These chemicals will wash off and affect the water as the substances can be harmful and could reduce the water quality. Invasion of exotic plant species into wetlands and create large ecosystem changes. The introduced species can create monocultures, and outsource native plants and reducing habitat availability. Weeds also prevent fauna from accessing the water therefore causing the indigenous plants reduce in numbers. Fires, floods and droughts are natural damages to wetlands.
Land pollution causes the land’s productivity and potential to decline to such a level that the purpose of utilising lands for building infrastructures, housings, services, agriculture, forestry and many more for the development of human being are no longer achievable (Prabhakar, 2012). Land pollution are resulted by some sources which are deforestation, mining and construction activities. Deforestation appears to be the major concern as once the land is converted into dry lands, it can hardly be made fertile again. Those areas inevitably end up as waste lands. Mining requires the removal of topsoil containing valuable organic matters.
Because of this demand, their living space needs to be expanded in order to grow food and provide homes for people. Hence, deforestation increases. This is another effect of overpopulation that impacts the worsening of the environment . For example decreased forest size increases the amount of carbon in the environment. More specifically, deforestation affects the wildlife and results in biodiversity loss and species extinction .
This result not only loss ecological balance but also impact directly on human societies. In the environment aspect, firstly they disturb animal habitats leading to ecological destruction. Furthermore, forest fires contribute to global warming which has the devastating effect on the planet. In term of economy, when fires approach homes can burn properties and damage to forestry areas, the whole communities have to be evacuated. The last one is effect on society.
“It is estimated that in 100 years, there will be no rainforests left. The rate of deforestation is equal to the loss of 20 football fields every minute.” (“Deforestation Facts” 1) As a result, there are fewer trees to absorb carbon emissions and groundwater, which affects climate and the water table. Deforestation is the loss of trees, usually due to manmade causes, such as urbanization, mining, logging, and agricultural activities. One of the most overall effected forests is the Amazon. The world’s most expansive forest, the Amazon, is the site of the greatest projected loss of natural life-sustaining habitat and beauty due to deforestation which makes efforts to conserve the forest and save its defenseless inhabitants a critical priority and essential duty of our time.
Rainfall decreases severely causing a fall in food production therefore a loss of some species. However if rainfall increases it can cause the spread of diseases amongst plants, humans and animals through. Flood washes away biodiversity, submerge it and even kill it, similarly draught causes the death of species as there is low rainfall and scarcity of food. Furthermore climate can alter PH levels in rivers, dams and more specifically in oceans and on land. Therefore favorable living conditions are changed to unbearable conditions thus increasing pollution both on land and water.
They make the air harmful to breathe. Exhaust gasses caused acid rain, which dissolve ground and it is killing insects. Also natural caused make air harmful to breathe, like volcanoeruptions and forest fires.When volcano erupts, there is a lot of smoke and sand in the air, soflights can be cancelled, air isn´t good to breathe and all plants and forests can be destroyed, too.The effects of air pollution are quite severe; heart attack, asthma, bronchitis, headaches, cardiovascular problems and other diseases. We can fix this problem by using more public transport and sowing trees,because only they can save the air. They produce oxygen from carbon
Food security issue has many reasons such as population explosion, climate change, agriculture problems and lack of awareness of the problem. Starting with the first reason, the population explosion is one of the most common reasons affecting the food security problem, which is defined as the lack of balance between (the increase in the number of births) and the resources available in a particular country. Global population growth leads to the inability of some countries to meet the needs of the people and as a result upset the balance of living
Anthropogenic activities are conducted citing development, and the same affects the land drastically, they witness land pollution; by drastic they are referring to any activity that lessens the quality and/or productivity of the land as an ideal place for agriculture, forestation, construction etc. The degradation of land that could be used constructively in other words is land pollution. Land pollution is caused by harmful pollutants that contaminate land. Contaminating land can be done in different ways such as: polluting ground water which causes illness to people leaving around the area, and using polluted water. Land pollution is localised and its effects on living beings residing near the area are drastic.
Our environment also affects our physical health. The contamination of water drives out or kills fishes, making it difficult for fishermen to catch fish. The destruction or pollution of land makes it difficult for farmers to grow and harvest crops. The bad quality of air brought about by mining activities degrades the health of the people residing in those
