Some greenhouse gases, such as fluorocarbons (CFCs, HFCs, PFCs, etc.), are human-made. Others, such as water, methane, and carbon dioxide, are naturally produced. Which type of greenhouse gas (human-made or natural) is more difficult to control and eliminate? Which types are easier? provide evidence for your argument.
Wetlands are able to remove nutrients and chemicals from water as the water flows through the area. A developer is planning to destroy most of the wetlands near a bay. In three to five sentences explain how destroying the wetlands would impact the bays water quality and ecosystem.
Commercial agriculture can often lead to water-quality problems. In one to two sentences, explain how two of those problems occur.
The green house gases are those gases that are known to prevent the escape of infrared rays and ultimately lead to an increase in the temperature of the earth.
These green house gases could be natural or artificial. The natural greenhouses gases are more difficult to control because they can alaso be produced in natural processess that are not subject to human control.

Controlling and eliminating human-made greenhouse gases is generally more difficult than natural greenhouse gases. This is because human-made greenhouse gases are usually produced through industrial processes and are released in large quantities, often at concentrated sources. Additionally, these gases have long atmospheric lifetimes, allowing them to persist in the atmosphere for a long time. Natural greenhouse gases, on the other hand, are part of natural cycles and their emissions are usually balanced by natural processes.
For example, fluorocarbons (CFCs, HFCs, PFCs) are very potent greenhouse gases that have been primarily used in industrial applications such as refrigeration and air conditioning. They have a long atmospheric lifetime, ranging from several decades to centuries, which means they can stay in the atmosphere for a long time and contribute to global warming. Efforts to control and eliminate these human-made greenhouse gases include the Montreal Protocol, an international agreement that phased out the production and use of CFCs.
On the other hand, natural greenhouse gases like carbon dioxide and methane are produced through natural processes such as respiration, decomposition, and natural geological activities. While it is possible to reduce emissions of these gases by implementing sustainable practices, the scale and complexity of controlling natural emissions are challenging. However, natural greenhouse gas emissions can be influenced by human activities such as deforestation, the burning of fossil fuels, and agricultural practices.
In conclusion, the control and elimination of human-made greenhouse gases are generally more difficult due to their concentrated sources, long atmospheric lifetimes, and the industrial processes associated with their production.
Destroying wetlands near a bay would have a significant impact on the bay's water quality and ecosystem. Wetlands play a crucial role in improving water quality by acting as natural filters. They capture and remove excess nutrients, sediment, and pollutants from the water as it flows through the wetland. By destroying the wetlands, these filtering mechanisms would be lost, leading to increased nutrient and pollutant runoff into the bay. This can cause eutrophication, harmful algal blooms, decreased oxygen levels, and overall degradation of the water quality. Additionally, wetlands provide important habitat for various species, so their destruction would disrupt the bay's ecosystem and biodiversity.
Commercial agriculture can contribute to water-quality problems through various mechanisms. One problem is nutrient pollution caused by excessive use of fertilizers. When these fertilizers are applied in large quantities, the excess nutrients can end up in water bodies through runoff or leaching. This can lead to eutrophication, where an excess of nutrients causes rapid algae growth, reducing oxygen levels and harming aquatic life. Another problem is the use of pesticides and herbicides in agriculture. These chemicals can also end up in nearby water bodies through runoff, leading to contamination and potential harm to aquatic organisms and ecosystems.
Determining whether human-made or natural greenhouse gases are more difficult to control and eliminate can be subjective as it depends on various factors. Human-made greenhouse gases, such as fluorocarbons, are typically released in concentrated amounts and have longer atmospheric lifespans, making them harder to control. On the other hand, natural greenhouse gases like water, methane, and carbon dioxide result from natural processes and are more dispersed, making it challenging to control their emissions. To provide evidence for this argument, one can refer to scientific studies and data that highlight the challenges faced in reducing human-made greenhouse gas emissions compared to managing natural sources.
If the wetlands near a bay are destroyed, it would significantly impact the bay's water quality and ecosystem. Wetlands act as natural filters, removing nutrients and chemicals from water as it flows through the area. Without wetlands, the nutrient and chemical load in the water entering the bay would increase, leading to imbalances in the ecosystem. This can result in harmful algal blooms, loss of biodiversity, increased turbidity, and reduced water quality.
Commercial agriculture can contribute to water-quality problems in several ways. One problem is nutrient pollution, where excess fertilizers, such as nitrogen and phosphorus, wash into water bodies, leading to eutrophication and harmful algal blooms. Another problem is pesticide contamination, where pesticides applied to crops can leach into groundwater or runoff into nearby water bodies, potentially harming aquatic organisms and human health.
