Environmental Changes




WHAT IS ENVIRONMENTAL CHANGE?

Environmental change is a change disturbance of the environment most often caused by the human influences and natural ecological process. Environmental changes include various factor such as natural disasters, human interferences, or animal interaction. Environmental changes encompass not only physical changes, but also factors like an infestation of invasive species. Extreme weather conditions have been on the rise across the globe for decades. We’re experiencing hotter summers, colder winters, wider temperature swings, rising sea levels, reductions in sea ice levels, shrinking glaciers, increased storm activity, and more. As the weather gets more extreme, so does the polarized debate over climate change. Lets see in detail of environmental change as per physical and biological factor .

 

PHYSICAL FACTORS

Geology plays an important role in the environment. The most important geological factors effecting environmental change include volcanism, erosion and weathering.

Volcanism introduces new minerals into the soil as well as gases into the atmosphere. The introduction of minerals nutrients into the soil is one reason why volcanic soils are among the most fertile in the world. Volcanoes can also change the composition of the atmosphere by emitting gases such as carbon dioxide and Sulphur.

Plate tectonics causes volcanism. It also creates mountains and valleys. When mountains are formed through tectonic uplifting, this changes the gradient of slopes and can increase the amount of erosion from wind and water. The increase in erosion increases the amount of sediment and the nutrients that enter rivers, valleys, and oceans. This can have a significant effect on the local environment over time. A change in the availability of nutrients from erosion could cause a shift in an ecosystem.

BIOLOGICAL FACTORS

Introduction of new organisms can also cause significant environmental change. This includes invasive species. A famous case would be Christmas island where an introduction of yellow crazy ants has led to the disruption of the local ecosystem and threatens the local crab population. Another example is the introduction of Argentine ants to places all over the world. These ants are becoming major pests and are causing serious problems for the native ant populations that are vital to local ecosystems. Humans have probably been one of the most influential species in modern times in shaping the environment and causing environmental change. Humans are the cause of a growing mass extinction, the reduction in forests worldwide, and the rapid growth of a new biome, cities.

Do you now believe that our Environment is changing ?

    Human interference is destroying our environment.the least we can do is reduce the use of Fossil fuels.

Save Earth by Rainwater Harvesting

Image
  Why Rainwater Harvesting is Crucial to Solving India’s Water Woes Over the last few years, we have seen a  significant decline in the supply of water  available to us. Water shortages have increased all over the world, which is why measures need to be put in place to help reduce the high rate of water loss. Rainwater harvesting is a way of conserving water that can help combat the problem. If we do not take the right steps now, there is an imminent danger of severe water shortage in the future. In this blog post, we discuss the various rain water harvesting methods that you can implement based on the kind of home you live in. What is Rain Water Harvesting? So what exactly is rain water harvesting? It is a technique or strategy for the collection of rain water and a way to store it in the right way for future use. There are many different rain water harvesting methods that use different kinds of surfaces and platforms. In rain water harvesting, the water can be c...

Effects of Environment Changes The effects of environmental changes can be catastrophic and far-reaching, affecting all aspects of life on our planet. Here are some potential repercussions: 1. Loss of Biodiversity : Environmental changes can cause the extinction of species and loss of biodiversity, disrupting entire ecosystems and threatening the balance of our planet's natural systems.       2.  Habitat Destruction : Changes to the environment can lead to the destruction of habitats, such as forests and coral reefs, which can have cascading effects on the entire ecosystem.       3. Climate Change : Environmental changes can cause climate change, leading to rising sea levels, more frequent and severe natural disasters, and altered weather patterns that can cause droughts, floods, and wildfires.       4. Health Impacts : Environmental changes can have significant health impacts, including air pollution-related re...
