Unfortunately, the activity of burning or combusting fossil fuels releases various kinds of hazardous substances and pollutants which eventually leads to changes in the environment; such as climate change, global warming, and changes in environmental health. Let us start with the change in climate or climate change. For over the past 150 years, the burning of fossil fuels, such as coal and oil have caused the concentrations of heat-trapping "greenhouse gases" to increase significantly in our atmosphere. These gases prevent heat from escaping to space, somewhat like the glass panels of a greenhouse. It would change our climate, but it would not bring us close to the level of uninhabitable Venus.
The 11th Hour shows us the consequences of irreversible global warming that have already begun to affect our life and environment. The film cites many recent climate change and natural disasters. Throughout the facts, we see that human life must depend on the natural environment. According to Thom Hartmann, “We are a part of nature. We can’t separate from nature.” As DiCaprio tells us we cannot survive without nature.
Oil spills have a number of effects on the environment and economy. On a basic level, oil will damage waterways, marine life and plants and animals on the land. An oil spill can also ruin the infrastructure and economy of a particular area with the long-term effects being felt for generations. Cleaning an oil spill is very expensive and the costs get spread to government agencies, non-profits, and the oil transport company itself. There is no set science for an oil spill clean-up.
Since the temperatures have started to rise, the ice that they once lived on has melted and they are having a very difficult time surviving. People have increased the temperature of the Earth by contributing their pollution. Burning fossil fuels and forests has been the biggest issue amongst us all. Simple changes could help in simple ways but the fact is that since it is a global issue, the world has to be involved in order to make a difference. The United Nations has contributed in this way by holding meetings to discuss the climate changes throughout the world and what can be done to help.
In recent years there has been a growing awareness of the extent to which human activities, such as deforestation and fossil fuel burning, have directly or indirectly changed the biogeochemical and physical processes involved in determining the earth's climate. These changes in atmospheric processes can disturb a variety of ecosystem services that humans depend upon. Humans clearly disturb many, if not all biogeochemical cycles and in the process threaten many ecosystems. In recent years human activities have directly or indirectly affected the biogeochemical cycles that determine climatic conditions of earth. The following summary is how human activities have contributed to disruption of biogeochemical cycles (M Moses et al., 2010): Use of phosphorus fertilizers: Human influences on the phosphorus cycle come mainly from the introduction and use of commercial artificial fertilizers.
Factors of concern, such as ecosystem composition and pathogen virulence, are said to be related to climate changes. Climate change will have significant effects on wildlife, domestic animal, and human diseases, according to scientists. There is scientific agreement that the world’s climate is changing and that the evidence demonstrates that global warming and climate changes are happening. It is anticipated that continuing changes to the climate will have serious negative impacts on public, animal and ecosystem health due to extreme weather events, changing disease transmission activities, new and old diseases, and changes to habitat that are important to wildlife conservation. It’s very important to know that the majority of recent emerging diseases have a wildlife origin.
This combination makes waters toxic to crayfish, clams, fish, and other aquatic animals. It also affects the food sources of herbivores and insects. How does acid rain affect the environment? Acid rain has a hand in global warming as well which is rapidly changing climates around the world. With the climate changes many plants and animals are having to relocate or are dying because they are not fit for the changes in their surroundings.
They lose their habitat and forced to move to new location; besides, many cannot survive the deforestation that destroys their homes. It is undeniable that deforestation itself has extreme effect on Global warming and hurts the air. Global warming means that air and ocean temperature is increasing. Greenhouse gases exist primarily because of human activity. Unfortunately, humans are the most polluting species on the planet.
Diesel exhaust is a major contributor to air pollution and health effects associated with air pollution. To understand the dangers of diesel exhaust, you have to know what is in the fuel first and why people choose to use it. Many studies have shown that diesel fuel may be or is a cause for concern. However, scientists have also come up with different ways to prevent the continued use of diesel fuel. Many people will not agree with the expulsion of diesel fuel, but they must understand the adverse effects it may have.
The issue that the relationship between human activity and climate change is increasing concerned. Climate change is probably the greatest threat to global ecosystem. Climate is the average weather and influencing by slow changes in features like the ocean, the land and the orbit of the earth about the sun. Attribution to natural and human factors, human activity, to some extent, plays an important role in climate change (UNEPWMO, 2004, P5). This essay clarifies several parts: how human activity influences the climate change, the role of human activity, the impact of natural events.
