people not even noticing it.
Pollution is so harmful to human beings. Polluted water can cause many kinds of diseases, such as diarrhea, enteritis, and so on. And sometimes the diseases even take man’s life. Dirty air or air-borne garbage causes stinging eyes and running nose. Pollutants are destructive. They will cause runs in stockings and crack rubber tires and they always eat away at stone and rust iron. Time and time again, there are serious accidents that polluted the air. For example, At 1986 there was a bad accident at a nuclear power station in Russia. A cloud of radiation crossed the whole Europe. It is said that 125,000 people died in Russia as a result of illnesses caused by that accident. In 1984 there was an accident at a factory in India and a dangerous cloud gas covered the town of Bhopal. Over 2,500 people were killed that night, and hundreds and thousands of people were injured. Many of the injured lost their sight, and it really dangerous, even in our imagination.
Many scientists have declared that humans are the cause of the next mass extinction. One way that humans have pushed the earth to the next mass extinction is through the process of global warming. Scientists spent time studying the mechanisms of climate change on ecosystems and concluded that there is a major link between these two (7). Overpopulation of humans is one of the main causes of the higher extinction rates (1, 2). It causes humans to invade other habitats that other organisms used to dominate. Also, it results in a lack of resources for the species. This overpopulation also causes overconsumption by humans on earth (1). The overconsumption results in too much predation on other species for food or for pleasure. Many other species provide resources that humans want for various forms of pleasure, so they are killed or manipulated as an industry. There are some areas that had little to no human influence like the protected national park only a short distance from Bangkok, Thailand. This area was very healthy the first few trips there, but, as humans have slowly invaded this area, the scientists have been able to notice the declining health of this forest. All of these things point to the direct link between humans and the next mass
What is pollution? Pollution is a detrimental enemy to all species that walk on earth. It is a product of mankind carbon foot print on the environment. It consists of chemicals or particles in the air that can harm the health of humans, animals, and plants. Pollution occurs when pollutants contaminate the natural surrounding; which brings about changes that affect our normal lifestyles adversely. Pollutants are the key elements of pollution which are generally waste materials of dissimilar forms. Pollution disturbs our ecosystem and the balance in the environment. With innovation and development in our lives pollution has reached its peaks; giving rise to global warming and human illness. When raw materials, water, energy and other resources
Overpopulation can be seen as one of the key factors responsible for the state of our rapidly decaying earth. Developments in medicine, agriculture and technology have allowed for the human race to take over all other species and be excluded from the natural food chain. Humans, particularly westerners, lead lives of extreme consumption that take huge tolls not only on the earth but also on certain groups within society. A great division has developed between the western world and the third world.
Efforts to improve the standard of living for humans--through the control of nature and the development of new products--have also resulted in the pollution, or contamination, of the environment. Much of the world's air, water, and land is now partially poisoned by chemical wastes. Some places have become uninhabitable. This pollution exposes people all around the globe to new risks from disease. Many species of plants and animals have become endangered or are now extinct. As a result of these developments, governments have passed laws to limit or reverse the threat of environmental pollution.
Pollution is a massive problem that the earth faces. Pollution is the action or process of making land, water, air, etc…, dirty and not safe or suitable to use. Pollution of air, water, and soil are the most complex issues. Various types of gases and toxins that are released by industries
