Threats to Environment: Natural threats and human threats

 Introduction

                                Not all the changes to the planet's ecosystems are perceived as problems. Only those that affect us are, particularly those that affect us now. All our problems are caused by only us. 
Ecological problems grow faster than the rate of population and the growth of world 🌎 economy.

Threats to the Environment

There are many threats to the Environment. These threats are divided into 2 categories. Natural threats and Human threats. Natural threats consists of earthquakes, volcanic eruption, landslides and cyclones.

Human mediated threats consists of deforestation, destruction of habitat and pollution.

Natural threats

Earthquakes



Earthquake is a trembling or shaking movement of the earth's surface. Most earthquakes are minor tremors. Larger earthquakes usually begin with slight tremors but rapidly take the form of one or more violent shocks and end in vibrations of gradually diminishing force called aftershocks.


Volcano







A volcano is a vent in the Earth's crust through which gases, molten rocks or lava and solid fragments are discharged. This study is known as volcanology. Volcanoes are described as active, dormant or extinct.


Landslide 



A landslide is a rapid slipping of mass of earth or rock from a higher elevation to a lower level under the influence of gravity and water lubrication.


Human mediated threats 

Deforestation

 Deforestation is the conversion of forested area to non forest ed areas. 
In other words, deforestation is the result of the removal of trees without sufficient reforestation.

Agents of deforestation

The agents of deforestation can be individuals or groups of individual that are clearing the forest. Commercial farmers, slash and burn farmers, cattle ranchers and loggers are all the agents of deforestation. Agents are usually acting in thier own self interest.

Pollution



Pollution is the contamination of the environment as a result of human activities. The term pollution refers primilarly to the fouling of air, water and land by wastes

Conclusion

As I said in the introduction the human mediated problems are caused by us and it can also be solved by us. To solve these problems we must take care of the environment. 
Environment conservation is essential to our survival.

  Priming or pre studying  Have you ever thought 💭 of creating meaningful relationships with the content you learn ? Yes, but how to do that, after watching some YouTube videos on learning and priming this is my overview of what I learnt  1. Try it  1st thing to find the learning objectives go through it get a rough idea 💡 about it don't try to memorize and  don't try to find the minor details for each concept get an rough idea about it.  Try to find bold letters and keywords Try to find relationships and create your own hypothesis. It may be wrong but give it a try and once you start actual studying find the gaps in it . By doing this we are creating a imagined story in our mind it can be true but by doing this, we are creating relevance within ourselves with the subject as once relevance is formed there is no need to memorization.  So the first part is to scope the information for about 10 minutes .  what to do in lectures ? DON'T WRITE when t...
