How Do Volcanoes Effect Our Environment?

Volcanoes affect the weather we experience. Near where the volcano erupts there is often a lot of rain, lightning and thunder because ash particles are thrown up into the atmosphere attracting water droplets. 
When volcanoes erupt they emit a mixture of gases and particles into the air some of them, including sulphur dioxide (found in ash), have a cooling effect. Other such as C02, add to the greenhouse effect that causes global warming.
Some of the cooling effects of volcanoes are noticeable such as Mount Pinatubo in 1991 which caused a dip in global temperatures in the following few years.  As for greenhouse gases, underwater and land based volcanoes release around 100m tonnes of CO2 each year; that is a very large amount.
Volcanoes also affect people in many ways. They destroy houses, buildings and roads; leaving them covered in ash. However, as long as you can get ash off, your house may not collapse.  Volcano explosions can also produce ash clouds which poison the environment; lava solidifies to make mountains and eruptions can result in the death of animals and plants. However, the effect of volcanoes is not always bad as they serve as a shield for people, especially bush men. Volcanoes also act as a source of water because of the hot water springs they produce and sometimes they can help to modify the climate of areas since they interfere with clouds to create orographic rainfall.
Volcanoes are a source of rich and fertile agricultural soils because most of their material contains minerals good for vegetation growth.

The most powerful, the most spectacular volcanic eruptions often occur in subduction zones. The volcano may be quiet here for several hundred years later, erupted, but once it started, power is particularly fierce. Such as volcanic eruptions often would bring disaster to mankind.
1 affect the global climate
A large number of volcanic ash and volcanic gases, causing a great impact on the climate. Because in this case, the dark and stormy day, and even mud rain will be troubled by the local residents for several months. Volcanic ash and volcanic gas has been sprayed into the high altitude and going, they'll wind spread to distant places. These volcanic materials will cover the sun, causing temperatures dropped. In addition, they also filter out certain wavelengths of light, making the sun and the moon looks like a veil of halo, or suffused with exotic colors, especially in the sunrise and sunset when the formation of unusual natural landscape .
2, damage to the environment
Volcano emitted a large number of ash and rain combine to form debris flow can be washed away roads, bridges, flooding nearby villages and cities, has left countless people homeless. Soil, rock debris to form the slurry can be like a flood inundated the whole city in general.
Although the rock is volcanic ash clouds covered, but the volcanic eruption had just been sprayed into the air can still see the huge rock.
3, back to life
Volcanic eruptions on the far-reaching impact of the natural landscape. Land is the world's most valuable resource, because it breeds all sorts of plants to support everything. If the volcanic eruption of farmland to give less than 20 cm thick covered with volcanic ash, is something that can really Xicongtianxiang farmers, because these nutrient-rich volcanic ash make the land more fertile.
After the collapse of lava, weeds, moss began to emerge.
Rope-like lava flow slopes grow ferns.
Volcanic ash to the surrounding fertile land, the local grape harvest every year.

Volcanoes have a negative and positive effect on our environment. The high content of sulphur makes the air not suitable for inhalation but the soil around volcanoes is very fertile. Also volcanoes form new land masses. Also volcanoes heat underground water thus producing hot springs and geysers 

It affects the environment when it erupts because it sometimes reaches the plants and that is where we get oxygen so we will have less oxygen.

Well pyroclastic flows are made from dangerous gases and can blow over trees. When the lava comes down it can kill of vegetation by burning it from intense heat. Ash fall usually effects plant growth

Volcanic activity has killed more than 260,000 people, destroyed entire cities and forests, and has severely disrupted local economies for months to years. Even with the improved ability to identify hazardous areas and warn of impending eruptions, increasing numbers of people face certain danger. The ozone is also said to be damaged by this.

They burn down all the trees and kill all the little animals.

Volcanoes can destroy homes but is good for plants(fertilizer)

Volcanoes produce more CO2 then humans. But the soil around the volcano is very good.

The mudflows make the soil more nutrients and the lava solidifys making mountains the ash clouds poson the environment.

Heavy ash may fall and make roof's fall down. People could die.

The magma or lava that comes out of the volcano forms hard rock and if the the ash touches water it forms land.Volcanoes also destroy homes but  it is also used as a fertilizer for plants.

In the Mount St Helens eruption long term changes are Spirit Lake being filled in, an extended area around Mt St Helens completely covered in volcanic rock and the volcano shape changed. Spirit Lake was filled in as a result of the lava mixing with ice flowing and then flowing into the lake. The lava then cools forming a rock. When the lava from the volcano mixed with ice from the outer rock mixed this flowed fast destroying everything but also leaving a rocky layer behind. When the volcano erupted it created a landslide this was the reason that caused the change in shape of the volcano.

The ash is good at collecting water making it rain more

They destroy the trees and forests and animals living around the volcano. The animals around the explosion would die as well

They tend to take a liking to what you have eaten today, and then decide -based on that- to eat you or smeet you. They normally smeet you. In other words, they normally eat you.
